摘要
通过混凝土试件静态轴向拉伸试验,测得了高强混凝土(C50)的拉伸应力应变全曲线,与普通强度混凝土(C30)的拉伸应力应变性能作了比较,结果表明,高强混凝土拉伸应力应变全曲线与普通强度拉伸应力应变全曲线形状相似;随着混凝土的抗压强度越高,其抗拉强度越高,脆性更明显。
Static axial tension tests of 50MPa concrete specimens were conducted to obtain the tensile stress-strain relationship curves and compared them with those of 30MPa concrete.The test results indicated that high strength concrete and normal concrete has a similar tensile stress-strain relationship curves in shape,however,as the compressive strength of concrete increase,the tensile strength increase correspondingly and it becomes more brittle.
