Experimental Investigation on Properties of Scrap Rubber Tyre as Fine Aggregate in Concrete

Abstract

In the current work, Investigation of a cube, cylinder, and beams cast of M35 grade by replacing 5,10,15 and 20 percent of rubber tyre with fine aggregate as well as 0.5%,1%,1.5%, and 2% of conplast SP430 superplasticizer were added respectively and their properties were articulated. Waste tyre concrete, also known as rubberized concrete, is an innovative and sustainable construction material that addresses both environmental concerns and the need for enhanced concrete properties. The waste tyre rubber inclusion in concrete not only decreases the environmental effect of tyre disposal but also enhances the concrete's mechanical and durability characteristics. The process of producing waste tyre concrete involves shredding and grinding waste tyres into small rubber particles, which are then mixed with cement, fine aggregates, and water to form the concrete mixture. The appropriate mix design ensures an optimal balance between rubber content and other ingredients to achieve the desired performance. From the study, it is endorsed that 10 percent of rubber tyre partially replace the fine aggregate which provides the optimum compressive strength of 36.42 N/mm2 using a superplasticizer. The rubber concrete of 10% replacement shows an improvement of 1.6 times when compared with the traditional concrete.
