Abstract

The physical and mechanical properties of mortar containing copolymer lattices as chemical admixtures were investigated. Copolymer lattices used based on styrene and butyl acrylate were prepared in presence of potassium persulfate/sodium metabisulfite (KPS/NaMBS) as redox initiation system and a coemulsifier that consists of dodecyl benzene sodium sulfonate and polyvinyl alcohol (DBSS/ PVA). The results showed that the addition of copolymer lattices to mortar improves the physical and chemical properties of mortar. However, as the dosage of lattices increases, W/C ratio as well as workability increases while compressive strength and chemically combined water content decrease.
