超声技术在钢纤维混凝土中的试验研究

Experimental research in Steel Fiber Concrete by using Ultrasonic Technology

本文通过对一批C40钢纤维混凝土试件进行超声波检测及抗压强度的试验研究,对试验结果进行了回归分析,建立了钢纤维混凝土检测的超声波声速与抗压强度之间的关系曲线,结果表明:利用该曲线测定超声声速可推定钢纤维混凝土的强度,超声波检测方法用于钢纤维混凝土无损检测是可行和适用的。

This paper carries on the experiments and study to the steel fiber concrete samples by ultrasonic detection and compression strength, the ultrasonic strength detecting wave of ultrasonic velocity and compression strength is set up by regression analysis of the testing data. It is shown from the example that u-sing the ultrasonic velocity of this wave can forecast the compression strength of steel fiber concrete, and this method used in steel fiber concrete is simple and practical.
