Geopolymer Concrete: an Emerging Green Material for Modern Construction

Nowadays the environmental health is considered to be the most important topic for concern. The emission of CO2 and other harmful gases to the atmosphere become a serious problem and the root cause of environmental alteration. In other ways, the production of cement is reducing continuously due to the unavailability of resources and a large amount of carbon footprint. To overcome all these problems the low CO2 emitting and alumina silicate rich sources are used as binders instead of ordinary cement. The paper reviews all the recent and experimental works done by the researchers in order to study the physical and mechanical properties of Geopolymer Concrete with different mixtures of binders and additives introduced for increasing the strength and durability. The use of different industrial by-products in concrete development is encouraged and the workability, effects of temperature variation, use of admixture, fibers and effects of water- binder ratio for the Geopolymer Concrete are examined. Reviews indicate that the compressive strength of the Geopolymer Concrete with additional hooked end steel fibers are more than that of controlled Geopolymer Concrete mix.
