초록

본 연구에서는 2015년 가을철 실제 시공중인 고층 아파트를 대상으로 1중 백색 버블시트로 타설된 콘크리트의 표면을 덮어주는 버블시트 피복양생 공법과 표면을 노출한 채로 양생없이 유지하는 표면노출 방법간을 비교하여 소성 및 건조수축균열의 저감정도를 분석하였다. 실험 결과, 버블시트를 시공하였을 경우, 수화열 및 적산온도는 표면노출보다 약간 높았고, 바닥 균열의 갯수, 길이, 최대 균열폭, 균열 면적 모두 현저하게 적은 값이 측정되었다. 따라서 가을철 버블시트를 타설된 콘크리트 표면에 적용 할 경우에는 소성 및 건조수축균열을 획기적으로 방지할 수 있는 효과적인 표면피복 양생공법인 것으로 판단되었다.

In this research, the performance of surface covering technique using a white-colored bubble sheet on reducing the cracking due to the plastic, and drying shrinkages for high rise building construction were evaluated by comparing the exposed surface without any surface treatment. From the results of the experiment conducted during fall season, desired results of decreased numbers, length, maximum width, and area of cracking were obtained without a significant difference on heat of hydration and cumulative temperature. Therefore, it is considered that the surface covering technique using bubble sheet is an appropriate method for preventing plastic and drying shrinkage cracking at fall season concrete construction.
