    What Are The Pros And Cons Of Fiber Mesh Concrete

    fiber mesh concrete bleeds more evenly than plain concrete. as a result, you will not experience a puddling effect. fiber mesh concrete will look more like a wet sheen. gives the concrete surface a higher impact resistance. fiber mesh concrete reduces the total crack void structure. this will give the concrete a greater shock-absorbing quality.

    Fibre Reinforced Concrete - What You Need To Know Before

    fibre reinforced concrete has a higher flexural strength than that of unreinforced concrete and concrete reinforced with welded wire fabric. but unlike conventional reinforcement – which strengthens in one or possibly two directions – steel fibres reinforce iso tropically, greatly improving the concrete’s resistance to cracking, fragmentation, spalling and fatigue.
