The main source of cohesion in cement paste is the nanoparticles of calcium silicate hydrate (C−S−H), which are formed upon the dissolution of the original tricalcium silicate (C3S). The interaction between highly charged C−S−H particles in the presence of divalent calcium counterions is strongly attractive because of ion−ion correlations and a negligible entropic repulsion ...

Blended cement, as defined in ASTM C 595, is a mixture of portland cement and blast furnace slag (BFS) or a "mixture of portland cement and a pozzolan (most commonly fly ash)." The use of blended cements in concrete reduces mixing water and bleeding, improves finishability and workability, enhances sulfate resistance, inhibits the alkaliaggregate
