Abstract

Procedure for preparing a cement with controlled expansive properties, comprising Portland cement clinker, approximately 2 to 17% by weight of Portland cement clinker of calcium aluminate cement clinker, and approximately 2 to 24% by weight of Portland cement clinker . excess SO3 over optimal SO3 determined by ASTM Standard 0563-70 added as calcium sulfate; characterized by comprising a) determining the optimal SO3 for the Portland cement clinker, b) grinding the Portland cement clinker to an average minimum Wagner surface of at least 1,600 cm2/gm, c) grinding the calcium aluminate cement clinker to a minimum Wagner surface on average of at least 1,350 cm2/g, d) grinding the calcium sulfate so that at least 70% passes through a sieve no. 100, and e) mix to homogeneity the Portland cement clinker and the calcium aluminate cement clinker with a sufficient excess of SO3 over the optimal SO3 determined in step a) added as calcium sulfate to give a cement that has the level of desired expansion.
