Granite has the highest stability of any natural material. The ongoing optimisation of the chemical properties of cement has enabled structural engineers to build constructions of reinforced concrete with exceptional dimensions. However, the requirements of machine construction are generally higher when it comes to temperature stability, tensile strength and vibration characteristics. The special composite material DemTec® that we have developed over the years for such applications fulfils all these requirements. We receive our customers' requirements of component structure, ideal component geometries and reinforcements, which are then generally implemented by our specialists. DemTec® is a composite material which combines a steel (shell) and a special type of concrete with reinforcement.
