ABSTRACT:
A polymer concrete comprising by weight about 40-70% coarse aggregate, about 20-55% of a fine aggregate such as sand, about 2-15% silica flour and about 8% to 12% furfuryl alcohol polymerized in situ with an acid catalyst produces a highly cross-linked concrete which contains no cement and is mixed with water. The furfuryl polymer concrete provides the broadest range of chemical resistance of all existing polymer concretes. The coarse and fine aggregate have a pH less than 7.0 and are provided with a specific size gradation.
