Abstract : Precast portland cement concrete specimens were impregnated with monomeric and resinous materials by the brush-on, soak, and vacuum- soak methods. The impregnants were polymerized by the promoted-catalytic or thermal-catalytic methods or with curing agents. Impregnations of specimens with certain epoxies by the vacuum-soak method resulted in reductions in water absorption of over 99%. Impregnations of specimens with methyl methacrylate by the vacuum-soak method, polymerized thermal-catalytically, resulted in compressive strengths as high as 23,750 psi. (Author-PL)
