摘要

回弹法检测混凝土强度时经常会遇到表面潮湿或浸水混凝土,因表面潮湿或浸水混凝土表面硬度降低,采用回弹法对潮湿或浸水的混凝土进行强度检测容易产生误判,必须进行修正。通过对同一标号的干湿混凝土现场检测,所得数据进行二元对比回归分析,提出了潮湿或浸水混凝土回弹法测强的修正方法,并建立精度满足要求的回弹法检测潮湿混凝土的强度曲线方程,可全面反映混凝土强度。

Abstract

The rebound method may be used to detect the intensity of the concrete. But there would have wrong judgment when using the rebound method to detect the intensity of the moist or water-immerged concrete, because the compressive strength of the surface of the moist or water-immerged concrete is always influenced and debased. The result of the rebound method detection on the moist or water-immerged concrete compressive strength must be corrected. Firstly, the detection data getting from the present detection of the wet and dry concrete of the same grade are analyzed using the duality contrast regression. Then the influence of the moist or water-immerged concrete compressive strength on the intensity detection of the rebound method is get. Finally, the intensity curve equation of the rebound method that can meet the demands of the precision on the moist concrete is established, and the concrete compressive strength is reflected completely.
