Shrinkage compensating concrete with expansive additive
An expansive Portland cement incorporating an expansive additive which is a polymer incorporating a calcium compound reactive with the cement is described. The shrinkage compensating concrete produced is much less likely to crack and is used in slabs and other structural systems where cracking of the concrete is a problem.
