Potential Pathway of using Rubber Tyre as a Fine Aggregates in Manufacture of Hollow Blocks

Abstract

Numerous risks and pollutants are present in our environment, and they are seriously expanding and polluting it. The effects of disposing of non-biodegradable waste are one example. The amount of polymeric wastes, including rubber tyres and PET bottles (Polyethylene Terephthalate), has reportedly been rising quickly in recent years. Waste rubber tyres are one of the most serious environmental hazards because of the quick rise in automobile production, which causes an accumulation of waste from used rubber tyres. Rarely are they recycled, and others are simply disposed of or piled up. Due to this, numerous initiatives have been made to recognise the untapped potential of rubber made from used tyres in new developments in civil engineering. The interesting thing about these rubber materials is that they are cut into pieces and used to replace aggregate. By using them as building materials, it also has the added advantage of conserving the naturally obtained aggregates, which are in short supply because they are used in greater quantities to make concrete. In light of this, our study will examine the use of rubber tyres to replace some of the aggregate. The performance of the hollow block produced by incorporating scraps of used rubber tyres as aggregate replacement in varying ratios is examined in this paper. Although there are many projects on replacing aggregate in concrete with rubber, this paper focuses on replacing rubber in hollow blocks. As a result, after curing for 3, 7, and 28 days, various percentages of replacement rubber are cast and tested for their compressive strength. When aggregate was substituted for rubber, the test results were noted and analysed. The findings are reached after a series of tests and discussions.
