用劈裂法测定混凝土的劈裂抗拉强度已进行了多年,这种测定抗拉强度的方法是在试件的中线上(圆柱体试件为直径方向)从上下两个方向施加集中压力,使在试件中产生拉应力。这种力是弹性理论在弹性阶段的应力分析中所得到的解答。尽管劈裂法测定的抗拉强度比直接按轴向受拉试验的抗拉强度值要低,但由于这种方法简便易行,在现有混凝土试验设备(即不需增加其他设备)的情况下,通过对试验方法(垫条尺寸等)的改进,使得这种方
Splitting method has been used to measure the split tensile strength of concrete for many years. The method for determining tensile strength is to apply concentrated pressure from the upper and lower directions on the midline of the test piece (the diameter of the cylindrical test piece). Causes tensile stress in the test piece. This force is the answer to the elastic theory’s stress analysis in the elastic phase. Although the tensile strength measured by the splitting method is lower than the tensile strength value of the direct axial tensile test, this method is simple and easy to implement in the existing concrete testing equipment (ie, no additional equipment is required). Next, by improving the test method (pad size, etc.)
