Fibre Reinforced Concrete Need? PCC has low tensile strength, limited ductility and little resistance to cracking. PCC develops micro-cracks, even before loading. Addition of small, closely spaced and uniformly distributed fibres act as crack arresters. Fibre Reinforced Concrete is a composite material consisting of mixtures of cement, mortar or concrete and discontinuous, discrete, uniformly dispersed suitable … Read more
Fiber-Reinforced Concrete Historical Development Fibers have been used to reinforce brittle materials from time immemorial, dating back to the Egyptian and Babylonian eras, if not earlier. Straws were used to reinforce sun-baked bricks and mud-hut walls, horse hair was used to reinforce plaster, and asbestos fibers have been used to reinforce Portland cement mortars.

Concrete in Brief Properties of concrete Easily mixed, handled, transported, placed in position and compacted Segregation Separation of constituent materials of concrete Creates larger voids and reduces the durability and strength. Bleeding Water from concrete comes out of the surface Produces pores in concrete and reduces strength. Strength Compressive strength, tensile strength, flexural strength. Elasticity … Read more
