Abstract
Many applications of fly ash have been studied and employed in various fields. Thermal power stations use pulverized coal as fuel. Thus produce large amounts of fly ash as a by-product of combustion. The present analyses investigates the manufacturing process of Alkali Activated Fly Ash (AAFG) and Ground Granulated Blast Furnace Slag (GGBS) Based Coarse Aggregate using an ordinary concrete mixer and its properties are analyzed. The flexural capacity of the Reinforce Concrete (RC) beam with AAFG increases by increasing the diameter of reinforcement and decreases in the replacement AAFG beam, and the crack width decreases as an increase in the replacement of the fly ash aggregate up to 50% in concrete. The durability property of concrete blended with AAFG shows similar results to conventional concrete. From the Rapid Chloride Permeability Test (RCPT) results, it shows that AAFG concrete and conventional concrete are both in the moderate zone only.
