Process for the preparation of polymer concrete having low shrinkage.

摘要

Polymer concretes having little or no shrinkage and high compressive strength and improved bond are prepared by; A) mixing a current catalyst with an unsaturated resin selected from the group consisting of unsaturated polyesteramide resins, unsaturated polyester resins and unsaturated vinylester resins dissolved in one or more ethylenically unsaturated monomers to provide a catalyzed resin, B) mixing said catalyzed resin with finely divided polystyrene, coarse and fine aggregates, and fillers to provide a curable polymer concrete blend, and C) curing said concrete blend. a
