Abstract
Striving for more ambitious development using Recycled Concrete Aggregates (RCA) in new concrete development, this paper summarises the results of an experimental study on air-entrained, normal strength structural concrete. Effect of new paste volume was investigated with and without the use of high-range water reducing admixture. Aggregates consisted of commercial grade, controlled quality RCA of different gradations. Mechanical and durability aspects of concrete incorporating coarse RCA up to 30% replacement and granular RCA up to 20% replacement were found to be comparable to those of virgin aggregates, and controllable through modification of paste content and composition, in order to achieve the desired mechanical and durability properties of sustainable concrete.
