비파괴시험법에 의한 고강도콘크리트의 압축강도 추정

Abstract

An experimental study for the compressive strength of high strength concrete was carried out in the range of design strengths between 240kg/cm^2 ~ 800kg/cm^2 to evalute the relationship between the destructive and non-destructive measuring. the age to check the strength had been chosen, as usual, as28 days. the rebound hammer test and the ultrasonic pulse velocity test were performed as a non-destructive measuring methods. In this correlations analysis for the test results, some experimental equation for the compressive strength were proposed.
