Geopolymer concrete has recently emerged as a new eco-friendly green concrete with the potential to replace Portland cement and also utilizes copiously available waste by products that are disposed. Geopolymer concrete is a long chain inorganic molecule, formed by reacting aluminate and silicate minerals with an alkaline activator solution. The geopolymer concrete mix is prepared by using activator solution which depends on molarity of sodium hydroxide concentration. In this research, 10M sodium hydroxide solution along with sodium silicate is employed. The higher demand and scarcity of river sand, due to which various acts and legislation opposing illegal dredging and trading of river sand are framed. The ultimate objective of this research is assessing the strength properties (compressive strength, split tensile strength, and flexural strength) and durability properties (acid attack, sulphate attack, and chloride attack) of geopolymer concrete, with the view on replacing cement and river sand with economic alternative materials. The cement is entirely replaced with fly ash (80%), GGBS (20%) and river sand is partially replaced with foundry sand to produce green concrete. © BEIESP.
