KELLER participates in the state programme

As a participant in the state programme, KELLER has signed the charter on reconciling work and care and is a reconciliation partner. The care guide person at KELLER provides initial information and orientation on the compatibility of work & care on a collegial basis and informs about external assistance and regional counselling networks.

Balancing work and care is becoming increasingly important. The number of people in need of care and thus the number of family carers is continuously increasing. The employment rate is also rising steadily. Consequently, the group of working family carers is growing. At the same time, the lack of qualified personnel continues to worsen in many companies.

There are currently 1.2 million people in need of care in North Rhine-Westphalia (NRW). Most of them are cared for at home by their relatives. In many cases, these carers are employed: An estimated 500,000 working people in NRW care for relatives, partners or friends in addition to their job. It is our responsibility as an employer to take into account the demographic development of society on the one hand and, above all, the needs of our employees who take on care responsibilities on the other.

KELLER HCW has successfully conducted hydrogen firing test under real operation conditions

At the Hagemeister clinker bricks production plant in Nottuln (Germany), bricks were fired with hydrogen under real conditions in a joint project with several partners. This positive and pragmatic success places KELLER now in a position to deliver burner technology for hydrogen operation, together with the required control and safety technology. And thus, it is doing justice to its ambitious claim of increasing energy efficiency and reducing CO2 emissions in the bricks and tiles industry.

The test operation with hydrogen is part of the research project

3D printing for the flexible and environmentally friendly production of concrete parts

The machinery and plant manufacturer KELLER, with its headquarters in Ibbenbüren-Laggenbeck in North Rhine-Westphalia, is one of the most important companies of the region. For many years, KELLER has been developing plant and machinery solutions at the highest level not only for the heavy clay industry but also for other building materials. An interesting new development is the KELLER 3D concrete printer “3DCP”.

Digitalization in the building sector The introduction of digital printing technology is transforming the world's traditional construction methods in the building sector. The global visionary interest in serial and modular 3D concrete printing “3DCP” is also increasing to the same extent. The digitalization is the driving force with the aim to improve the economic productivity, to manage the valuable human resources, to gain precious time and at the same time to enable something really unique with the use of CO2-reduced concrete recipes. KELLER recognised the growing potential of using additive manufacturing in combination with 3D concrete printing in the building industry a few years ago and invested in research and development projects to realise a fully automated 3D concrete printer based on an industrial robot application (Photo 1). The new possibilities of 3D concrete printing application paired with a linear axis system and the addition of a colouring medium in the print head are numerous. This enables the production of individual objects that are not feasible with conventional concrete casting methods (Photo 2). These can be smaller components or large, fully printed modular building parts and civil infrastructure components. An industrial robot in combination with a linear axis system offers a wide range of possibilities in the design and function of products. To round off the system and the products, a colourant can be added via the print head at the same time (Photo 3).

A major advantage of the technology is the digital consistency of the planning and building process, as it is largely independent of seasonal and regional weather conditions.

3C/three-component 3D concrete printing 3C refers to the number of components in a material to produce the final product. These can be processed with KELLER's high-tech 3D concrete printer. The fibrous micro-concrete system essentially consists of the components dry mortar, superplasticizer and accelerator. The patented mixing system requires a mixing time of only 3 seconds. With the micro-concrete, a precise and high-quality print can be produced even at a very fast printing speed of 0.3 - 1.5 t/h. The accurate grain size distribution ensures a smooth and aesthetic object surface. The periphery of the fully automated 3D concrete printer can regulate the mixing ratio of the components according to the object in order to ensure the speed of absorption, the viscosity of the mass, the thixotropic consistency of the flow property and the optimum setting time.

Affordable housing units The construction of affordable housing units usually depends on two main variables: the cost of the materials used to build the housing units and the structural size. Significant advances in off-site construction can provide innovative solutions for affordable housing. A lack of available resources and skilled personnel requires a sustainable rethink and a different approach to the way construction is organised and operates, and is crucial to the future of affordable housing.

Environmentally friendly buildings The intelligent combination of the fully automated KELLER 3DCP technology and the micro-concrete system results in a remarkable synergy that combines numerous environmentally friendly aspects. By systematically applying these innovative approaches, the building industry can sustainably improve its impact on the global environment.

Better CO2 balance The micro-concrete system itself is an environmentally friendly technology developed with a focus on sustainability. Compared to conventional concrete compositions, the micro-concrete system has a better CO2 balance. In combination with KELLER 3DCP printing technology, the environmentally friendly advantages are multiplied. 3D concrete printing allows for precise and efficient use of materials, reducing the overall amount of building material required and therefore taking fewer resources from the environment. In addition, the precise layering and controlled placement of the micro-concrete system through 3DCP technology optimises structural integrity and eliminates the need for excessive reinforcement or support structures. This also leads to reduced material consumption and rationalised construction processes, which additionally improves sustainability. In KELLER's technology centre at the Ibbenbüren-Laggenbeck site, the future-oriented 3DCP technology is constantly being further developed in order to implement technical solutions in practice together with interested parties.

Future Day 2023

On April 27, some students got a taste of our apprenticeship professions. The nationwide campaign day (formerly "Girls'Day, Boys'Day") for girls and boys is held every school year at all general education schools for grades 5 - 9. On this day, students are given insights into various professions that are suitable for expanding the traditional, gender-specific spectrum of possible professions for girls and boys. They can take part in activities in companies, colleges and institutions and are thus encouraged to explore professions that they themselves usually do not consider. Four girls and eight boys visited KELLER. In the morning, the young people were given an insight into the professions of industrial mechanic and industrial clerk. After a small snack, at this point a big thank you to Burger Bench https://burger-bench.de/ for the great preparation, they went on to the areas of electronics technician and ceramics laboratory. It was an exciting and informative day! Many thanks to all!
