摘要
测定了具有不同强度的轻集料混凝土和普通混凝土的断裂能 比较了轻集料混凝土和普通混凝土的断裂能与抗压强度之间的关系 结果表明 ,对于给定的强度 ,轻集料混凝土的断裂能大大低于普通混凝土的断裂能
The values of fracture energy of lightweight aggregate concrete and normal concrete with different strength levels have been measured. The relationship between the fracture energy and the compressive strength for lightweight aggregate concrete and normal concrete was compared. The results show that for certain strength, the fracture energy of lightweight aggregate concrete is much lower than that of normal concrete. It is suggested that the fracture energy of concrete may depend upon its unit weight and compressive strength or upon its dynamic modulus of elasticity.
