Abstract

Introducing secondary cementitious material (SCM) helps reduce CO2 emissions in the cement and construction industry, during and performance advantages, including low permeability, resistance to chlorides and sulfates, mitigation of alkali-silica reaction, greater strength, and lower temperatures for mass Concrete and improved workability. Industrial waste such as SCM, such as fly ash, slag, silica fume, volcanic ash, and other by-products from the different process mixing with clinker and gypsum, in varying proportions, at the grinding stage of blended cement manufacturing. A new SCM as Limestone Calcined Clay Cement (LC3) is a unique material that is also a cementitious material for the future to reduce dependency on industrial waste as SCM. In this paper usage of LC3 and its impact and benefits are discussed.

Keywords: Clinker, Durability, Hydration, Kaolinite, Pozzolana.
