EXPANDABLE POLYMER CONCRETE

摘要

A polymer concrete which does not shrink as it cures, comprising a mineral aggregate; a polymer matrix from the group consisting of acrylic, polyester, vinyl ester or epoxy resin, for binding the mineral aggregate; a hydrated mineral filler in powder form; the aggregate, polymer matrix and filler being in the sizes and amounts that at least one of (i) the polymerization and cross-linking reaction temperatures and (ii) externally applied heat, is sufficient to release enough of the water of hydration of the filler as steam and cause the concrete not to shrink as it cures.
