Abstract

In this study, a mortar was produced using re-dispersible polymer powders that addresses the defects of aqueous polymer and improves the durability of cement mortar. Also, an attempt was made to examine the properties of polymer modified mortars using re-dispersible polymer powders by strength and durability tests between ordinary Portland cement mortars and polymer modified mortars mixed with aqueous dispersion. The test showed that strength and durability are improved considerably compared with ordinary Portland cement mortar, and the performance of aqueous polymer cement mortar was considerably improved. Accordingly, it is expected that high-quality prepackaged polymer modified mortars can be produced using re-dispersible polymer powders.

본 연구는 시멘트 복합체의 내구성을 증진시키고, 액상 폴리머의 단점을 보완할 수 있는 재유화형분말수지를 이용하여 폴리머 시멘트 모르타르를 제작하고 보통 시멘트 모르타르 및 수성 폴리머 디스퍼젼을 혼입한 폴리머 시멘트 모르타르와의 강도 및 내구성 실험을 통해 재유화형 분말수지 혼입 폴리머 시멘트 모르타르의 개질특성을 파악하고자 하였다. 실험 결과, 강도성능과 내구성이 보통 시멘트 모르타르에 비해 상당히 개선되었고, 수성 폴리머 시멘트 모르타르와의 성능 차이도 크게 좁혀진 것으로 나타났다. 따라서, 재유화형 분말 수지를 이용한 폴리머를 사용해 양질의 프리 패키지드형 폴리머 시멘트 모르타르가 생산될 것으로 기대된다.
