施工错误混凝土测强方法试验研究

TESTING AND RESEARCH INTO CONCRETE STRENGTH DETECTION METHODS FOR POOR QUALITY ERRONEOUS CONCRETE CONSTRUCTION

采用回弹仪和新研制的恒压恒速冲击钻测强仪，可对水灰比过大、单一粒径中砂过多及单一粒径粗骨料过多的施工错误混凝土进行抗压强度检测。在试验的基础上已得出两种检测方法的测强曲线和回归方程。

The adoption of a rebound concrete strength - meter and a newly constant-pressure and constant-speed punch concrete strength detector, would be surely effective for concrete compressive strength detection.Specifically they. would make good results for those kinds of poor quality erroneous concrete construction with an excessiveness of water-cement ratio and an excessiveness of the singular medium sand grains and the singular coarse aggregate grains.Upon the bases of testing, there are two kinds of concrete strength detection method with a strength curve and a regression equation.
