The available studies regarding utilization of waste rubber tyres in concrete provide a strong recommendation for the use of this waste as a partial replacement of fine aggregate or coarse aggregate in concrete production. This would facilitate the effective use of the solid waste, minimize the accumulation of the tyres and reduce the consumption of natural resources. In this study an attempt has been made to study the various properties necessary for the design of concrete mix replacing cement by weight with the shredded scrap rubber tyres in a systematic manner. Keywords: Shredded Scrap Tyre Rubber, Light weight Concrete, Compressive Strength, Admixture 1. Introduction Modifications of construction materials have an important bearing on the building sector. Several attempts have been therefore made in the building material industry to put to use waste material products, e.g., scrap tyres, into useful and cost effective item. Scrap tyres have been classified as a part of municipal solid waste (MSW) resulted from the increase of vehicle ownership and traffic volume. This eventually will increase consumption of tyres over time. Current practices show that residents throw it randomly in different places such as valleys, road sides, open areas, and waste dump sites in improper ways taking the means of open fire, and without consideration of risk on human health and environment. Earlier many researches related to the use of waste rubber tyre has been done in concrete by replacing coarse and fine aggregate by the waste tyre rubber material. It has been observed that rubber tyre mixed concrete mixtures showed lower unit weight compared to plain concrete and good workability. Also results of compressive and flexural strength indicated larger reduction in rubberized concrete when replacing coarse and fine aggregate. 2. Literature Review (a) Naik TR, Singh SS. (1991) [1] studied to determine constructive use options of discarded tyres. Various technologies concerning use of discarded tyres reviewed were retreading, splitting, reclaiming, combustion, pyrolysis, construction of breakwaters, erosion control structures, reefs, pavements, general construction material, etc. The experiment primarily describes the use of discarded tyres in rubberized pavements and materials. Tyre rubber can be used as an ingredient of construction materials, including impact absorbing materials. This includes use of tyres in several asphaltic application such as roofs, basements, water proofing, expansion joints, etc., elastic foundations, railroad ties, crash barriers, etc. (b) Eldin NN, Senouci AB (1994) [2] The study focused on determining the strength characteristics of rubberized concrete and examined the relationship between the size, percentage, and shape of rubber aggregate and the strength measured. Rubberized concrete was found to possess good aesthetics, acceptable workability, and a smaller unit weight than plain concrete. However, it showed low compressive and tensile strengths and lower resistance to repeated freezing and thawing cycles than that of plain concrete. (c) Pelisser F, Zavarise N, Longo TA, Bernarin AM (2011) [3] Utilization of waste vehicle tires in composite materials is an important way to consume these wastes. The strength reduction of rubberized concretes leads to prejudgment to this type of concrete. However, its lower unit weight with higher sound and heat insulation, higher impact resistance and toughness and increased ductility properties are the advantages when compared with the traditional concrete. (d) Thomas BS, Gupta RC, Mehra P, Kumar S. (2015) [4] In this study, waste tyre rubber in the form of crumb rubber was used as a partial replacement for natural fine aggregates in high strength cement concrete. Crumb rubber was replaced for fine aggregates from 0% to 20% in multiples of 2.5%. Tests were done to determine the depth of carbonation, water absorption of acid attacked specimens, compressive strength of acid attacked specimen, variation in weight of acid attacked specimen and chloride penetration of these concrete samples. From the test results it could be concluded that the high strength rubberized concrete are highly resistant to the aggressive environments. (e) Bravo m, de Brito J. (2012) [5] The aim of this paper is to explore the effect of rubber types and rubber content on mechanical properties of concrete. The compressive strength, tensile strength, flexural strength, modulus of elasticity, strain at maximum strength, and compressive stress–strain curves of RC are studied. Extensive databases used for evaluating the mechanical properties of RC include the measured compressive strength of 298 mixtures, measured tensile strength of 90 mixtures, Paper ID: ART20197684 10.21275/ART20197684 347
