Adhesion Performance Change of Positive-side Installed Rubber Asphalt Waterproof Sheet Integrated with Water-Soluble Film in Accordance to Wetness Condition

수용성 필름이 일체화된 역타설 고무 아스팔트 방수시트의 콘크리트 타설시 가수 여부에 따른 부착성능 변화 연구

Integrated water-soluble film is dissolved in the rubber asphalt waterproof sheet to secure adhesive strength on freshly cast concrete on the adhesion side of waterproofing layer on the floor slab. In addition, in order to determine whether the water in the concrete slurry can dissolve the water-soluble film sufficiently, the adhesive strength of the waterproofing sheet was compared between difference wetness condition at the upper part of the concrete specimen before the concrete casting.
