| 钢纤维混凝土的基本理论是在纤维中增强塑料,纤维增强金属的基础上运用于发展起来的.由于钢纤维很凝土组成与结构的多相、多组分和非匀质性,加以钢纤维的“乱向”与“短”的特征,它比纤维增强塑料或增强金属要复杂得多,如何使增强机理能充分体现其自身特性,仍在不断争论、完善和发展之中. The basic theory of steel fiber reinforced concrete is developed on the basis of reinforcing plastics in fibers and reinforcing metals. Due to the heterogeneity, multi-component and non-homogeneity of the composition and structure of steel fibers, and the "disorder" and "short" characteristics of steel fibers, it is much more complex than that of fiber reinforced plastics or reinforcing metals. How to make the reinforcing mechanism fully reflect its own characteristics? Sex is still being debated, perfected and developed. 钢纤维混凝土主要目的祇是为了与混凝土中之水泥、砂、碎石好好做结合而已,而有好的结合自然就有好的结果及效能.钢纤维混凝土配合比设计的目的是将其组成金属,即钢纤维、水泥、水、粗细集料及外掺剂合理配合,使配制的钢纤维混凝土能够最大限度的满足施工和工程使用要求.使配制的钢纤维混凝土有较好的和易性,方便和满足施工要求.充分发挥钢纤维混凝土的特点,合理确定钢纤维及水泥用量,最大限度地降低工程成本.钢纤维的最大特点是既要保证良好的抗拉强度、断后伸长率、断面收缩率,对冶炼过程控制有严格要求. The main purpose of steel fiber reinforced concrete is only to make good combination with cement, sand and gravel in concrete, and good combination will naturally have good results and effects. The purpose of mix proportion design of steel fiber reinforced concrete is to mix metal, i.e. steel fiber, www.e-tour.com.cnwww.leierda88.cnwww.kskeber.cnwww.cclyw.cncement, water, coarse and fine www.omrongz.com.cnwww.westpump.com.cnaggregate and admixture reasonably, so that the steel fiber reinforced concrete can meet the construction to the maximum extent. To make the steel fiber reinforced concrete have better workability, convenience and meet the construction requirements. Give full play to the characteristics of steel fiber reinforced concrete, reasonably determine the amount of steel fiber and cement, and minimize the project cost. The greatest feature of steel fiber is to ensure good tensile strength, elongation after breaking, section shrinkage, and strict requirements for smelting process control. |
