Description

Steel fibres reinforcement is used to reinforce shotcrete in ***0s of applications throughout the world, improving the concretes ductility, flexural strength and toughness. In addition, FIBRESTEEL improves crack resistance and energy absorption, due to the presence of steel fibres throughout the concrete. Strength is also enhanced, as the steel fibres bridge any cracks, enabling the concrete to support load after failure. Long-term durability is also significantly improved as the steel fibres provide a concrete matrix with discontinuous reinforcement, able to withstand corrosive elements carried by subsurface waterinfiltration. As a result, steel fibre reinforced shotcrete can be used under conditions that would otherwise require the use of traditional and expensive support methods, including rock bolting. Where a thin layer of concrete is required, concrete with FIBRESTEEL provides a ready means of reinforcement. On rough uneven ground, a fibrous concrete coating can follow the surface contours, eliminating material waste.
