WHAT IS FIBER REINFORCED CONCRETE? TYPES OF FIBERS, APPLICATIONS AND ADVANTAGES.
In conventional concrete, micro cracks are developed in concrete due to drying shrinkage and other causes like weather, temperature, insufficient curing, vibrations etc. This cracks are occur even before the loading on the slab. When the structure is loaded, this cracks will open up and start propagate which further damage the slab. The development of such micro cracks is the main reason of inelastic deformation in the concrete. This cracks makes concrete weaker. To prevent this thing, Closely spaced and uniformly dispersed fibers are added in concrete to make concrete more stronger. This addition of fibers substantially improve the static and dynamic properties of concrete. These fibers offer increased resistance to growth of crack and improves the tensile strength and durability of concrete. Fiber reinforced concrete (FRC) can be defined as composite material consisting of concrete and uniform dispersed fine fibers. The continuous meshes, woven fabrics and long wires are not con
