混凝土超声声速与强度和弹性模量的关系研究

The Study on Relation Between Crush Intensity and Elastic Modulus and Velocity of Ultrasonic Sound for Concrete

在超声无损检测法的基础上 ,对四种不同强度等级、不同龄期标准混凝土试块进行超声波测试 ,同时作了抗压强度和弹性模量试验 ,通过试验得出了抗压强度。

Based on the method of ultrasonic nondestructive test,the ultrasonic test,crush test and elastic modulus test of four types of the standard concrete blocks with different intensity grades and different periods were made By the test we get the function equations between crush intensity,elastic modulus and velocity of ultrasonic sound,and provide certain reference for testing concrete crush intensity and elastic modulus by using the Ultrasonic nondestructive test method
