Summary:PURPOSE: A polymer-modified concrete composition is provided to obtain uniform quality by controlling curing period and strength by control mixing weight ratio. CONSTITUTION: A polymer-modified concrete composition comprises 15-20 weight% of quick curable cement, 1-4 weight% of a polymer solid phase, 35-49 weight% of fine aggregate, 30-44 weight% of a thick aggregate, and 5-8 weight% of water. The quick curable cement comprises calcium sulfo aluminate, calcium aluminate, and normal cement. The content of the calcium aluminate is 5-15 weight% based on 100.0 weight% of the quick curable cement.
