The Study for Development on Earlier Evaluation Instrument of Strength of Concrete -An Experimental Study on Compressive Strength of Mortar Using Resistance Method-

콘크리트 강도 조기 판정기의 개발에 관한 연구 (2) 전기 저항법을 이용한 모르타르의 압축강도에 관한 실험적 연구

In this study proposed to rapid and simple test method for early decision of quality of concrete. As the this paper is experimental study for compressive strength of mortar using resistance method, the obtained results are summarized as follow ; $\circled1$ The resistance ratio was decreased as the incement of water-cement ratio $\circled2$ The compressive strength presented to the tendency of increment as resistance ratio is increaing
