Concrete is the most consumptive material after water in the world because of its strength and durability. But the production of cement depends on natural resources and emits a huge amount of carbon dioxide into the atmosphere. For the sustainable environment and to reduce the global warming caused by the carbon dioxide emitted by the cement industry new substitutes which are eco-friendly is the need of the hour. Geopolymer concrete also is known as green concrete or cementless concrete produced by 100% replacement of cement with the waste product obtained from the industries. Geopolymer concrete uses fly ash, slag, and rice husk as a binder which is a substitute for conventional concrete. In present work, the different trail mixtures with variation in Alccofine were prepared to check the workability, compressive strength and permeability of Geopolymer concrete. Variation in content of Alccofine is done as 0%, 10%, 20%, 25% and 30%. As arccosine is an admixture which is micro-fine in its structure, so it may affect the fresh and hardened properties of Geopolymer concrete. In the study, results show that with increase in content of Alccofine up to 25% the significant increase in the compressive strength of concrete can be gained.
