【摘要】 通过混凝土试件静态轴向拉伸试验 ,测定了其拉伸应力与应变全曲线。试验中观察了混凝土试件的表面开裂、裂缝扩展和试件断裂的全过程 ,并给出了混凝土的弹性、强度和变形等主要力学性能指标更多还原

【Abstract】 Based on the test of static tension of concrete, the variation of stress and strain was accurately measured and the whole developing process from initial appearance of cracks at the concrete surface, their extpansions, to utmost fracture of specimen, was detailedly observed. The main mechanic parameters of concrete, such as elasticity, strength, strain etc., are given.更多还原
