【摘要】 为了改进混凝土强度检测方法,本文对一种新型的检测方法:多次横向劈拉法进行了试验和研究。经试验分析得出:混凝土圆柱体的名义劈拉强度与混凝土的抗压强度有很好的相关性;相比传统的芯样轴压法,多次横向劈拉法可以更准确、便捷地判定混凝土材性。文章同时通过分析建立了劈拉强度和抗压强度的换算关系式。更多还原

【Abstract】 To improve the testing of concrete strength,the multiple splitting method was studied in this paper.Based on the study of the experiment,nominal transverse splitting strength of concrete cylinder is well correlated to the concrete cube strength and the multiple transverse splitting method is more accurate and convenient than the conventional axial compression method to determine the performance of concrete.Besides,the equation between splitting strength and compressive strength is deprived through the study.更多还原
