In this study, effects of polymer-cement (P/C) ratio, glass transition temperature (Tg); amounts of functional monomers (acrylic acid, hydroxypropyl methacrylate, ammonium polyacrylate, diacetone acrylamide) on properties of polymer cement mortar were investigated. According of the tensile test, breaking elongation (ε) and the tensile strength (δ) of polymer latex-cement composites with low P/C ratio were mainly depended on Tg, differential Tg value between layer and shell in acrylic latex (ΔTg) and the amounts of functional monomer. Additionally, at a low P/C ratio, it was found that the cross-linking rate had small effect of tensile property. It was determined that the waterproofing coatings III with a low P/C (0.12) showed the excellent tensile property when the Tg and the ΔTg of the acrylic latex were controlled at -24°Cand -20°C, respectively.

Cement-based composites were prepared from rice husk and styrene-acrylic emulsion (SAE) with semi-dry production process. The volume of SAE, the rice husk content and alkali treatment on the properties of the composites were studied. Particle-matrix bonding were observed with scanning electron microscope (SEM). The mechanical test of the rice-husk cement composites proved that SAE is an effective additive for reinforcing the composites, the mechanical properties improved significantly by alkali treatment and adding SAE. the properties can meet the requirement of the china building material standard(JC411—2007) when the content of SAE reached 3%.
