THE INFLUENCE OF POROSITY AND PARTIAL DRYING ON THE PROPERTIES OF POLYMER-IMPREGNATED MORTAR
Source abstract
Abstract
Three mortar mixes of widely differing porosities were impregnated with three vinyl monomers and methanol. The monomers were polymerized thermally using a free radical initiator. Specimens of one of the mortar mixes were dried to different relative water vapor pressures prior to impregnation with either methyl methacrylate or styrene. The compressive strength was determined in all cases and the strains in the partially dried specimens were recorded throughout the processing cycle. The compressive strength of the impregnated mortars was found to be a function of both porosity and the properties of the matrix and polymer. Length changes during processing were dependent on the degree of drying. Maximum swelling in monomer occurred in specimens stabilized at intermediate relative humidities. /ACI/
