Flexural behavior of Alkaline solution with equiproportional fly ash and ggbs fiber reinforced geopolymer concrete

M.RAM PRAKASH1, K. RAJU

Abstract


Geopolymer concrete is a concrete with sodium hydroxide-silicate binder mechanism.It possesses the benefits of expeditious strength gain, excellent mechanical and durability properties. Manufacture of Portland cement produces large volumes of carbon dioxide and other gases. Releasing these gases causes atmospheric pollution and subsequent environmental degradation. Concrete is widely used and reliable material for construction. Some of challenges in industry are global warming and insufficiency of construction material. One of the methods for replacing concrete constituents is the use of geo-polymer which helps in using very less quantity of cement in concrete. Geopolymer results from the reaction of a source material that is rich in silica and alumina with alkaline liquid. It is essentially cement free concrete. This material is being studied extensively and shows promise as a greener substitute for ordinary Portland cement concrete in some applications. Research is shifting from the chemistry domain to engineering applications and commercial production of geopolymer concrete.This project represents study on the flexural behaviour of fiber reinforced geopolymer concrete. In this study, geopolymer concrete is produced with fly ash, GGBS and sodium hydroxide and sodium silicate is used as a binder.
