TL;DR: In this paper, the authors present theoretical and applied state-of-the-art information in the field of alkali-aggregate reactivity (AAR) in concrete.

TL;DR: In this paper, a mixture proportioning method for concrete made with coarse recycled concrete aggregates (RCA) is proposed, which is predicated on the fact that RCA is a two-phase material comprising mortar and natural aggregate; therefore, when proportioning a concrete mixture involving RCA, one must account for the quantity and quality of each phase and adjust both the coarse aggregate and fresh paste content of the mix accordingly to achieve the same total mortar volume as a companion mix with the same specified properties but made entirely with coarse natural aggregates of similar properties to the coarse natural aggregate

TL;DR: In this article, a comprehensive investigation about the durability of structural-grade concrete made with recycled concrete aggregate (RCA) is presented, where the RCA-concrete mixes were proportioned using a new concrete mix design method, termed the equivalent mortar volume (EMV) method.

TL;DR: In this article, the effects of a new method of mixture proportioning on the creep and shrinkage characteristics of concrete made with recycled concrete aggregate (RCA) are investigated. And the results show that the amounts of shrinkage in concretes made with coarse RCA, and proportioned by the new method, are comparable to, or even lower than, those in similar concrete made entirely with natural aggregates.
