Comparative technological advantage and economic advantage of steel fiber

The technical advantages of steel fiber: pull higher bending, shear resistance and impermeability. Low shrinkage rate, can effectively prevent the shrinkage crack. To increase the impact of structural products, high fracture toughness. Good workability, uniform distribution in concrete and effective, no caking, no bare. Advantage: in the economic steel fiber under the same intensity can be reduced to save the amount of concrete. Can replace or partially replace reinforcement. Can shorten the construction period, large engineering is specially suitable for the continuous fast pouring of concrete. Steel fiber concrete and ordinary concrete the same mixing and construction, need not add equipment. Product life extension, high performance to price ratio, and obvious social benefit.
