KM/sec) 측정에 의한 압축강도(Fc; kg/cm )측정식수중양생일때 ; Fc=172Vp-451.4대기중양생일때 ; Fc=152Vp-383.9(2) 초음파속도 측정에 의한 압축강도 추정에서 빠른 초음파속도가 될수록 수중양생 압축강도가 대기중양생 압축강도보다 크게 되는 경향으로 나타났다.(3) 상관계수는 초음파속도와 압축강도와의 관계보다 초음파속도와 탄성계수와의 관계가 크게 나타났다. ; This study was aimed for offering the reference on quality control of concrete in field work with the non-destructive testing by measurement of ultrasonic pulse velocity. It was the case on the concrete manufactured at Seoul Kyong-gi Kang-won area. As result of this experiments, the relation between the compressive strength and pulse velocity(Vp:km/sec) are as following equations;Water curring:Fc=172Vp-451.4(R=0.7694)Air curring :Fc=152Vp-383.9(R=0.7503)Other relative equations are as shown in the fig. 3~11. |
