ZERO CEMENT CONCRETE WITH UPGRADED PROPERTIES

Zero Cement Concrete is an improved version of Geo-polymer Concrete wherein the thermal activation of the binding materials such as Fly Ash and Ground Granulated Blast Furnace Slag (GGBS) is done with the help of alkaline solution namely Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3).Additionally, Steel Slag was partially replaced with Blue Metal in order to make it both durable and economical. This Paper represents the experimental investigation carried by varying alkaline solution and steel slag on the mechanical and durable properties of Zero Cement Concrete.M25 Grade was chosen for 8 Molarity. The alkaline solution has been chosen in the varying ratio of 2, 2.5 and 3. Similarly Steel Slag was used in an incremental order of 20%.The performance of Geo-polymer Concrete in terms of workability was in a good range. The Prepared Samples were cured under ambient temperature. The tests were carried in accordance with Bureau of Indian Standard Codes. The Results revealed that the maximum strength was obtained at the optimum alkaline solution ratio of 2.5 and 60% replacement of Steel Slag. The Test results were far superior to the conventional M-25 Grade Concrete.
