ABSTRACT
Roller Compacted Concrete (RCC) is the key word in Dam building industry of today’s brave new world. India is also going in for its first ever RCC dams for Ghatghar Hydro Electric Project, of Irrigation Department of Government of Maharashtra. Ghatghar Pumped Storage Scheme is the first ever largest Scheme (250 MW) comprising two units of 125 MW each. Ghatghar Hydro Electric Project is unique of it’s kind in India. The use of reversible turbine pumps for two generating units for first time and use of RCC technology for three dams is also for first time.
All the three dams have to be built one after another in the increasing order of height and volume of RCC placement. The lessons learned from each earlier dam, regarding construction methodology, adequacy of plant and equipments, results of strength obtained will be useful for later one. This step by step approach will facilitate in building the confidence level and heading toward perfection. Successful completion of three RCC Dams in Ghatghar Project will definitely lead to adoption of RCC technology in upcoming new dams.
