ABSTRACT
Immersion Vibrated Roller Compacted Concrete (IV-RCC) is a mass concrete for dam construction. A special mix design has been recently developed for the construction of new concrete dams with the aim of providing best quality to RCC dams, similar or better than the traditional conventional vibrated concrete (CVC). The key advantage of this new type of concrete is that it can be placed and consolidated either like RCC or like traditional CVC. The decision on which methodology should be used for its application can be decided on site, at the point of placement. In this context, we see an opportunity for making good use of this material in the raising, upgrading and renewal works of existing concrete dams in Europe and elsewhere. The paper describes specific characteristics of the materials and mixes required for IV-RCC, as well as some of the specific construction aspects and advantages. The in-situ performance based on existing completed projects is also presented in the paper. Particular attention is paid to specific high-quality mixes as those required, for example, for concrete arch dams.
