　　While trying to find a material that could potentially replace Ordinary Portland Cement (OPC) using wastes from several industries and at the same time reduce CO2 emissions from the production of OPC, scientists around the world have been researching alkali activated cements, also known as geopolymers.During the past decades, alkali-activated and blended cements have attracted strong interest worldwide due to their advantages of low energy cost, high strength and good durability.Another major incentive for further development of such cements is generated by the great quantity of annual generation of wastes, which cause a need to find new uses for them.The main raw materials used for this propose are fly ash, ground granulated blast furnace slag and metakaolin, in which activators like water glass and sodium hydroxide are used.
