Strength Properties and Pore Structure of Epoxy-Modified Mortars under Steam and Steam/Heat Combined Curing

증기 및 가열 조합양생에 의한 에폭시수지 혼입 모르타르의 강도 및 세공구조

The purpose of present study is to examine the application of effective curing to hardener-free epoxy-modified mortars. The epoxy-modified mortars are prepared with polymer-cement ratios, subjected to two types of curing conditions, and tested for compressive, flexural and tensile strengths. As a result, hardener-free epoxy-modified mortars with steam curing is markedly improved with increasing air-dry curing period. High strength development of the epoxy-modified mortars may be achieved by the dense microstructure by cement and the hardener of the epoxy resin in the mortars.
