EXPAN 500 is an expansive cement additive which, when mixed
in certain proportions with type II Portland cement (ASTM C-150),
results in a type K expandable cement (ASTN C-845), used mainly in
the manufacture of Shrinkage Compensating Concrete (SCC).
EXPAN 500
provides an effective and economical way of preventing cracks
caused by drying shrinkage in concrete made with Portland cement.
ASTM Standard C-845 - "Standard specification for expansive
hydraulic cements".
