COMPRESSIVE STRENGTH VERSUS RESIDUAL POROSITY IN POLYMER IMPREGNATED CEMENT PASTES

Impregnated cement pastes were prepared from fine cement of blaine area 600 sq M kg using various initial water/ cement ratios in the range 0.25-0.70, cured for various durations, and by using styrene or methyl methacrylate, which were polymerized in situ by thermal treatment. The polymer effect on compressive strength was found to be variable and depends on pore size. Upon impregnation, low porosity samples show measurable reduction in zero strength porosity, whereas high porosity samples show measurable reduction in the strength at zero porosity. Enhancement of compressive strength takes place at an optimum range of porosity and gel/space ratio. (Author/TRRL)
