ポリマーセメントペーストを用いたシート防水密着構法に関する研究（その１）：ポリマーセメントペーストの調合が接着性および水密性に及ぼす影響

抄録

In this paper, two experiments were conducted to clarify the influence of polymer cement paste mix proportion on in-plane permeability resistance, adhesiveness and watertightness. The followings are concluded from the test results. If the quality of the underlying concrete is poor, fracture at the interface between substrate and hardened paste is likely to occur. If the paste is a softer mix proportion, adhesive failure and moisture migration are more likely to occur due to the formation of a fragile layer, presumably caused by bleeding. These problems can be improved by mixing a standard amount of polymer in this waterproofing system.
