Sustainable Building Materials - Geopolymer Concrete

Geopolymer is an alternative to concrete. It is stronger than concrete as well as being fireproof and waterproof. Its thermal retention properties can be used for insulation, minimizing temperature differences and reducing the cost of heating and cooling. Geopolymer can be used anywhere that concrete can be used.

ENGINEERING PROPERTIES OF GEOPOLYMER CONCRETE

The geopolymer paste serves to bind the coarse and fine aggregates and any un-reacted material to prepare geopolymer concrete [5, 6]. The nature of the fresh geopolymer concrete is stiff paste with high viscosity hence it tends to have low workability [5, 6]. A geopolymer mix can be timed to set either fast or slow, by adjusting the mixture
