Fiber reinforced concrete

摘要

Fibre reinforced concrete comprises thin steel wire of diameter between 0.05 and 0.3 mm such as cut from recycled vehicle tyres. To avoid the problem of balling when mixing, two alternatives are suggested. The first consists of strands of fibre, which demonstrate excellent bond characteristics. The second consists of a mixture of fibre lengths and thicknesses, giving a wide distribution of 1/d ratios not exceeding 250, which has the effect of reducing balling tendency so that significant densities can be achieved.
