The effect of bio-waste eggshell powder as a potential filler on reduction of CO2 emissions

Abstract

The eggshell is a type of bio-waste which is considered hazardous to the environment. In this study, investigated the compressive strength when using different amounts of eggshell powder (ESP), namely 5%, 10% and 15% by weight as a substitute for ordinary Portland cement (OPC). The results show that the compressive strength of ESP-5 at 7d and 28d is almost similar to ESP- 0. Meanwhile the carbon dioxide emission was though sustainable assessment analyzed. It was concluded that ESP replacement level of around 5% provides the best performance to reduces environmental pollution.
