Strenghts and Hardening Properties of Epoxy-modififed Mortars Using Wood-Tar of Wood By-Product

목재 부산물인 목타르를 활용한 에폭시수지 혼입 PMM의 강도 및 경화특성

The purpose of this study is to ascertain strengths and hardening rate of epoxy-modified mortar with wood-tar contents. The polymer-modified mortars (PMMs) using epoxy resin with wood-tar are prepared with various polymer-binder ratios of 1, 3, 5% and wood-tar contents of 0, 5, 10, 15 and 20%. The PMMs using epoxy resin are tested for compressive, flexural and tensile strengths and hardening rate of epoxy resin. As a result, the strengths and hardening rate under polymer-binder ratio 1% and wood-tar content of 5% are more excellent than those of other specimens.
