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。

Compared with ordinary concrete, the volume ratio of fiber of irreplaceable ordinary concrete is between 1% and 2%. The tensile strength, flexural strength, shear strength and compressive strength of irreplaceable ordinary concrete are increased by 40%-80%, 60%-120% and 50%-100%, respectively. The increase of compressive strength is relatively small, generally between 0-25%, but the compressive toughness is greatly improved. Steel fiber reinforced concrete (SFRC) is a new kind of mojulj.37ix.com.cnpeidianfb.37ix.com.cnweilan.37ix.com.cntuoliutacc.37ix.com.cnjiaqiaob.37ix.co

m.cnchuweiji.37ix.com.cnmultiphase composite material formed by mixing short steel fibers with random distribution in ordinary concrete. These randomly distributed steel fibers can effectively hinder the expansion of micro-cracks and the formation of macro-cracks in concrete, significantly improve the tensile, flexural, impact and fatigue properties of concrete, and have good ductility. Steel fiber has very reliable performance and characteristics, so it is very common in the application of concrete. Because of its unique characteristics, such as strengthening the tensile properties of concrete, it has become a popular fiber product. It can be said that steel fiber reinforced concrete greatly improves the performance of concrete itself and makes concrete more solid.
