Pore characterization of manufactured aggregates: recycled ...

2011-6-15  Characterization of aggregates prior to their use in concrete production is an important activity from a durability standpoint. In general, aggregates are characterized by the void space or the pore volume, shape and size and mineralogical properties.

Microstructure of Recycled Aggregate Concrete SpringerLink

2018-6-17  The microstructural characterization of concrete prepared with RCA is described in this chapter. The interfacial transition zone (ITZ) between the aggregate and the cement mortar matrix is the most important interface in concrete. Particularly, this is very important in RAC, as the recycled aggregate concrete has more interfaces than normal ...

2019-7-3  The study tries to demonstrate the effect of metakaolin to enhance the qualities of concrete prepared with natural coarse aggregates (NCAs) and recycled coarse aggregates (RCAs). Recycled aggregate concrete (RAC) mixes are made by substituting NCA with 100% RCA and ordinary Portland cement with 10, 15 and 20% metakaolin.
