Abstract

The influence of methyl metharcylate and gamma exposure dose on the physico-chemical and mechanical properties of polymer-alite composite have been investigated. The hardened alite samples were impregnated with a methyl methacrylate monomer and then subjected to γ irradiation doses from 10–50 KGy. The effect of polymer loading (%), compressive strength, bulk density and the microstructure (scanning electron microscopy SEM), in addition IR spectra were studied. The results indicate that, polymer loading, compressive strength and bulk density increase with increasing absorbed dose. This is attributed to the deposition of the polymer in the pores of the samples. SEM showed the voids between the particles in the samples before the impregnation, whereas, the formation of new products in the pores appeared after impregnation.
