 Abstract
The aim of the research is suggesting the curing method and selection of surface-covered curing materials with the goal of achieving non-cracking concrete by applying on the actually constructed top slab of the apartment and comparing the surface covering method using single-layered white bubble sheet with the surface covering method using polyethylene film. As a result of the experiment, the single-layered white bubble sheet provided better performance of the number of floor cracking, cracking length, the maximum crack depth, and cracking area that the polyethylene film while there was no significant difference of heat of hydration and accumulative heat. Especially, the concrete area cured with single-layered white bubble sheet did not have plastic shrinkage cracking. Therefore, based on the considering the performances of insulation, cracking reduction, financial benefit, and easiness of working, it is determined that the single-layered white bubble sheet, and its application are the most desired material and technique for concrete curing method during fall.
