Usage of Waste PET Bottles Replacing Fine Aggregates in Concrete with Marble Dust as Additive - A Review

PET (Polythene Terephthalete) is the most used crude material for mineral water bottles, soft drink bottles, soda bottles and other shopper materials. After usage these PET bottles becomes waste and very difficult to dispose as these are disposed by burning and so causes environmental pollution and degradation. So there is a requirement of the solution to this problem. Researchers have shown a solution for reducing these wastes and using it for concrete so that waste minimization can occur. A solution to reduce the wastage is use of PET in concrete by replacing it with fine aggregates. Most of the researchers used it as PET fibres as replacement of fine aggregates in concrete. Previous studies show that it improves the properties of concrete as strength improves. Researcher studies also show that the use of PET can be effectively done by changing its shape and size. Also marble dust increases the strength in concrete. This study focuses on use of PET as flakes in concrete by replacing it with fine aggregates from 4% to 16% and to improve the strength characteristics marble dust used as an admixture in it.
