The influence of supplementary cementing materials (SCMs) on the hydration and durability of blended cement has been evaluated using chemical and physical principles.Similarities and differences between various SCMs has been considered while they have been grouped into categories as latent hydraulic or pozzolanic and sub-divided into siliceous, aluminous, carbonaceous etc.For instance has the important synergy between SCMs producing calcium aluminate hydrate and calcium carbonate been elucidated showing how maximizing water binding leads to reduced porosity and thereby increased strength by forming calcium monocarboaluminate hydrate.Similarly would any magnesium content in the carbonate lead to hydrotalcite formation in the presence of aluminates.
