Abstract

In this study, it is speculated that the special admixture can be mixed with ERCO beforehand to prevent adsorption of cement and AE at the time of contamination together with water, and the change in the amount of special admixture preliminarily added to ERCO We will try to analyze the influence on normal strength mortar. As a result, the flow quantity, the air quantity, the compressive strength and the flexural strength were improved as the added amount of the special admixture was increased, and When the special admixture with the addition amount of ERCO 3% was added, the strength was rather lowered. Therefore, it was found that the optimum amount of special admixture added to ERCO was 2%.
