Abstract
Polycarboxylate was synthesized and the structure of the superplasticizer was characterized by FTIR. The water reducing effect of the synthesized copolymers was studied in terms of stirring time, the surface tension of superplasticizer and the adsorption on cement particles of superplasticizier. For all the samples tested in this research, increase in stirring time caused an increase in fluidity. The surface tension of the product solution (1wt%, w/w) is 51.2536 mN/m and the maximum value of adsorption was at about 2.6 mg/g at the concentration of 6wt%.
