In this study, fundamental properties and change with time of cement mortar accompanied with change of solid content ratio of PC type superplasticizer were analyzed. As a result, it was clarified that the flow and air content decreased as the solid content ratio decreased, and the compressive strength increased slightly.

In previous research, the durability of the concrete was improved by filling the capillary voids with soap by the saponification reaction of the glycerin ester of the oil and the alkali of the concrete. Thus, in this research, there will be an experimental investigation on the effects of various strengths on the resistance to salt attack resistance by applying ordinary strength concrete.

In previous research team had reported that the durability of carbonation is improved by filling voids due to the saponification reaction of oil and concrete. The purpose of this study was to have experimental investigation the effect of mock-up experiment on the carbonation resistance of the waste concrete admixture.
