A Study of Composition of the Geopolymer Concrete Structure Using Silica Fume

Abstract

The usage of Portland cement in the process of concrete construction is under critical supervision due to release of enormous amount of carbon dioxide gas into the atmosphere during the production of cement. In recent times, an attempt has been made to enhance the utilization of silica fume in order to replace Portland cement partially in the concrete. Thus, Geopolymer concrete is considered to be the new material that does not require the presence of Portland cement as a binder. Instead, the source of the materials like Silica Fume that are rich in Silicon is activated by alkaline liquids in order to produce the binder. Hence, the resultant concrete will be free from Portland cement. This paper mainly presents the details of development of the process of making silica fume-based geopolymer concrete in order to avoid Portland cement partially.
