Geopolymer concrete – sustainable innovation in concrete construction and perfect processing with Kniele KKM cone mixer

What is geopolymer concrete?

Geopolymer concrete is one of the most innovative alternatives to conventional cement-bound concrete. Unlike classic concrete, geopolymer concrete is not based on Portland cement, but on chemically activated aluminosilicate binders and consists mainly of aluminium (Al) and silicon (Si) compounds. These react under alkaline conditions to form a stable, three-dimensional network and form the basis for the high performance of geopolymer concrete.

Raw materials and binders in geopolymer concrete

Metakaolin, fly ash and blast furnace slag are among the raw materials used in geopolymer concrete. In combination with alkaline activators, a polymeric binder system is created that gives the aggregates a strong and durable matrix. This means that geopolymer concrete differs fundamentally from conventional concrete in terms of its chemical structure and reaction mechanics.

Technical advantages of geopolymer concrete

Geopolymer concrete impresses with its rapid strength development, high compressive strength and excellent chemical resistance. Particularly noteworthy are its resistance to acids, sulphates and aggressive media, as well as its high temperature and fire resistance. These properties make geopolymer concrete a high-performance building material for demanding applications.

Sustainability and CO2 savings potential of geopolymer concrete

A key advantage of geopolymer concrete is its significantly reduced carbon footprint. Since no energy-intensive cement clinker is required in the production of geopolymer concrete, emissions can be significantly reduced compared to conventional concrete. Geopolymer concrete thus makes an important contribution to sustainable and resource-efficient construction.

Requirements for mixing technology for geopolymer concrete

The production of geopolymer concrete places special demands on mixing technology. The reactive binders, the high viscosity of the mixtures and the necessary homogeneous activation require intensive and uniform mixing processes. Inadequate mixing can significantly impair the properties of geopolymer concrete.

Kniele KKM cone mixer for geopolymer concrete

The Kniele KKM cone mixer is ideally suited for the production of geopolymer concrete due to its special geometric design. The conical mixing shape ensures a continuous material flow and intensive mixing of all components. This ensures the uniform activation of the binders in the geopolymer concrete.

High shear forces for homogeneous geopolymer concrete mixtures

A key advantage of the Kniele KKM cone mixer is the high shear forces it generates. These shear forces support the fine distribution of binders, activators and aggregates and promote the formation of a homogeneous matrix. Especially with geopolymer concrete, this intensive mixing is crucial for consistent quality and reproducible properties.

Geopolymer concrete in industrial and specialised applications

Whether in research, pilot plants or industrial production, geopolymer concrete is becoming increasingly important. Kniele KKM cone mixer offer powerful mixing technology that is specially designed for innovative and sustainable concretes such as geopolymer concrete. This allows the advantages of geopolymer concrete to be put into practice safely, efficiently and economically.

Collaboration as a success factor: innovation through dialogue between businesses and universities

When business and science shape the future together

How does innovation come about? Often when different perspectives, expertise and ideas come together. This is exactly what happens in successful cooperation between companies and universities. At the Burghausen campus of Rosenheim Technical University, the focus is on dialogue with the regional economy – practical, innovative and future-oriented.

At the „Business and University in Dialogue“ event on 28 October in the auditorium of the Burghausen campus, visitors were able to experience first-hand how successful Kollaboration between business and science come about and what advantages they offer.

Collaboration with added value: research, development and skilled workers

Companies from the region benefit in many ways from close cooperation with Rosenheim Technical University.

Whether in research and development, skilled worker recruitment or dual study programmes, cooperation opens up new ways to drive innovation while promoting practical education.

In inspiring presentations, renowned companies such as ECM Kraftanlagen, Siltronic AG and KNIELE GmbH reported on their joint projects with the university. It became clear that scientific expertise and industrial know-how complement each other perfectly when it comes to developing new technological solutions.

Practical example: The intelligent suspension mixer KIS from KNIELE

An outstanding example of successful cooperation is the joint research project between KNIELE GmbH and the Technical University of Rosenheim under the direction of Professor Johannes Lindner.

The aim was to develop a new type of intelligent mixer that can generate various flow vortices through adaptive control and automatically adapts to torque and drive power – achieved via frequency converters. In addition, vibration sensors for predictive maintenance were integrated and an innovative heating and cooling function for the mixer trough was implemented.

Development work began after successful ZIM funding in 2021. Within around two and a half years, the KIS smart adaptive mixer was created, which was then extensively tested at the Technical University of Rosenheim.

The intelligent mixer is currently being prepared for industrial use. Potential applications can be found, for example, in the field of paper coating – for example, for food packaging that is hygienic, sustainable and non-stick.

KNIELE GmbH is delighted with the excellent cooperation with Prof. Lindner and Rosenheim Technical University – a prime example of how practice-oriented research can lead to marketable products.

Dialogue and networking: exchange, contacts, ideas

At the get-together in the foyer of the Burghausen campus afterwards, participants took the opportunity to make new contacts in a relaxed atmosphere. Representatives from the university were on hand at information stands to answer questions about the wide range of cooperation opportunities – from joint research projects and theses to dual study models.

Conclusion: Cooperation as the key to success

The event impressively demonstrated that when companies and universities combine their expertise, innovations are created that generate not only economic but also social added value.

The cooperation between KNIELE GmbH and Rosenheim Technical University illustrates how scientific ideas can be turned into marketable products – and how important the dialogue between theory and practice is for sustainable economic development.

See you at the next trade fair!

On 30 November 2024, a formative era in the history of Kniele GmbH in Bad Buchau will come to an end: our founder and long-standing Managing Director Erwin Kniele will retire from the three-person management team.

His sons Harald and Alexander Kniele, who have been with the company for over 30 years and already have management responsibility, take over the reins and continue the success story. With Felix and Joris Kniele, the third generation is already in the starting blocks to lead the family business into the future.

The origins of a visionary

Erwin Kniele began his professional career at Liebherr Mischtechnik in Bad Schussenried, where, as a structural engineer, he discovered his passion for the construction of steel structures early on. The path to self-employment began with the further development of the ring-pan mixer. However, the mixing quality at the time left a lot to be desired, so hydraulically operated agitators had to be installed - an expensive and repair-prone solution.

With an approach that was as simple as it was ingenious, Erwin Kniele finally developed a compulsory mixer with two mechanically driven agitators, which is still in use today. This pioneering innovation also marked the start of his independence.

However, his inventive spirit had been with him long before he founded his own company. For example, he developed a bricklaying machine for the Anliker company with which complete brick walls could be prefabricated in the factory - another example of his pioneering ideas and technical innovations.

Milestones in the company's history

On 1 January 1991, Erwin and Lydia Kniele founded Kniele Baumaschinen GmbH. The company developed into an internationally recognised, family-run medium-sized enterprise. From the very beginning, not only the mixing plants, but also components such as scales, dosing flaps and weighing belts were developed and manufactured in-house.

A particular breakthrough came in 2001 with the development of the KNIELE KKM cone mixer. This patented technology - with its unique conical shape - revolutionised mixing technology and opened up new markets for Kniele. The conical mixer is not only convincing in the concrete industry, but is also used in recycling processes, the food industry and many other specialised areas.

For Erwin Kniele, Kniele Baumaschinen GmbH was always more than just a company - it was his life's work and purpose. With tireless commitment and a great deal of passion, he shaped and built up this company.

The inventive spirit remains

Even after his retirement from the day-to-day business, Erwin Kniele remains true to his passion. By developing new mixing technologies, researching innovative cleaning systems and registering further patents, he ensured the continuous innovative strength of today's Kniele GmbH.

On behalf of the entire workforce, family and business partners, we would like to thank you, Erwin, for almost 35 years of tireless commitment, visionary inventiveness and your example as the founding father of our company. Your inexhaustible commitment and your pioneering ideas will always be an inspiration to us. You have not only shaped a company, but also inspired many people. We look forward to continuing to benefit from your knowledge and support in the future.

Load weights for high-voltage cables: Innovation in production with Kniele mixing technology

The production of load weights for tensioning high-voltage cables in rail transportation places high demands on materials and technology. These special weights not only have to be robust and reliable, but also manufactured under extreme conditions such as abrasion resistance and dosing accuracy. Planning for this challenging project began in 2022 and has now been implemented with a successful complete solution from a single source - thanks to the expertise of Kniele GmbH.

Successful mixing trials and decision in favor of Kniele

The path to a tailor-made solution began with mixing trials at Kniele. After the first tests, it was already clear that the combination of Kniele mixing technology and the special raw materials would meet the requirements. This successful collaboration led to the Austrian company Katzenberger opting for a Kniele mixer. What tipped the scales was not only the high quality of the mixers, but also the comprehensive overall solution from a single source that Kniele offered.

Innovative technology for the production of load weights

The production of loading weights relies on modern technology and precise dosing. The raw materials are filled into two big bag emptying stations for metal powder and mixed granulate, which are operated by crane systems. One of the stations is equipped with a buffer container to handle larger storage quantities efficiently. In addition, a silo for binding agents ensures a constant supply for production.

Dosing takes place via special screw conveyors that transport the material into a small mobile weighing container. This container can travel along the production line to three filling points, where it is precisely weighed with the raw materials. The high-resolution scales ensure precise measurement of the individual components.

After weighing, the mobile container is placed on the frame of the Kniele KKM100/150 conical mixer by crane. In the mixer, the metal powder is precisely mixed with the mixed granulate and binder. The dosing of the individual ingredients is controlled by a WMW dosing unit, which ensures precise quantity control.

The challenge of abrasiveness and logistics

One of the biggest challenges in this project was the abrasiveness of the metal powder, which is particularly resistant and abrasive. This placed particular demands on the storage, transportation and mixing of the material. In order to meet these requirements, specially designed systems were used that can handle the material efficiently and safely.

In addition to the technology, a mixer dedusting system was also installed to reduce fine dust during the mixing process. An admixture weigher from Würschum also ensures precise dosing of the additives to guarantee the quality and consistency of the mixture.

Future prospects and success for the infrastructure

Thanks to Kniele's innovative mixing technology and precise planning, Katzenberger was able to develop an efficient solution for producing the load weights. These not only help to improve the infrastructure, but also ensure that the high-voltage lines in rail traffic can be tensioned safely and efficiently.

We wish our customer Katzenberger every success for the future and look forward to further exciting projects! You can find more information on the Katzenberger website Katzenberger.

Sustainable recycling of fine-grained process by-products through fibre-reinforced briquetting

Metallurgical and mineral processes generate large quantities of fine-grained process by-products (PNP) such as filter dust, sludge and granulates. These materials contain valuable metallic and mineral components, but are often sent to landfill due to a lack of economical recycling technologies. Conventional binding methods using cement and water are also associated with high CO2 emissions and are often uneconomical for small, decentralised quantities.

Objective: Cement-free briquetting with recycled fibres

As part of a research and development project at RWTH Aachen University, an alternative, cement-free process for recycling PBNs was therefore developed. The aim is to convert the materials into stable briquettes using fibre-reinforced briquetting. Recycled fibres from old textiles serve as reinforcement material and improve the mechanical properties of the briquettes. This enables economic recycling from as little as around 1,000 tonnes per year.

Technological approach and mixing technology

A central component of the project is the development of a special dosing and mixing technology that allows the airborne fibres to be homogeneously incorporated into the fine-grained PNP. Kniele developed a customised pilot plant based on a modified Kniele cone mixer. The system combines dosing and mixing in a compact unit and allows flexible addition of fibres, binders and water.

The plant is supplemented by an adaptable control system that allows different process phases and recipes to be precisely adjusted. Extensive tests confirmed high mixing quality, low material losses and the suitability of the system for continuous operation and subsequent industrial scaling.

Conclusion

The project demonstrates that fibre-reinforced, cement-free briquetting offers a technologically and economically promising way of recycling fine-grained process by-products. The close cooperation between RWTH Aachen University and Kniele is a successful example of the transfer of scientific knowledge into practical, scalable plant technology and makes an important contribution to resource conservation and CO2 reduction in industry.

Our new CNC press brake for greater precision and flexibility

On November 25, 2024, we took an important step in the further development of our production technologies. Our existing press brake, with a pressure force of 180 tons, was replaced by a used CNC press brake SMD. With a pressure force of 400 tons on a length of 4 meters, the new machine offers us a number of advantages that not only improve the quality of our work, but also increase our efficiency.

Greater performance and more flexibility

With a pressure force of 400 tons, the new press brake is significantly more powerful than its predecessor. This means that we can now easily bend 10 mm thick steel sheets over a length of 4 meters. Thanks to the additional bending aid and the ability to use long bending tools, we can now also bend complete trays on all 4 sides. This gives us greater flexibility when processing components in different sizes and shapes.

Faster processing and ergonomic advantages

Another advantage of the new CNC press brake is the faster processing of large and complex components. The automatic bending aid ensures that even heavy and bulky parts can be processed easily, which not only saves time but also improves ergonomics at the workplace. Our employees benefit from simplified handling.

The new central filling system from KNIELE for company Kessler & Co.

In industrial production, processes such as the plasma cutting of sheet steel generate considerable quantities of metallic waste in the form of dust and slag. This waste not only represents a health and safety risk, but also a challenge in terms of waste disposal. To tackle this problem and at the same time increase efficiency and safety in the workplace, KNIELE has developed an innovative central filling system in collaboration with Kessler&Co.

Challenge: Dust and waste during plasma cutting

Kessler&Co., a leading global manufacturer of truck axles, uses several plasma cutting systems that cut steel sheets around the clock. This cutting process produces large quantities of metallic waste, including dust and slag. To collect the waste, the individual machines are connected to extraction and filter systems that collect the waste in mobile containers. These containers were previously emptied manually with a forklift into open container troughs, which led to high levels of dust and safety risks for the workers.

The solution: Central filling system from KNIELE

With the new central filling system from KNIELE and a conversion of the filter systems from Dodek, this problem could be optimized. The central filling system ensures that the waste is filled into the container skips safely, efficiently and, above all, with little dust. The innovation comprises several components that automate the entire process and at the same time increase occupational safety and environmental protection.

Low-dust docking of the mobile containers

The mobile containers, which are connected to the individual filter systems and filled with slag, are placed on a substructure and connected with a pneumatic docking system. This ensures dust-free emptying and protects employees from hazardous dust exposure.

Wear-optimized screw conveyors and loading equipment

In order to transport the metal waste efficiently, wear-optimized screw conveyors are used, which transfer the waste into the container trough via a loading bellows. The fine filter dust is collected separately and also discharged into the skip via another loading bellows.

Partially automated emptying for greater efficiency

The new filling system partially automates the emptying process. A fill level indicator on the loading bellows ensures that the mobile containers are only emptied when the container skip is not yet full, which increases the efficiency of waste disposal. As soon as the containers are full, they are conveniently collected with a skip loader, which further simplifies the entire process.

Conclusion: More safety and less dust - a win-win situation for everyone

Thanks to the new central filling system from KNIELE, waste disposal in sheet steel processing has been significantly improved. The optimization not only ensures dust-free disposal, but also greater occupational safety and environmental protection. The semi-automated emptying and the pneumatic docking system also offer enormous savings in terms of time and costs. The cooperation with Kessler&Co. has shown how innovative technologies can make production safer and more efficient.

We would like to thank Kessler&Co. for the successful cooperation and look forward to future projects that will make industrial production even safer and more environmentally friendly.

We would like to thank you for the trust you have placed in us as the main supplier to one of the most renowned family businesses in the Upper Swabia region and wish you every success for the future.

The world is becoming faster and more versatile. So are the demands on manufacturers of modern materials. For our customer MIG - Material Innovative Gesellschaft in Salzkotten, North Rhine-Westphalia, we installed a new dry mixing plant for a wide range of building materials and chemical additives at the beginning of 2022.

High product flexibility was the focus of this plant.
Depending on the quantity, the raw materials are delivered either in big bags, in sacks or by silo vehicle. A total of 3 big bag emptying stations, 4 silos and 1 bag emptier are connected upstream of the KNIELE cone mixer. In addition, small components can be fed by hand. The core of the dry mixing plant is a KKM 1000/1500 with 1m³ output. After mixing, the ready-mixed material can either be filled into a big bag, transported into a storage silo or packed into bags in a bagging plant. Truck loading has also been realised.

We wish our customer much success with the new plant and maximum flexibility in his products!

Innovative products for construction not only make physical work easier, but also reduces construction time. With the commissioning of the new mixing plant from KNIELE in combination with a bagging plant from Haver&Boecker, our Austrian customer will be able to produce light plasters as bagged goods in the future.

The cement is conveyed from the silo, which is located outside the hall, into the KNIELE cone mixer KKM via a cement screw. The heart of the plant has an output of up to 375 kg per batch. Styrofoam is fed into the mixer via a pipe conveyor system and mixed with cement and a binding agent.
The big challenge here is to produce a homogeneous mixture of the "heavy" cement and the extremely light polystyrene balls. However, the KKM masters this task within a very short time, whereas other mixers would need several minutes or there would be no mixing at all!
Below the mixer, the material is stored in a pre-silo to continuously feed the Haver&Boecker packaging plant below.

After a big bag emptying station with bag feeding and pipe conveying system was installed for the company AMG Graphit Kropfmühl already at the beginning of 2021, the second construction phase was put into operation exactly 14 months later.

Graphit Kropfmühl is a manufacturer of all products made of graphite, such as powder-metallurgical parts for the automotive industry, carbon brushes for electric motors, insulating materials for the construction industry and many other materials.

At the Hauzenberg site, two more big-bag discharge stations with negative weighing and two bag feed hoppers on a platform have now been installed. The graphite powder is then conveyed into two conical mixers, dosed and mixed.

On behalf of KNIELE, we would like to thank Graphit AMG for the excellent cooperation.

The company CBS Home in Deißlingen produces precast concrete parts according to the CBS system (Compound Building System). Here, the supporting structure, which consists of folded galvanised sheets, is also the formwork for the prefabricated parts - innovative and sustainable at the same time.
The filigree lightweight steel structure is completely encased and filled by the foamed lightweight concrete based on expanded clay.

The heart of the plant is a KNIELE conical mixer KKM 2250/3375 with an output of 2.25m³. The matching feeding system was also supplied by KNIELE. 6 aggregate silos feed a mobile scale via dosing belts. The scale in turn feeds the KNIELE material lift, which transports the mix into the KKM. The feeder lift is equipped with a special fall protection.

Many thanks for the many good discussions and the great interest in our Kniele cone mixers and big bag stations.
