Geopolymer concrete, a way for green construction and sustainable urban development

Due to its unique qualities, concrete is the second most extensively utilized material in the construction sector after water. However, the Portland cement manufacturing method has significant downsides, as one ton of Portland cement produces approximately one ton of carbon dioxide. As a result, it appears that an alternative to Portland cement is required. The notion of "waste-free" development and the manufacturing of new materials with a lower environmental impact than the priorities, on the other hand, will be the aims of future cities' sustainable development. To continue developing environmentally friendly materials, it is vital to understand the environmental stimuli of new materials as well as assess the environmental effects of traditional building materials. Geopolymer has recently gained popularity as a sustainable, environmentally acceptable substance that can be used instead of Portland cement. Geopolymers are ceramic-like materials with three-dimensional poly-compact structures that are made by chemically activating aluminum and silica-containing solids at low temperatures. Trash or by-products from industry can be used to make geopolymer concrete for use in building, such as coal combustion ash, smelting furnace slag, construction waste, or agricultural waste such as rice paddy. The purpose of this article is to look at the viability of using geopolymer technology in sustainable materials for sustainable urban development in order to reduce pollution and analyze the life cycle. Based on research findings, geopolymer concretes have much better mechanical and chemical quality and also much less energy consumption than conventional concrete and have significant environmental benefits.
