Experimental Study of Geopolymer Concrete by Addition of Nano-Silica and Steel Fiber

Geopolymer concrete is an alternative material to concrete which is characterized by long chains or networks of inorganic molecules for use in transportation infrastructure construction. It is processed from natural materials or industrial by products which significantly reduce carbon footprint and also better durability.  However, material development is still in its infancy, In this paper we discuss the mechanical properties of geopolymer concrete. In this paper effect of nano-silica and fibers M35 grade has been studied by varying the percentage of 0.5%, 1%, and 1.5% by volume of concrete. In the present study, a geopolymer concrete of M35 grade is considered and addition of nano-silica at 1%, 2% and 3% respectively and steel fiber at 0.5%, 1% and 1.5% respectively to percentage of cement for testing the compression and split tensile strength at 7th and 28th days and the durability of the fiber added concrete is checked by Electro-Chemical Corrosion Test.
