Abstract: Steel-fibre is a kind of effective reinforced material manufactured easily and mixed by available equipment with wide source .The authors study the property of steel-fibre concrete according to the theory of fibre interval , the principle of power consumption and mixture .It has been proved that steel-fibre can improve the compressive strength , tensile strength and flexural strength of concrete very well, and improve its leak-resistance and waterproofing effectively

Key words: steel-fibre , crack-resistance , leak-resistance , waterproofing

摘要： 钢纤维是一种来源广泛、制造简单、拌制可使用现有设备的有效增强材料,笔者运用“纤维间隔说”、耗能 原理及混合法则,对钢纤维砼的性能进行了研究,实践证明:钢纤维能很好地提高砼的抗压、抗拉及抗弯初裂强 度,有效地提高砼的抗渗防水能性能.
