Comparative Sulphate Resistance Of Pozzolanic Cement Mortars
, 2017 This is report on experiment out to compare the sulphate resistance of sand mortar made with five different pozzolanic cement. The pozzolanic cement were prepared by blending powered burnt bricks from the Adamawa, Makurdi, Kano, Kaduna and Niger bricks factories with ordinary Portland cement in the ratio 1:4.

Influence of cement properties in the reaction rate and mechanical behavior of concrete with high fl y ash content [PDF]
, 2011 The use of fly ash (FA) as an admixture to concrete is broadly extended for two main reasons: the reduction of costs that supposes the substitution of cement and the micro structural changes motivated by the mineral admixture.
