CO2-emission assessment of the concrete added crushed PET bottles waste

Abstract

PET-bottles generate a significant amount of waste disposal which may affect to people health and environment according to with UNEP report. The study of PET waste as a component in concrete may be the worth waste management approach for both plastic waste reduction and construction material development. The paper presents the compressive strength of specific samples by varying three levels of percentage 0%, 3% and 6% for crushed PET waste bottle waste added in concrete and propose CO₂-emission assessment model of these mixes of concrete material. All test cube samples are 28 days curing aging. Accordingly, the test results were compared to conventional concrete and waste PET mixed concrete and checked by linear regression analysis to find the correlation between the compressive strength and the percentage of PET as well as the CO₂ emission quantity of concrete mixes. This study will be a helpful part to encourage sustainable development by PET bottle waste reduction and CO₂ emission reduction concept as well as the development guide of alternative concrete material.
