Abstract: From a sustainability perspective, cement based materials are by far the best option to meet the demand for construction materials from a growing world population. Nevertheless, it is crucial to lower their environmental impact. In the presentation first, an outline will be given of the realistic options for reducing environmental impact, which should involve all steps in the construction chain, from cement, through concrete to structures. In our recent report for the European Climate foundation we illustrated that such measures could reduce the CO2 emission from cementitious materials by 80% compared to 1990 level.
Second research questions will be identified which should be answered to achieve further grains in the sustainability of construction materials. The needs for research concern requirements for increasing the use of supplementary materials and revolve around three main areas: Placement; Hydration; Durability. For example, as concerns hydration, early properties are dominated by the clinker component and increasing the reactivity of clinker would allow higher replacement levels. In the area of durability, we need to better understand how microstructure governs transport properties. Our recent work with LC3 materials show that
reductions in chloride ingress are far more than expected from the modification of pore structure and chloride binding.
