Eco-sustainable Geopolymer concrete blocks production process

Brick represents one of the most used materials for the construction of buildings, but the rising demand of building materials and increased construction and demolition wastes have encouraged the development of new building materials. However, the traditional brick production causes several environmental and human health impacts, so there is a clear need of searching and replacing for more efficient and durable alternatives far beyond the limitations of the conventional brick production. The production and use of alternative materials, such as geopolymers, represents a great opportunity to ensure greater sustainability in the construction sector especially for the use of industrial wastes such as fly ash or blast furnace slag, as precursors solid. Study results have revealed that the Geopolymeric brick making process consumes less energy and involves low cost in terms of raw materials. The production of the former is compared to conventional bricks and their development which is an important step to reach better performance and environmental friendly materials. The purpose of this article is to evaluate impacts during the life cycle and describes the basic operations of the geopolymeric brick manufacturing. The analysis is performed using a life cycle approach to identify and quantify the environmental performance of the process.
