PRODUCTION OF GEOPOLYMER CONCRETE FROM LOCAL MATERIALS

Thaer J. Mohammed, Ikram A. Saeed

Abstract


Geopolymer concrete is still a new construction material in Iraq and needs tremendous research to get more information about the production technique. In this study, the foreign fly ash and local fly ash produced from Baghdad south gas power plant were used with good specifications to obtain geopolymer concrete. Also, the local attapulgite clay as a pozzolan material is used to investigate the possibility for production the geopolymer concrete. The experimental results showed that the method of curing of geopolymer concrete has a significant effect on the development of compressive strength. Water immersion curing is not recommended. The heat treatment method is the best due to accelerating the reactions and formation of geopolymer concrete. The attapulgite is the best suited locally for geopolymerization in terms of compressive strength and tensile strength.
