✦ Synopsis
Impreg~.ated cement p~stes were prepared from fine cement of ~laine area 6~,O m /kg using various initial W/C ratios in the range 0.25-~.70, cured for various durations, an@ 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 me~surable reduction in zero strength porosity, whereas ~igh porosity samples show measurable reduction in the strength at zero porosity. Enhancment of compressive strength takes place at an optimum range of porosity and gel/space ratio.
