混凝土抗拉强度远远低于它的抗压强度 ,粗估约为抗压强度的 1 10。混凝土结构的破坏往往是由于比抗压强度低许多的抗拉强度不足产生裂缝而破坏。水工混凝土建筑物 ,尤其是大体积混凝土和近年来在我国应用呈上升趋势的混凝土面积堆石坝 ,由于混凝土特性和结构的原因 ,极易出现裂 Concrete tensile strength is far below its compressive strength, rough estimate of about 1 10 compressive strength. Damage to concrete structures is often ruined due to insufficient cracking due to insufficient tensile strength, which is much lower than the compressive strength. Hydraulic concrete buildings, especially large-volume concrete and concrete-faced rockfill dam that has been applied in our country in recent years are prone to cracking due to the characteristics and structure of concrete
