Abstract
Copolymer emulsion lattices based on styrene (St) and butyl acrylate (BuA) was synthesized with composition ratio (5/ 5) using potassium persulfate/ sodium metabisulfite (KPS/ NaMBS) as redox initiation in the presence of a coemulsifier dodecyl benzene sodium sulfonate/ polyoxyethylene glycol monomethyl ether (DBSS/ POE). The effect of concentration of copolymer lattices on the physico-mechanical properties of mortar was investigated. The results showed that, as concentration of copolymer lattices increased, W/C ratio, setting time as well as water absorption decrease, while compressive strength increases.
