Fiber Reinforced Concrete is a composite material consisting of fibrous material which increases its structural integrity. It includes mixtures of cement, mortar or concrete and discontinuous, discrete, uniformly dispersed suitable fibers. Fibers are usually used in concrete to control cracking due to plastic shrinkage and to drying shrinkage. They also reduce the permeability of concrete and thus reduce the bleeding of water.
Fibers reinforced concrete may be useful where high tensile strength and reduced cracking are desirable or when conventional reinforcement cannot be placed It improves the impact strength of concrete, limits the crack growth and leads to a greater strain capacity of the composite material For industrial projects, macro-synthetic fibers are used to improve concrete’s durability. Made from synthetic materials, these fibers are long and thick in size and may be used as a replacement for bar or fabric reinforcement Adding fibers to the concrete will improve its freeze-thaw resistance and help keep the concrete strong and attractive for extended periods. Improve mix cohesion, improving pumpability over long distances Increase resistance to plastic shrinkage during curing Minimizes steel reinforcement requirements Controls the crack widths tightly, thus improving durability Reduces segregation and bleed-water FRC, toughness is about 10 to 40 times that of plain concrete The addition of fibers increases fatigue strength Fibers increase the shear capacity of reinforced concrete beams.
Durability to aesthetics fiber-reinforced concrete can add benefits to your project. Fiber-reinforced concrete has been rapidly growing throughout the building industry since contractors and homeowners started to recognize its many benefits. Fibre Reinforced Concrete is gaining an increasing interest among the concrete community for the reduced construction time and labor costs. Besides cost issues, quality matters are of paramount importance for construction and fiber-reinforced concrete also fulfills these requirements.
