Fibres for the reinforcement of concrete

Steel 1/50 fibres are designed for the micro-reinforcing of concrete.

25 to 35 kg of steel 1/50 fibres per cubic metre of concrete may be added depending on the designed characteristics of the concrete.
Natural aggregates with grain diameters up to 16 mm may be used in concretes with steel fibres. The class of concrete should be no lower than B25 and w:c quotient should be no higher than 0.6. Chemical additions which do not cause corrosion of the steel fibres may be used in order to decrease the quantity of water used.
