不同条件下混凝土强度无损检测方法研究及其应用

The Research and Application of the Concrete Strength Nondestructive Testing Method in Different Conditions

本文就长龄期、潮湿、粗骨粒三种条件的混凝土进行研究,发现不同条件采用的最优方法如下:在未发明新的无损检测方法时,对于长龄期混凝土的无损检测技术,超声回弹综合法是一种首选的快速测试技术;对于潮湿混凝土的无损检测技术,回弹法是一种首选的快速测试技术;对于粗骨粒混凝土的无损检测技术,超声回弹综合法配合钻取大直径芯样进行修正是一种首选的快速测试技术。

This article explores what focus on researching concrete in three conditions such as long age, moist and coarse aggregate. Found below are the optimum test methods for each condition after rigorous testing. For long age nondestructive test method, found synthetic of ultrasonic rebound test method is a quickest and most convenient testing technology.For moist concrete nondestructive test method, found rebound method is a quickest and most con- venient testing technology.For coarse aggregate nondestructive test method, found synthetic of ultrasonic rebound combining with drill a large diameter core sample correction test method is a quickest and most convenient testing technology.
