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 $55^{\circ}C$. Alkali tolerance test was evaluated by immersing these concrete specimens in 13 % $CaCl_2$ solutions. In the alkali tolerance test, the resistance of Portland cement concrete with modified sulfur to $CaCl_2$ increased compared with Portland cement concrete without modified sulfur.

일반 포틀랜드 시멘트 콘크리트에 개질 유황 고분자가 혼입되었을 때의 압축강도 및 내염기성의 영향을 일반 포틀랜드 시멘트 콘크리트와 비교하여 나타내었다. 개질 유황이 혼입된 콘크리트는 일반 콘크리트에 비해 매우 큰 강도를 나타내었고, $55^{\circ}C$에서 배합 및 혼합 작업하였을 때 안정적으로 공시체의 제작이 가능하였다. 13%의 $CaCl_2$에 개질 유황이 혼입된 콘크리트 공시체를 침지되어 내염기성을 평가하였다. 내염기성 시험에서, 개질 유황이 혼입된 콘크리트는 $CaCl_2$에 대한 저항성은 일반 콘크리트에 비해 증가하였다.
