Abstract
The high contribution of the cement industry to CO2 emissions is considered as one of the major contributors of global warming.That has inspired some scientists to look for solutions to minimize its effects. A feasible source material for the geopolymer binder can be any material that is rich in silicon (Si)and aluminum(Al)in an amorphous form. The use of fly ash(FA)as part or complete substitute for Portland cement (PC) in concrete is one of the promising alternatives. Since the invention of the GP concrete by Davidovits in 1979, the complete replacement of cement has been possible. GP is a class of inorganic polymers formed by reacting silica-rich and alumina-rich solids such as FA with a high alkaline solution. A strong alkaline solution is required to activate the silicon and aluminum present in the FA and setting additives, that allows transforming glass structure partially or totally into a very compacted composite
