摘要
基于抗压强度与抗拉强度之间存在着一定的关系原理,采用抗拉试验,对30组混凝土标准试件和4面试验墙,共720个测点进行研究,选取合理胶粘剂,保证混凝土被拉断,得到混凝土的抗拉强度,通过对试验数据的统计分析,建立了混凝土抗拉强度与抗压强度之间的线性模型,与回弹法进行比较,其相关系数、平均相对误差以及相对标准差都优于回弹法。同时,这种检测方法具有创伤面浅、面积可控的优点。实验数据可为工程应用和相关规范的制定提供参考和理论依据。抗拉法既可以作为一种新型的检测方法用于实际,也可以代替钻芯法作为一种修正方法。
Based on the principle of the correlativity in strength of compression and tension,Using the tensile strength test,studied 30 group concrete criterion specimens and 4 walls,720 test points in all, ensure that concrete was destroyed by choice proper gum. Based on the analysis of the test results, the critical linear model on the compression and tension strength of the concrete were obtained, This method compared with the rebound method, the relation coefficient and equally relative error and relative criterion error are better to the rebound method. Besides, there are the advantages of a little damage and the easy test point. The test results recommendation can provide theoretical basis and references to the practical applications and to establishment of the related criterions. The results show that tensive method not only can being a new testing method, but also can be regarded as a amend method replacing drilled core method.
