What is Supplementary Cementing Materials Guide about?

Supplementary cementing materials (SCMs) such as fly ash, slag, silica fume, and natural pozzolans contribute cementing properties when used with portland or blended cement in concrete. SCMs are used to improve concrete properties such as strength, permeability, and resistance to alkali-aggregate reactivity. Fly ash, slag, and natural pozzolans generally decrease water demand and increase workability and setting time of concrete, while silica fume can increase water demand and risk of plastic cracking.
