A Review of Alkali Activated Concrete Using Eco friendly Industrial Waste Materials.

Abstract

Geopolymerization is a sustainable way to make concrete by using industrial waste materials and alkaline activators. However, Geopolymer concrete often doesn't have the strength it needs, so adding nano materials can help. This review looks at how different amounts of nano materials affect the properties of geopolymer concrete. Adding nano-silica, aluminum oxide, titanium oxide, graphene, and carbon nanotubes has shown significant improvements in the concrete's strength, even when it's cured at normal temperatures. The addition of nano materials makes the concrete more dense, reducing its ability to absorb water and making it more durable against acidic conditions. Using recycled glass powder as a partial replacement in geopolymer production has also shown promising results. Adding nano-silica improves the compressive strength of geopolymer concrete, and a computer model can accurately predict the strength. The ratio of alkaline solution to binder, the concentration of the solution, and the curing temperature all affect the compressive strength of geopolymer concrete. Using waste materials in concrete production can help reduce environmental problems. Geopolymer technology can reduce greenhouse gas emissions and energy consumption, making it a promising solution for sustainable construction.
