ABSTRACT

This paper describes the effects of modified sulfur polymer content on the compressive strength and chemical resistance of Portland cement concrete with and without the modified sulfur polymer. The Portland cement concrete which contained modified sulfur had much higher strength than the Portland cement concrete without modified sulfur, workability is stabled at 55oC. Alkali tolerance test was evaluated by immersing these concrete specimens in 13 % CaCl2 solutions. In the alkali tolerance test, the resistance of Portland cement concrete with modified sulfur to CaCl2 increased compared with Portland cement concrete without modified sulfur.
