修正系数法和修正量法在混凝土回弹法测强的差异性分析

Analysis of the Difference between the Modified Coefficient Method and the Modified Quantity Method in the Strength Measurement of Concrete by Rebound Method

本文通过试验的方法分别采用修正系数法和修正量法来修正回弹法检测混凝土强度,经修正量法修正后的回弹法检测混凝土强度,比经修正系数法修正后的回弹法检测混凝土强度的相对误差更小。结果证明采用修正量法更合理。

In this paper,both the modified coefficient method and the modified quantity method are adopted respectively to revise the concrete strength measurement by rebound method.The relative error of the rebound method corrected by the modified quantity method to test the concrete strength is smaller than that of the rebound method corrected by the modified coefficient method..The result proves that the modified quantity method is more reasonable.
