DEVELOPMENT OF TIRE-ADDED LATEX CONCRETE

Tire-added Inter concrete (TALC) was developed to incorporate recycled tire rubber as part of concrete. Crumb rubbers from tires were used i n TALC as a substitute for fine aggregates or styrene-butadiene rubber (SBR) latex, while maintaining the same water-cement ratio. Various s tatic and dynamic strengths of TALC were measured and compared to thos e of conventional and latex-modified concrete. TALC showed higher flex ural and impact strengths than those of portland cement and latex-modi fied and rubber-added concretes. Microscopic pictures taken using the scanning electron microscope (SEM) seem to support that there is bette r bonding between crumb rubbers and portland cement paste due to latex . TALC showed potential of becoming a viable construction material to enhance brittle concrete while incorporating waste tires.
