A Comprehensive Review on Sustainable Development of Lightweight Geopolymer Concrete Using Different Environmental Wastes

Abstract

The construction industry is increasingly focusing on sustainable practices to reduce its environmental impact. Geopolymer concrete, a sustainable alternative to traditional Portland cement, is being explored for its potential to reduce carbon emissions and reliance on waste. This eco-friendly concrete uses industrial by-products like fly ash, slag, and other aluminosilicate materials, and lightweight aggregates like expanded clay, shale, or recycled materials. The review highlights the environmental benefits of lightweight geopolymer concrete, including reduced carbon footprint, energy consumption, and waste minimization. It also examines the mechanical properties of lightweight geopolymer concrete, including compressive strength, flexural strength, and splitting tensile strength. This helps the sustainable development of lightweight geopolymer concrete utilizing different environmental wastes presents a viable solution for reducing the construction industry's environmental impact
