A Study of Fiber Reinforced Geopolymer Concrete by Using Admixer Equi Proportional Flyash and Ggbs

Abstract

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 enterprise are worldwide warming and insufficiency of creation cloth.One of the strategies for replacing concrete elements is using geo-polymer which helps in the use of very less amount of cement in concrete. Geo polymer results from the reaction of a source fabric that is wealthy in silica and alumina with alkaline liquid. It is basically cement unfastened concrete. This fabric is being studied considerably and suggests promise as a greener replacement for everyday Portland cement concrete in some programs. Research is shifting from the chemistry domain to engineering programs and commercial production of geopolymer concrete. It has been located that geo polymer concrete has desirable engineering houses with a discounted global warming potential as a consequence of the overall alternative of regular Portland cement. This project represents study at the flexural behavior of fiber bolstered Geopolymer concrete.

            In this examine, Geopolymer concrete is produced with fly ash, GGBS and sodium hydroxide and sodium silicate is used as a binder. Fly ash and GGBS are taken in identical percentage to beautify properties of concrete and the fiber used in this undertaking is polypropylene fiber (Recron 3s). For this assignment, the combination design is done for 8M and 16M awareness of sodium hydroxide. Alkaline activator solution ratio of 2.0 is selected for this investigation. The specimen of size 500x100x100mm prisms were casted of M10, M20, M30 and M40 grade of concrete and the specimens of geo-polymer concrete are cured at ambient temperature for 7days and 28 days. The cured specimens were then tested for flexural strength and high strengths are achieved.
