                鋼纖維的韌性

                無可替代普通混凝土的纖維體積率在1%—2%之間,較之普通混凝土,抗拉強度提高40%—80%,抗彎強度提高60%—120%,抗剪強度提高50%一100%,抗壓強度提高幅度較小,一般在0—25%之間,但抗壓韌性卻大幅度提高。   鋼纖維混凝土是在普通混凝土中摻入亂向分布的短鋼纖維所形成的一種新型的多相復合材料。這些亂向分布的鋼纖維能夠有效地阻礙混凝土內部微裂縫的擴展及宏觀裂縫的形成,顯著地改善了混凝土的抗拉、抗彎、抗沖擊及抗疲勞性能,具有較好的延性。鋼纖維有著非??煽康男阅芎吞攸c,所以在混凝土的應用中可謂是十分的普遍。因為它獨特的一些特點,比如說增強了混凝土的抗拉等特性,才讓它成為了倍受歡迎的纖維產品??梢哉f,鋼纖維混凝土大大的提升了混凝土本身的性能,讓混凝土更加的堅固。 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.
