现场混凝土强度“钻芯—回弹”综合推定

A combined calculation method used in core-rebound of in-situ concrete strength

提出了一种给定置信度下现场混凝土强度检测推定方法 ,该方法充分利用现场得到回弹数据 ,减少钻芯量 ,从而降低了对结构的破坏。利用该方法可对现场混凝土强度进行高置信度、高精度的推定。

A calculated method of in-situ concrete strength tested in the condition of known credibility is presented in this paper.This method can make full use of rebound data and reduce number of cores to make it possible to lessen the damage of structure.By means of this method,the high-crediabe and high-precision value of in-situ strength can be obtained.
