Examples are the concretes of the new generation: artificial lightweight aggregates allow us to produce components with improved thermophysical properties or reduced dead load; high-strength concretes can carry extreme compressive forces, the addition of short fibres results in better ductility–and these are just some examples of our current opportunities. On the other hand, through intelligent structural design, eg based on the flow of forces, we can increase the efficiency of structures. These ideas are currently the subject of a priority programme (German abbreviation: SPP) of the German Research Foundation (DFG). In SPP 1542 researchers from various scientific fields are pursuing a fundamentally new approach that will allow lightweight construction with concrete for all structures: all relevant design elements such as floor slabs, walls and columns should have a surface geometry corresponding to the actual, certainly also influenceable, flow of forces in the component itself according to the principle of “form follows force”. The researchers want to achieve two major goals using lightweight construction with concrete: 1. First of all, an aesthetic paradigm change. Enlarging the form spectrum of concrete members, which is defined by the formwork technology common these days, increases the whole creative scope when building with concrete. Our structures should meet the requirements of usefulness, but also satisfy variable usage demands.2. The second idea is that lightweight construction according to the principle of “form follows force” leads to a reduction in the dead weight of the components. In particular, nature can be a role model for us, so the field of bionics will also be important for concrete research in the future. Thus, lighter components also lead to saving natural resources and energy in the production of steel and cement, and in the provision of aggregates. Reducing cement consumption in particular could enable civil engineering to make an important contribution to cutting CO2 emissions.
