초록

폴리머-시멘트 모르타르의 강도와 내구성에 대하여 검토하였다. 폴리머-혼화제로서 styrene-butadiene rubber(SBR) 라텍스, ethylene-vinyl acetate(EVA) 에멀젼 및 polyacrylic ester(PAE) 에멀젼을 사용하고, 폴린머-시멘트비를 다양하게 변화시켜(5, 10, 15, 20 wt%) 공시체를 제작하였다. 내구성의 평가시험으로는 동결융해시험, 내산성시험 및 내열성 시험을 수행하였다. 폴리머-시멘트 모르타르의 내동해성은 폴리머-시멘트비가 증가될수록 현저히 향상되었으나 내산성과 내열성은 저하되었다. SBR 폴리머-시멘트 모르타르의 강도(압축 및 휨강도)는 폴리머-시멘트비가 증가될수록 향상되었으나 EVA 및 PAE 폴리머-시멘트 모르타르는 폴리머-시멘트비 l0wt%에서 최대치를 나타내었다.

The strength and durability of polymer-cement mortars were investigated. The specimens of polymer-cement mortar were prepared by using styrene-butadiene rubber(SBR) latex, ethylene-vinyl acetate(EVA) emulsion and polyacrylic ester(PAE) emulsion with various polymer-cement ratios(5, 10, 15, 20wt%). For the evaluation of durability of polymer-cement mortars, freezing-thawing, acid resistance and heat resistance tests were conducted. With an increase of polymer-cement ratio, the frost resistance of polymer-cement mortars was greatly improved, but acid and heat resistance were deteriorated. The compressive and flexural strengths of SBR polymer-cement mortars were improved with an increase of polymer-cement ratio, whereas those of EVA and PAE polymer-cement mortars reached maximum value at polymer-cement ratio of l0wt%.
