In uence of waste tyre fibers on strength, abrasion resistance and carbonation of concrete

Waste tire is increasingly becoming an environmental, health, and aestheticproblem. used tires are of category of waste whose recycling is extensively dicult becauseof highly complex structure, the diverse composition of the raw material. concrete is aversatile construction material due to easy fabrication, locally available material, and highmechanical strength. the use of waste tires as a concrete additive is a possible disposalsolution. rubberized concrete may thus contribute in sustainable construction by use ofindustrial waste, minimizing the natural resources and producing a more ecient material.in this paper experimental investigation is carried out to evaluate the exural strength,compressive strength, abrasion resistance and carbonation of concrete containing wasterubber tire bers as partial replacement of ne aggregates. fibers from mechanical grindingof used rubber tire have been incorporated with three water-binder ratio and six levels ofrubber bers contents (0-25%). it has also been shown that with increasing replacementlevel of rubber bers, exural strength and abrasion resistance is increased. further, ithas been also observed that compressive strength (up to 90 days) and carbonation depthchange with the increasing of the replacement level of waste rubber content.
