Performance of Polymer Modified Polypropylene Fiber Reinforced Concrete
Abstract: AbstractThe fiber reinforced concrete (FRC) is a composite material essentially consisting of conventional concrete reinforced by random dispersal of short, discontinuous and discrete fibers of specific geometry. The conventional plain concrete possesses high compressive strength, low tensile strength, poor impact strength, ductility, and little resistance to cracking and poor resistance to chemical attack. The presences of micro-cracks at the mortar aggregate interface are responsible for the inherent weakness of plain …
