Enhancing the elasticity of Silicate Cement Stone with anionic styrene-butadiene latex particles

Abstract To address the problems of brittleness and poor elastic deformation ability of Silicate Cement stone, anionic styrene-butadiene latex particles were prepared using emulsion polymerization with styrene, liquid polybutadiene, 2-acrylamido-2-methyl-1-propanesulfonic acid, and fumaric acid as raw materials. The dispersion properties of anionic styrene-butadiene latex particles in water were investigated, as well as the elastic enhancement effect of the particles in cement. The test results show that anionic styrene-butadiene latex particles have good dispersion performance in water, is not easy to agglomerate, and can improve the fluidity of cement slurry. The elastic modulus of anionic styrene-butadiene latex particles cement stone is 43.1% and 27.8% lower than that of blank cement stone and commercially available latex particles cement stone, respectively. The finding of the mechanism analysis demonstrate that the anionic styrene-butadiene latex particles can be filled in cement stones to increase the silicate cement’s elasticity, compactness, and resistance to external stress.
