ABSTRACT
This paper is devoted to the most important developments in the field of sus-tainable concrete production and evaluates various approaches. In the global con-text of cost reduction and CO2 constraints, producers are striving to lower the ce-ment 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 by-products from industrial manufacturing processes. Such new materials might be able to play a significant role as main cement constituents in the future.
