Use of Waste Marble Dust and Waste Glass Powder and Bacterial Solution for Manufacture of Ecofriendly Concrete

Concrete is one of the commonly used building stones, and its production has aggravated comprehensively. This eventually has aggravated the cement production increasing the emission of greenhouse gases on enormous scale, a sensitive environmental issue in current scenario. This issue can be effectively addressed by using industrial waste like waste marble dust (WMD) for substitution of cement in concrete and waste glass powder (WGP). In this research work, cement is replaced by WMD up to 9%, and WGP is used up to 10% as a substitute of fine aggregate along with use of bacterial solution to improve post cracking behavior of concrete. The estimation of strength properties of manufactured concrete shows enhancement in strength in compression and tension. The experimental results are subjected to the regression analysis propose modified rules to estimate concrete properties. The comparison of experimental results with the equations proposed exhibits high correlation indicating efficiency of the rules proposed. The environmental impact analysis shows positive influence of WMD and WGP on environment, and results show a drastic reduction in greenhouse gas emission and particulate emission.
