Abstract
The reduction of greenhouse gases in concrete construction will be a great challenge for the coming decades. A significant part of the CO2 footprint is caused by cement clinker production. Therefore, a powerful solution is to reduce the cement content in the concrete mixture by using supplementary cementitious materials (SMCs). The water demand also needs to be reduced with regard to the water to cement ratio and performance of concrete required. A new model concept shows the need for an excess of fine grains additional to the normally used optimisation of packing density to reduce the water content without any negative consequences for the concrete characteristics. A new strategy for increasing the water efficiency in the mortar design has been developed at the Institute for Building Materials at Leibniz University Hannover which helps to develop a new cement-reduced 'RedCarb' concrete.
