ABSTRACT:
A shrinkage compensating cement exceeding the ASTM standard specification limiting 28 day expansion to 115% of the 7 day expansion. 28 day expansions of 120-200% are contemplated. The expansion takes place over an extended period of time, to better offset the shrinkage occurring as the concrete dries. The development of tensile stresses in the concrete is reduced and also is delayed, allowing more time for the tensile strength of the concrete to increase as the concrete dries. Shrinkage cracking is consequently significantly reduced.
