A Study on the Estimation of Adhesive Stability of the Improved Direct Setting Method using Tile Bond for Application of Porcelain Tile under 1 percent absorptance

흡수율이 1% 이하인 자기질 타일의 타일접착제를 사용한 벽체 개량 떠붙임 공법의 부착안정성 평가 연구

This paper is to present the performance data for improved direct setting method using tile bond for application of porcelain tile under 1 percent absorptance. For this purpose, improved direct setting method type 1 & 2(tile bond curing time 0, 24H) were compared with the conventional setting methods(including direct setting method and improved pressure setting method) in the sight of the adhesive stability of porcelain tile. It tested for tiles after 14, 28days under standard condition and severe conditions. The severe conditions were water immersion, heat ageing(70℃) and freeze-thaw cycle. On the basis of test results, the adhesive strength of direct setting method was lowest for the conventional setting methods. But improved direct setting method using tile bonds(A, B) came close to the result of improved pressure setting method using tile bonds.
