Influence of nano material (TiO2) on self compacting Geo polymer concrete containing Flyash, GGBS and wollastonite

Abstract

In the modern age, concrete has become major component in construction field which results in global warming as it contains high amounts of cement. To reduce the carbon footprint and help environment, In our research, cement is elemenated and this type of concrete is called “Geo-polymer concrete”. Binders like Fly-ash, Wollastonite and Ground Granulated Blast Furnace Slag (GGBS) are used and Alkali activators like sodium hydroxide and sodium silicate are used to improve the binding properties of the concrete. Titanium oxide is used to develop self-compacting Geo-polymer concrete (SCGPC). At ambient curing conditions, Fresh and hardened properties are tested at 7, 14 and 28 days. SCGPC mixes are developed by adding Titanium oxide to mixes with and without wollastonite at 2%, 4%, 6%. To obtain the optimum results we need to perform some Fresh and as well as the Hardened properties. The fresh properties tests include slump flow. Hardened properties of the concrete include the Compressive strength and Split Tensile. The optimum test results were obtained at 4% TiO2 with and without wollastonite. There is 18–20% increase in the strength by incorporation of wollastonite.
