본 연구에서는 타일 하자 저감을 위해 시공 프로세스를 보완한 타일 모듈을 제작하였다. 타일 모듈은 떠붙임 시멘트 모르타르, 메쉬, 콘크리트로 구성되었다. 하자 발생 저감 가능성을 검토하기 위해 동결융해 시험 전후의 표면상태와 질량 변화율 실험을 실시하였으며 부착강도를 측정하였다. 그 결과, 알루미늄(A) 메쉬는 수중 환경에서, 강철(S) 메쉬는 기중 환경에서 열수축-팽창에 의한 하자가 상대적으로 다수 발생하였고, 메쉬의 크기가 작을수록 부착강도가 상승하는 경향을 보였다.

Abstract ▼ AI-Helper

The objective of this research was to engineer a tile module that could efficiently curtail the incidence of tile defects during the construction phase. To assess the potential diminution in defect manifestation, we executed experiments centered on surface condition, the variation in mass before and after the freeze-thaw test, and adhesive strength. Our findings demonstrated that thermal contraction and expansion induced a relatively escalated frequency of defects in the underwater setting for the aluminum mesh, while the steel mesh saw a higher defect incidence in the air environment. Additionally, it was noted that the adhesive strength exhibited a trend towards augmentation as the mesh size dwindled. Collectively, these results suggest that the employment of smaller mesh sizes can foster improved adhesive strength, consequently diminishing tile defects. Further exploration and development of the tile module, informed by these insights, can substantially enhance the efficacy of the construction process.
