REKHA DEVI , S. K. SHARMA AND HIMMI GUPTA M. E. (CTM), Civil Engineering, NITTTR, Chandigarh, India Professor,  Assistent Professor, Civil engineering Department, NITTTR, Chandigarh, India Email: sanjaysharmanitttr@gmail.com Abstract: 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 stren...

As a whole, the study main concern is the environment and the construction and building technology to enhance natural world as well as building materials. In view to provide new knowledge to the contractors and developers on how to improve the construction industry methods and services by using coconut shells and to sustain good product performance and meet recycling goals, there is need to design a technical specification of concrete using coconut shell as aggregates that will meet the Indian standard requirements in order to help...
