Clinker-efficient cements

Increasing the robustness of concrete

The durability of building materials plays a crucial role in the construction of sustainable buildings or structures. This is where concrete can exploit its strengths to the full. For this reason, a major part of the research being conducted at VDZ is dedicated to this key topic. A particular challenge lies in adhering to the political framework for mitigating climate change and ensuring resource efficiency whilst not losing sight of the longevity of concrete structures as an essential component of sustainability. Nowadays, modern concretes are complex systems comprising various raw materials...
