Alternative binders (geopolymer concrete, calcined clays) in
precast construction

In the context of mitigating climate change, one of the key demands is to reduce the CO2 emissions generated in the production of cement and the concrete containing it. However, since the process of producing cement clinker is invariably associated with CO2 emissions, the related efforts of the cement industry concentrate not only on increasing energy efficiency and using alternative fuels but also on the substitution of cement clinker. Both cement and concrete producers are in a position to reduce the ratio of cement clinker. In the concrete industry, the preferred substitute is coal fly ash,...
