A new method to determine the density and water absorption of

For natural aggregates this is usually not a problem because they are not particularly porous and so have low water absorption potential. But recycled aggregates absorb far more water and it is imperative to compensate for this during concrete production.

Cement paste content and water absorption of recycled

Abstract. In this paper, we first show that the amount of residual cement paste in recycled concrete aggregates (RCA) depends on the initial paste content, on the mechanical properties of the initial cement paste and on the mechanical quality of the trans

Effect of Recycled Coarse Aggregate on Concrete Properties

Moreover, in terms of RCA use will influence high water absorption of recycled aggregate, of concrete (Fumoto and Yamada, 2006). This is due to the migration of water absorbed by the aggregate to the paste around particles of aggregates, then, the water a
