A Critical Review of Waste Glass Powder as an Aluminosilicate Source Material for Sustainable Geopolymer Concrete Production

Incorporation of the waste glass powder (WGP) as an aluminosilicate precursor material in the geopolymer concrete preparation has been researched for the past twenty years as an alternative to the sustainable construction material because of its significant impact on the reduction of greenhouse gases. This paper reviews the various applications of the WGP in the geopolymer matrix production as binary and ternary source material and the impact of the inclusion of WGP on the fresh and hardened characteristics of geopolymer concrete. More research articles associated with the usage of WGP in geopolymer concrete were published in the last ten years. Collective information on the WGP as an aluminosilicate source material in binary, ternary and quaternary blended geopolymer concrete is not available. This review article sums up the newest findings and developments achieved in the synthesis of geopolymer concrete containing WGP as one of the aluminosilicate source material. The study concludes that WGP could be utilized as an innovative and promising eco-friendly aluminosilicate source material to manufacture geopolymer concrete, thereby providing an environmentally eco-friendly solution for the glass and Portland cement based industries.
