        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.

        In construction sites there are many cases that concrete is cured in a dry condition, without being moistured, after form have been removed. Consequently such curing condition causes cracks on concrete. In this study is to observe when applied ERCO(Emulsified Refined Cooking Oil) coating on concrete surfaces after removal of form, affects water evaporation and Shrinkage of high-strength mortar.

        In this study, natural fine aggregates(NFA) and recycled fine aggregates(RFA) was applying in the lightweight foamed concrete. To replacement of OPC, high volume blast furnace slag was used and incineration ash and recycled aggregates powder were used as alrali activator, Fundamental performances of lightweight famed concrete has been tested. Results showed that as the increase of foam conduction ratio, the strength and the density has been decreased

        This study investigates the effect of surface coating materials on the level of resistance of concrete carbonation. For the surface coating materials, paint (Pa), waste cooking oil (WCO) and waste cooking oil + paint (WCO + Pa) were prepared and applied on the surface of concrete specimens after exposure to accelerated carbonation environment for four weeks.
