 In this study, the use of recycled concrete aggregate as a replacement for natural aggregate was evaluated. The recycled aggregate was mixed with various mineral additives and nanosilica to improve its physical and mechanical properties. The results showed that the recycled aggregate concrete mixes had higher compressive strength than the control mix made from natural aggregate. Additionally, the addition of nanosilica and mineral additives resulted in denser and more compact microstructures. This article was authored by Amal Fawzi, Ahmed El-Shami, and Salim Amad.
