The purpose of the present study is to examine the effect of the type and volume fraction of coarse aggregate and the water-cement ratio of matrix on the confidence-limit of the compressive strength of concrete estimated by various non-destructive testing methods. Two series o...
is a non-destructive testing instrument that estimates the compressive strength of concrete without causing any damage. This instrument applies to estimation of the compressive strength of concrete structures and integrity assessment such as detection of 具体测试器、具体测试和测量员第二类型版本4,是估计混...
Properties of concrete are estimated from the various methods. The Rebound hammer test, Ultrasonic pulse velocity test are the nondestructive test used to determine the compressive strength of concrete. In this paper we have done the comparative study of ultrasonic pulse velocity test, rebound hammer...
