In the present paper, fly ash (no other solid material was used) with highly alkaline solutions is described. These solutions, made with NaOH, Na2Sio3.This paper, report on the study of the processing of geopolymer using fly ash and alkaline activator with geopolymerization process. The factors that influence flexural strength such as different curing condition. The fly ash, fine aggregate with replacement of foundry sand, coarse aggregats and alkaline solution were is used to make geopolymer concrete. The foundry sand is replaced by normal sand in different amount. The main purpose of replacement of foundry sand in to utilize waste by product and save environment also to see the effect on proprety of geopolymer concrete. The flexural strength is carriedout by UT machine at 7 and 28 days.
