A New Equation for the Compressive Strength. of Existing Concrete Structures by Ultrasonic Pulse Velocity Test

초음파 시험법에 의한 실존 콘크리트 구조체의 압축강도 제안식에 관한 연구

This paper concerns the new equations for the compressive strength of existing concrete structures by ultrasonic pulse velocity test. The proposed equation are as follows; fc =5255.9 - 3365.8Vp + $548.4Vp^2$ (here, $r^2$=89.7%)
