一般水泥混凝土具有较高的抗压强度,因而广泛应用于多种构筑物中,但它的拉伸、弯曲和冲击强度与抗压强度相比,则是非常低的,因而存在易于产生裂缝、呈现脆性变形、缺乏韧性和耐冲击性能等缺陷。虽然钢筋混凝土由于配置了钢筋可以弥补混凝土抗拉强度很低的缺点,但仍不能解决混凝土抗裂性能差、早期出现裂缝等问题。 Generally, cement concrete has high compressive strength and is widely used in various structures. However, its tensile strength, bending strength, and impact strength are very low compared with its compressive strength. Therefore, cracks are easily generated and presented. Brittle deformation, lack of toughness and impact resistance and other defects. Although reinforced concrete can be used to make up for the shortcomings of low concrete tensile strength, it still cannot solve the problems of poor anti-crack performance and early cracking of concrete.
