Study on Geo-polymer Concrete Under Acidic and Saline Conditions

The prominent issue in the construction business is the ecological and environmental contamination. In the construction industry, for the most part the generation of Portland cement causes the discharge of pollutants resulting in environmental contamination. We can lessen such consequences for nature by expanding the utilization of modern alternatives in our infrastructure development process. Geo-polymer concrete is one such substitute and is in effect progressively utilized on-site. To create the geo-polymer, concrete the Portland cement is completely replaced with the F-type fly-ash and alkaline fluids are utilized for the binding of materials. The alkaline liquids utilized in this examination for the polymerization are the solution of Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3). The cube samples taken are of size 100 mm x 100 mm x 100 mm for compression test, sorptivity test, carbonation depth test and 100 mm diameter x 200 mm height of cylinder are casted for splitting tensile strength and kept under acidic and saline conditions. The results are henceforth compared with conventional concrete of the same grade.
