Innovative Application of Waste Tyre in Concrete Mixes

Advances in Applied Mechanics

The enormous quantity of vehicle nowadays, to some extent, undermined the environment. Increasing the number of cars indirectly produce high volume of waste tires. The presence of waste tires is a major factor that contributes to the risk of breeding places for mosquitoes, while burning tires will cause air pollution. To minimize this problem from becoming more serious, many alternatives have been implemented recently, such as the application of waste tire as a construction material. The main concept is to reduce air pollution and to produce concrete that is environmentally friendly and practical for the construction industry. Based on these objectives, this study was conducted to determine whether rubber tires can act as a concrete additive. Pieces of waste tire replaced the aggregate in the concrete mix design. The size of the tire rubber was in the range between 10 – 20 mm. The mixture of coarse aggregate replacement percentages of rubber tires by weight were 1%, 3 % and 5%. Conc...

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.

In our world, products are used and then discarded. Even when materials are recycled, the remaining refuse can create an environmental concern. An economically viable solution to this problem should include utilization of waste materials, partially replacing concrete aggregates with recycled materials that could help to combat the decreasing availability of some natural resources (natural sand) and at the same time help to utilize growing quantities of waste material like used tires. This idea has been put into practice to develop a more sustainable concrete material called rubberized concrete or crumbed rubber concrete (CRC). Experimental studies are done using the waste tire rubber in concrete in the form of crumb rubber as a replacement of fine aggregate & in the form of rubber chips as a replacement of coarse aggregate. From the literature study, the replacement percentage of fine and coarse aggregate with crumb rubber and rubber chips is identified as 25%, 50%, and 75%.A High r...

Disposal of waste tire rubber has become a major environmental issue in all parts of the world. Every year millions of tires are discarded, thrown away or buried all over the world, representing a very serious threat to the ecology. It was estimated that almost 1000 million tires end their service life every year and out of that, more than 50% are discarded to landfills or garbage without any treatment. By the year 2030, there would be 5000 million tires to be discarded on a regular basis. Tire burning, which was the easiest and cheapest method of disposal, causes serious fire hazards. Temperature in that area rises and the poisonous smoke with uncontrolled emissions of potentially harmful compounds is very dangerous to humans, animals and plants. The residue powder left after burning pollutes the soil. One of the possible solutions for the use of waste tire rubber is to incorporate into cement concrete. This paper presents an overview of some of the research published regarding the fresh and hardened properties of rubberized concrete. Studies show that there is a promising future for the use of waste tire rubber as a partial substitute for aggregate in cement concrete. It was noticed from literatures that workable concrete mixtures can be made with scrap tire rubber and it is possible to make light weight rubber aggregate concrete for some special purposes. Rubberized concrete shows high resistance to freeze-thaw, acid attack and chloride ion penetration. Use of silica fume in rubberized concrete enables to achieve high strength and high resistance to sulfate, acid and chloride environments.

Waste-Tyre rubber is one of the most significant environmental hazards worldwide. Because of the increase in auto mobile production, there is a need to properly dispose the vast amounts of used rubber tyres. Owing to the fact that the available sites for waste disposal are rapidly depleting. Hence, efforts are being made to discover the prospective use of waste-tyre rubber in construction technology. Crumb rubber is thought to be a potential material for use in concrete technology. It is considered as an alternative to the natural aggregates, used as filler in concrete matrix. Owing to lower strength, the rubberized concrete is recommended for non-load bearing structures and structural members. The main aim of the study is to identify the usage of recycled material in the concrete as it enhances the mechanical properties of concrete. As "Crumb Rubber" is also one of the solid waste which can be used in concrete by partially replacing fine aggregate. In this study "Crumb Rubber" was replaced by volume of fine aggregate as 15%,17.5%,20%,22.5%,25% volume of "Crumb Rubber" replaced fine aggregate explained by different authors in their research papers. Many tests were done by these different authors for hard concrete (i.e. Compressive strength, Flexural strength test) for M20, M25, M30 Grade of concrete. I-INTRODUCTION An estimated 1000 million tyre reach the end of their useful lives every year and 5000 million more are expected to be discarded in a regular basis by the year 2030. Up to now a small part is recycled and millions of tyre are just stockpiled, landfilled or buried. Many

Concrete is one of the most extensively used construction material in the world and the mineral aggregates used to make the concrete are a finite resource, which is fast dwindling. On the other hand, Waste tyre treatment is now a serious global threat. Waste tyre dumping, disposal of these materials or burning these tyres cause serious environmental and health problems. The public, governments and industry are all greatly interested in green environment and engineering approaches towards better sustainable development. At the same time, these studies can help to make the environment clean and minimize waste. An emerging use is the production of concrete, in which rubber tyre particles Partially replace natural coarse aggregates. One of the solutions suggested is the use of tyre rubber aggregates as additive in cement based material. Waste tyres are cut into small pellets of size matching the nominal aggregate size and are used to replace the coarse aggregate used in concrete. For comparative analysis, concrete mix of M20 grade is prepared for various concrete mixes by varying percentage replacement of mineral coarse aggregates by 4, 6, and 8 rubber aggregates and the mechanical properties of rubber concrete are compared with that of conventional concrete. Different combinations of crumb rubber with traditional coarse aggregate were evaluated based on compression strength and flexural strength tests were conducted according to Indian Standard.

Waste rubber tyre is one of the most abundant environmental hazards all over the world. Because of the increase in auto mobile production, there is a requirement of proper disposal of huge amount of used rubber tyres. Due to the fact that the presented sites for waste dumping are quickly diminishing, many countries have already banned the protection of waste-tyre rubber in disposal areas. Hence, efforts are being made to determine the future use of waste-tyre rubber in construction technology. Scrap rubber is assumed to be a possible material for use in concrete technology. It is considered as an alternative to the natural aggregates, used as filler in concrete mixture. Owing to lower strength, the rubberized concrete is recommended for non-load bearing structures and structural members. Rubber aggregates in concrete are mechanically cut to the mandatory sizes. It was effortful and was difficult to handle at the initial stages. However, all these difficulties can be easily figured out if suitable technology and machinery are available for this specific usage.

This study determines the compressive strength performance of rubber concrete and disposal of waste tyre, which consists of 0%, 10%, 20% and 30% of the selected rubber content that is mixture of 60% crumbled and 40% powdered form. The rubber particles used in the experiments are made of the recycled tire. The rubber waste is not easy to decompose even after long period of treating in landfill. Partial replacement of rubber in fine aggregate can be a way to utilize only where strength requirement is very low. Casting of cubes and beams with m30 design mix. The specimens were cured in water for required number of days before testing. Results were clear for reduction in strength with increase in rubber content.

Disposal of waste tire rubber has become one of the major environmental issues in the world. Every year millions of tires are discarded, thrown away or buried all over the world, representing a very serious threat to the ecology. It was estimated that, almost 1000 million tires end their service life every year and more than 50% are discarded without any treatment. One of the possible solutions for the use of waste tire rubber is to incorporate into cement concrete, to replace some of the natural aggregates. This paper presents the results of an experimental research to analyse the suitability of waste tire rubber as a partial substitute for natural fine aggregates in cement concrete. For the first time, three sizes of crumb rubber were mixed in definite percentages and replaced for fine aggregates from 0% to 20% in multiples of 2.5%. Tests were done to determine the mechanical properties, water absorption, resistance to sulphate attack, carbonation and porosity of these concrete samples. It was observed that the values of compressive strength, flexural tensile strength, pull-off strength and sulphate attack of rubberized concrete were lower than that of control mix; but up to a certain percentage, they gave better resistance to water absorption, and carbonation. It was concluded that there is a promising future for the use of discarded tire rubber as a partial substitute for fine aggregates in concrete, which can result in huge environmental and sustainability benefits.
