Underwater concreting is one of the oldest methods of placing concrete under the water for the construction of submerged structures like harbors, bridges, aqueducts and other similar structures. From the literatures, it is found that very few works has been done for promoting the underwater concrete (UWC) at present scenario. There is a global need for preparing the UWC which should have properties to suit the current requirements to withstand environmental needs, strength, anti-washout properties, quick setting and also to have bonding properties with existing old concretes for the repairing purposes. Keeping all these things in mind, 15 formulations comprising of few bio-materials with mineral admixtures are proposed in this paper. Necessary critical tests, especially needed for evaluating the UWC for required durability purposes, are discussed in detail.
