Experimental and Investigation of Hybrid Fiber Reinforced ...

2016-9-9  We in ancient time fibers are used as reinforcements. In mortars horse hair is used and in mud, bricks straw is used. In 1950’s fiber reinforced concrete got great importance. By 1960’s fibers such as steel, glass, synthetic fibers such as polypropylene fibers, polyolefin fibers has got great importance. Fibers have great role to control cracking due to plastic shrinkage and due to drying shrinkage. Fibers such as polypropylene when added to concrete reduce the compressive strength, but increases both split tensile strength and flexural strength. They are more porous compared to the plain concrete.
