| 无可替代普通混凝土的纤维体积率在1%—2%之间,较之普通混凝土,抗拉强度提高40%—80%,抗弯强度提高60%—120%,抗剪强度提高50%一100%,抗压强度提高幅度较小,一般在0—25%之间,但抗压韧性却大幅度提高。 钢纤维混凝土是在普通混凝土中掺入乱向分布的短钢纤维所形成的一种新型的多相复合材料。这些乱向分布的钢纤维能够有效地阻碍混凝土内部微裂缝的扩展及宏观裂缝的形成,显著地改善了混凝土的抗拉、抗弯、抗冲击及抗疲劳性能,具有较好的延性。钢纤维有着非常可靠的性能和特点,所以在混凝土的应用中可谓是十分的普遍。因为它独特的一些特点,比如说增强了混凝土的抗拉等特性,才让它成为了倍受欢迎的纤维产品。可以说,钢纤维混凝土大大的提升了混凝土本身的性能,让混凝土更加的坚固。 Ordinary concrete fiber volume rate between 1% - 2%, as compared with ordinary concrete, the tensile strength increased by 40% - 80%, the flexural strength increased by 60% - 120%, shear strength increased by 50% 100%, increase the compressive strength is small, generally between 0-25%, but the compressive toughness is improved to a great extent. Steel fiber reinforced concrete is mixed in ordinary concrete to the distribution of the short steel fiber formed by a new type of multiphase composite materials. These disorderly to the distribution of steel fiber can effectively prevent the expansion of the internal micro cracks of concrete and the formation of macroscopic fracture, significantly improve the concrete tensile, bending, impact and fatigue resistance, good ductility. Performance and characteristics of steel fiber has a very reliable, so in the concrete application is very common. Because of its unique features, such as enhancing the concrete such as tensile properties, just let it become a popular fibre products. Steel fiber reinforced concrete, as it were, greatly improve the performance of concrete itself, makes concrete more strong. |
