Abstract - Solid waste management has recently got a lot
of interest from the scientific community. Because of its nonbiodegradable nature, accumulating waste tyre has become a subject of interest among diverse solid waste. The majority of waste tyre rubbers are utilized as fuel in a variety of businesses, including thermal power plants, cement kilns, and brick kilns, among others. Unfortunately, this type of consumption is both environmentally unfriendly and expensive. As a result, using scrap tyre rubber in the manufacturing of concrete has been proposed as an alternate method of disposing of such trash in order to safeguard the environment. Cubes, cylinders, and beam examples were cast with shredded rubber crumbs replacing fine aggregate in proportions of 2%, 4%, 6%, 8%, and 10% by weight and compared to conventional specimens. Key Words: Solid Waste Management, Waste tyre rubber, Rubber Crumbs, Replacing Fine Aggregate
1. INTRODUCTION Aggregates are in great demand in the business sector. It is a well-known fact that most aggregates used in concrete are mined. Unfortunately, mining has a negative impact on the ecosystem by reducing the ground water table. It also disintegrates rock layers, which is the primary cause of earthquakes and landslides. Modern transportation growth resulted in a high number of cars, which resulted in a significant volume of waste tyres. The disposal of waste tyre rubbers is costly, and the ever-dwindling number of landfills leads to hoarding. Stockpiles of this non-biodegradable waste tyre rubber create a drop in the water table, resulting in draught and other disasters. Because of the combustible nature of tyres and the geometry of tyres, fires are difficult to put out, and runoff pollutes ground water. Attempts have been made in this approach to utilise rubber tyres in building in various ways. Several recent research have demonstrated that adding used rubber tyre particles to concrete improves several of the poor features of ordinary concrete, such as low tensile strength, ductility, energy absorption, shrinkage, and cracking. The use of used rubber tyres as aggregate has lately been the topic of a lot of studies across the world, although our country has done very little study in this field.

this field of research. Due to its lightweight, flexibility, energy absorption, sound and heat insulating capabilities, recycled scrap tyre rubber appears to be a promising material in the building business. Unfortunately, the use of discarded tyres in Portland cement concrete mixes, particularly for highway usage, has received little attention. Researchers have only done a limited amount of investigation into the usage of rubber tyres in ordinary concrete. Tire rubber as an aggregate in concrete is the focus of the literature on the use of tyre rubber particles in cement-based products. The majority of the studies, as noted above, have revealed a significant reduction in the mechanical qualities of concrete when tyre rubber particles are used as aggregate. Solely using coarse rubber particles has a detrimental impact on the characteristics, whereas only using fine rubber particles has a positive impact. They've been studied for a long time as a resource reutilization as an aggregate in concrete, resulting in the rubcrete mix, which may be utilised in a variety of applications and has promising results. Rubcrete produces a finished product with high mechanical qualities and is a costeffective and efficient solution to recycle waste tyres by partially or completely substituting natural aggregates. Nowadays, there is a lot of focus on the research community. Because of its non-biodegradable nature, accumulating waste tyres has become a subject of attention among the numerous solid wastes. The majority of waste tyre rubbers are utilised as fuel in a variety of businesses, including thermal power plants, cement kilns, and brick kilns, among others. This type of consumption is both environmentally unfriendly and expensive. As a result, the use of scrap tyre rubber in the production of concrete has been proposed as an environmentally friendly alternative to disposal of such trash. The samples will be tested for three days, seven days, and twenty-eight days. We'll look at the influence on fresh concrete's compressive, split tensile strength, and slump qualities, as well as the best degree of substitution to achieve the highest quality, and compare it to the test results of control specimens.
1.1 Objective Objective of this study is to look at the effects of partial fine complete replacement with scrap tyre rubber and compare the resulting conventional concrete specimens to reference examples. ISO 9001:2008 Certified Journal
