Roller Compacted Concrete (RCC) recent developments and innovations

In the recent 30 years, after completion of various all RCC dams across the world, the experience and knowledge gained through the completion of over 350 RCC dams are almost a reality with our neighbouring country Pakistan soon to embark on the construction of a 272 m high RCC dam on the Indus river, the paper deals with two most important developments in history of RCC. One being the solution to the problem of achieving bond by placing the RCC lifts within the initial set time of the RCC, the other achieving a durable, impermeable and aesthetic facing to the RCC by altering in-situ the proportions of the RCC with the addition of grout to the uncompacted as spread RCC so that it will behave as conventional concrete when internally vibrated.
