The building materials industry is constantly changing and faces many challenges. This requirement is increasing, especially in the face of ever-increasing globalization.

The increasing consumption of energy sources such as oil and coal is reducing the world’s limited resources. Large quantities are used in the production of building materials. Our innovations conserve global reserves by using alternative, recycled and environmentally friendly raw materials.

Climate change is predominantly attributed to unchecked anthropogenic CO2 emissions since the beginning of industrialization. The production of cement is one of the largest sources of carbon dioxide in the world due to its high energy requirements. By using secondary raw materials from industrial processes, we reduce the cement content and make a significant contribution to climate protection.

Increasing health problems in the processing of building materials are leading to stricter product labeling. We reduce the critical components. Silicate products replace questionable organic components without any health risks.

The products used on construction sites have to meet increasingly stringent requirements every day. Higher strength, better resistance, durability and more flexibility are just a few examples. There are also other important aspects such as environmental friendliness.

Research & Development


As part of national and international research projects, we support our partners as a technology provider, developer and producer. Using the unique technology of upcycling and activating alternative raw materials, such as blast furnace slag, we develop products adapted to the requirement profiles of the projects, the market or our customers.


Research and development have always been pillars of our company philosophy and are an ongoing process that we face every day. Over the years, we have successfully realized a large number of projects and new developments in cooperation with our partners.
