Steel fibres in concrete

Fibers are an ideal component for use in concrete and mortar as a way to improve the possible weaknesses of these materials. Concrete fibers reduce shrinkage crack formation and crack width, while also improving energy absorption and fire resistance. Other benefits can also be seen, such as the reduction or elimination of reinforcing steel as well as improved durability.

Concrete steel fibers have countless applications in concrete construction. By reducing or replacing traditional mesh and rebar, labor costs will be reduced and construction schedules will be accelerated. Safety is improved by reducing the chance of tripping or puncturing traditional rebar. Since concrete fibers are part of the entire concrete, the rebar will not end up at the bottom of the floor slab.

Advantages of steel fiber in concrete

● Increase the load bearing capacity of concrete

● Reduction of concrete slab thickness

● Load carrying capacity is not reduced by concrete cracks (crack control)

● Increased durability

● Low maintenance costs - extended service life

● Improved bending properties

● Reduces absorption of water, chemicals etc.

● Can be used for fast-track schedules

● Easier positioning of joints (fewer joints required)

● Reduced on-site labor to manage rebar

● Reduces project costs - ensures economic design

● Improved impact and abrasion resistance

● Fibers are evenly distributed throughout the concrete (concrete tensile strength can be specified)

● Tougher surface with fewer bleed holes (expected to improve concrete quality)

● Greater savings for heavier crack control systems
