Abstract

Concrete is the second most product in the world, this leads to Portland cement being the largest product on a global scale. The production of Portland cement process causes the emission of carbon dioxide into the atmosphere, contributing increased pollution and exacerbating the problem of global warming. In order to contribute the reducing of greenhouse gases emission to atmosphere and to encourage the use of environmentally friendly alternatives, geopolymer-cement has been traded as an alternative to Portland cement. Geopolymer-cement is produced from industrial residues rich in silicon and aluminium. Geopolymer-cement preserving the environment in two ways, first reducing the contribution to greenhouse gas emissions and secondly benefiting from industrial waste and preserving landfills. In this paper, the fresh properties, mechanical properties and performance of geopolymer concrete were reviewed from published research by some authors. Reviewing these properties of geopolymer as an alternative to Portland cement concrete. The bottom line of this paper is that geopolymer are similar in properties or even better in some of them than Portland cement concrete, and that geopolymer represents a promising possibility and an excellent choice in the future.
