Abstract

The authors performed the experimental work to propose the strength prediction equation for high strength concrete based on the non-destructive test methods. The concrete specimens that the range of design compressive strength was 40~80 MPa was produced in laboratory, and then tested rebound test and ultrasonic velocity methods and also compressive test according to the Korea Standard. The test results was compared with previously equations suggested by other researcher. From the test, these traditional nondestructive methods are simple, quick, has proven to be reliable and useful method for predicting the concrete strength. The test results were compared with the previous equations and then newly proposed own equations based on the test results. The proposed equations have the suitable precision and accuracy for applying the high strength concrete structures.

저자들은 비파괴시험에 의한 고강도콘크리트의 강도 예측식을 제안하기 위하여 실험적 연구를 수행하였다. 본 연구에서 사용된 콘크리트의 설계압축강도는 40~80 MPa 범위이며, 압축공시체를 제작하여 반발경도법과 초음파 속도법으로 실험한후 KS기준에 따라 압축강도 실험을 실시하였다. 실험결과는 기존의 연구자들에 의하여 제안된 다양한 실험예측식들과 비교분석하였다. 실험결과 고강도 콘크리트에서도 반발경도법과 초음파속도법의 경우 간편성과 신뢰성에 있어 콘크리트 강도를 측정하기에 충분한 유용성을 확보한 것을 확인할 수 있었다. 기존식들과의 비교를 통하여 고강도 콘크리트에 적합한 강도예측식을 제안하였으며, 실험결과에 대한 충분한 신뢰성을 확보한 것으로 판단되어, 향후 고강도 콘크리트 구조물에 적용할 수 있을 것으로 판단된다.
