Abstract

Waste tire is increasingly becoming an environmental, health, and aesthetic problem. Used tires are of category of waste whose recycling is extensively difficult because of highly complex structure, the diverse composition of the raw material. Concrete is a versatile construction material due to easy to fabrication, locally available material, and high mechanical strength. The use of waste tires as a concrete additive is a possible disposal solution. Rubberized concrete may thus contribute in sustainable construction by use of industrial waste, minimizing the natural resources and produce a more efficient material. In this paper experimental investigation is carried out to evaluate the flexural strength, compressive strength, abrasion resistance and carbonation of concrete containing waste rubber tire fibers as partial replacement of fine aggregates. Fibers from mechanical grinding of used rubber tire have been incorporated with three water–binder ratio and six levels of rubber fibers contents (0-25%). It has also been shown that with increasing replacement level of rubber fibers, flexural strength and abrasion resistance is increased. Further, it has been also observed that compressive strength and carbonation depth changes with the increasing of the replacement level of waste rubber content.
