Abstract
In this study, the behavior of the recycled plastic, glass and rubber tire as partial replacement of coarse aggregate in concrete have been investigated. Polyethylene terephthalate (PET) bottles, one of the waste plastic types, broken glass of bottles and rubber tires are used for these purposes. The reason to choose these to transfer the recycles materials into valuable product and to solve the problem of dumping the tons of plastic waste, broken glass and rickshaw tires. In this study compressive strength of cylinder concrete specimens were carried out at 7 and 28 days curing. Six concrete mixes have been studied, those are—reference specimens with no recycled material (CS0), specimens with 15% plastic (CSP15), specimens with 15% (CSR15) and 30% (CSR30) tire, specimens with 15% (CSG15) and 30% (CSG30) glass. Total 24 cylindrical specimen of 8”x4” were tested for compressive strength. The order of compressive strength was CS0 > CSG30 > CSG15 > CSR15 > CSR30 > CSP15. The Study found that compressive strength of concrete mix decreases with the increase of plastic and rubber content. However, compressive strength of concrete increases with the increase of glass content. Plastic material have low bonding with cement in concrete and perform poorly. On contrary, glass works very well with concrete and compressive strength of concrete reduces with the increase of rubber content.
Highlights
Concrete is widely used construction material around the world
This study aims at examining the effect of recycled plastic, broken glass and rickshaw tire in concrete as coarse aggregate through compressive strength test for the better understanding of the behavior of those recycled materials in concrete mix
The state of the art of this study is to provide a comparative study of the partial replacements of coarse aggregate by waste plastic, broken glass and rubber tire in concrete mix in terms of compressive strength and investigate their feasibility
Summary
Concrete is widely used construction material around the world. Utilizing waste and recycled materials in concrete mixes draw greater attention to treat and manage solid waste generated through industry and municipal sewer now-a-days. Around 65%-85% of concrete volume contains coarse aggregate and they provide strength, durability, workability and stability. Stone chips, crushed stone and brick chips are used as coarse aggregate in concrete. Usage of waste materials in concrete along with conventional aggregates can solve waste materials disposal problem and provide lighter weight where low compressive strength concrete can serve the needs. This study aims at examining the effect of recycled plastic, broken glass and rickshaw tire in concrete as coarse aggregate through compressive strength test for the better understanding of the behavior of those recycled materials in concrete mix
