SUSTAINABLE CONCRETES CONTAINING SUPPLEMENTARY CEMENTITIOUS MATERIALS

This paper is devoted to the most important developments in the field of sustainable concrete production and evaluates various approaches. In the global context of cost reduction and CO2 constraints, producers are striving to lower the cement content in concrete. Limits are set by regional and global availability of appropriate materials. The use of supplementary cementitious materials (SCMs), where no additional clinkering process is involved, leads to a significant reduction in CO2 emissions per ton of cementitious materials (grinding, mixing and transport of concrete use less energy compared to the clinkering process) and also provides the utilization of byproducts from industrial manufacturing processes. Such new materials might be able to play
