A Review on Eco-Green Geopolymer Concrete

Concrete is the most widely used building material in the world because of its versatile application. The essential ingredient of concrete is Portland cement, which is not considered an environmentally friendly material. The production of Portland cement not only uses up a considerable amount of energy but also emits a substantial amount of CO2. The production and use of alternative materials, such as geopolymer, represents a great opportunity to ensure greater sustainability in the construction sector. In order to reduce the environmental impact due to cement production, it is necessary to develop a new type of binder. In this respect, the geopolymer technology proposed by Davidovits (1978) is one of the revolutionary developments resulting in a low-cost and greener substitute for Portland cement. Geopolymer concrete is an innovative binder material and is produced by totally replacing Portland cement. It is an excellent alternative construction material to the existing plain cement concrete. In the present age the waste generated from industries is the huge concern for the environment, health, and cause for land filling. Recycling of such wastes and using them in construction materials appears to be viable solution not only to the pollution problem but also an economical option in construction. In this paper, the approach for development of new construction material in geopolymer concrete using industrial waste to provide a potential sustainable source will be reviewed from the present study.
