考虑混凝土含水率在综合法测强中的应用研究

Applying Study on Water Content in Ultrasonic-Rebound Method for Concrete Strength Measurement

依据混凝土强度检测中所取得的1300多组的有效检测数据,分析了考虑混凝土含水率对混凝土综合法测强曲线的影响,并建立了考虑含水率与不考虑含水率的综合测强曲线,对两类曲线的回归误差进行了分析。最后,利用实际工程中的检测数据对两种测强曲线进行了验证对比,结果表明考虑含水率的综合测强曲线具有更高的检测精度。

Based on the total more than 1,300 groups of efficient test data acquired from concrete strength measurement, the in- fluence of toater content on concrete ultrasonic-rebound curve is analyzed and the concrete uhrasonic-rebound curves considering the water content or not are established, the regression error of two kinds of curve is analyzed and contrasted. At last, the actual engineering test data are utilized to validate that the ultrasonic-rebound curve comprising water content is more effective.
