A Review of Properties of Geopolymer Concrete

The growing need for concrete around the world has led to both more concrete being made and more of it being used. Carbon dioxide is released into the atmosphere when regular Portland cement is made, which contributes to global warming (OPC). because concrete that is good for the environment needs new kinds of binders. Using different binders could cut down on the energy needed to make traditional concrete and the amount of greenhouse gases it gives off. Portland cement puts out more carbon dioxide into the air than geopolymer. Geopolymer is an inorganic alumino-silicate polymer that is made without cement or water. Geopolymers are glues made from solid alumino-silicate and an extremely alkaline activating solution. Geopolymers can be made from things like fly ash and clay, which both have alumina and silica in them. In the last few decades, geopolymers have become a more popular alternative to Portland cement because they are more sustainable, durable, and long-lasting than Portland cement. Geopolymer concrete looks nice and lasts a long time. The building gets stronger, which makes the number of cracks and breaks go down. This paper makes geopolymer mortar and concrete last longer, be easier to use, and be used in more places. Workability and strength are both affected by the way and temperature of curing, as well as by the shape of the aggregate, its strengths, its moisture content, how it is prepared, and how it is graded. Other things that can make a difference are the shape, strength, preparation, and grading of the aggregate.
