基于立方体试件与实体芯样试件的回弹法测强曲线研究

Based on the Standard Cube Specimens and structural entity cores to study on the detection strength curve of the rebound method

本文通过对粉煤灰混凝土浇筑成型的模拟实体模型与相应的立方体试件进行回弹法测试,分别建立了以立方体试件抗压强度、芯样试件抗压强度为因变量的回弹测强曲线,并对两种测强曲线进行了对比分析,研究结果可供混凝土强度检测参考。

For the rebound method is tested by simulating the entity to the pouring of concrete with fl y ash model and the corresponding cube specimens, to establish a separate cube compressive strength, the compressive strength of core sample for the dependent variable rebound curve, and two kinds of strength test curve are compared and analyzed. The research results can be used for detecting the strength of concrete reference.
