Conventional methods of concrete reinforcing including wire mesh and rebar, are only working within a single plane. What is more, these methods does little reinforcement to outside zones where spalling is common at the joints and edges. Their primary function is to hold the floor slab together after the first small hairline cracks propagating to lager fractures. To some extent, it maintains "structural integrity".
In contract to rebar, steel fibers makes difference in controlling cracks, lowering the possibility of maintenance and saving your budget.
Strengthen the initial crack strength;
High fiber counts intercepting micro-cracks and preventing crack propagation by limiting tensile strength;
Uniform distribution of steel fiber throughout the matric reinforce isotropically ensures no weak plane for a crack to follow;
Flexural strength allows for a thinner slab, about 25% thinner than conventional methods.
