Experimental Investigation and Strength Characteristics of Low Calcium Fly Ash Based Geopolymer Concrete (GPC)

Abstract :

Carbon-di-Oxide emission from Cement production is the second most pollution next to automobile industry

which pollutes the atmosphere. Concrete is the second most used material next to water. Hence, it is inevitable to find
an alternative material to the existing most expensive, most resource consuming Portland Cement. Global warming, is one of the greatest environmental issues and has become a major concern during the last decade. The global warming is caused by the emission of greenhouse gases
such as CO2, Methane, Chloroflurocarbon (CFC) etc. Geopolymer concrete is a 'new' material that does not need the utilization of Portland
cement as a binder. Instead, activating the source materials such as fly ash that are rich in Silicon (Si) and Aluminum (Al) using high alkaline
liquids produces the binder required to manufacture the concrete. Hence, Greener concrete can be achieved. Aggregate ratio have been varied
with six mix ratios and14 M molarity of alkaline solution is used In this study the strength of Geopolymer Concrete trial mixes are compared
and this paper depicts about fly ash-based geopolymer concrete, aqueous solutions used mixture proportions, the manufacturing process,
and the strength parameters etc.
