                鋼纖維混凝土是在混凝土中摻入鋼纖維而改善性能的復合材料。它具有普通鋼筋混凝土所沒有的許多優良品質:如抗拉強度、抗彎強度、抗裂強度、韌性或抗沖擊性能都可獲得改善。 Steel fiber reinforced concrete is mixed with steel fiber in concrete and improve the performance of composite materials. It has a lot of ordinary reinforced concrete have no good quality, such as tensile strength, bending strength and crack resistance strength, toughness and shock resistance can be improve. 混凝土的缺點之一是抗拉強度甚小,僅為1.5~3.0MPa,而鋼材則可達到400~1000MPa;混凝土的第二個缺點是抗拉斷裂應變值很小,在10-4間,而鋼材則在10-1間;混凝土的第三個缺點是因以上兩個缺點的結果,及混凝土呈脆性,能量吸收小,抗沖擊性能差,易發生裂縫。由于混凝土本質上的缺陷,使混凝土這種廉價材料在某些領域應用受液壓鋼壩  到限制。鋼纖維的出現使混凝土的這些缺陷得到大大改善,也使混凝土的某些性能指標改變數倍之多。 One disadvantage of concrete is the tensile strength is very small, only 1.5 ~ 3.0 MPa, while steel can reach 400 ~ 1000 MPa; A second drawback of a concrete is tensile strain value is very small, between 10-4, while steel between 10-1; Concrete of the third disadvantage is that because of the drawback of the above two results, and the concrete is brittle, small energy absorption, shock resistance is poor, prone to fracture. Due to the defects of concrete in nature, makes concrete the cheap material application in some fields is restricted. The defects of the appearance of the steel fiber reinforced concrete have been improved greatly, and makes concrete some performance index change several times as much.
