超声回弹综合法检测墙体材料的强度

Strength Measurement of Wall Board Material by the Combination of Ultrasonic and Rebound Method

用超声回弹综合法对混凝土空心砌块、实心粘土砖和空心粘土砖强度进行检测并拟合曲线，检测精度在±１０％左右。

It is important to measure the strength of wall board material. By using ultrasonic and rebound method, curves of strength for hollow concrete block, solid brick and hollow brick are drafted, and experiments in laboratory and sampling inspection in site are made. The relative error is about 10%, so it has certain application value.
