During the transition of one material from macro-to nano-range size, considerable changes
occur in the electron conductivity, optical absorption, mechanical properties, chemical …

The main problem in using recycled concrete aggregate (RCA) as a construction material is
due to the weak adhered mortar which usually has higher porosity and water absorption. It …

Recycled concrete aggregate (RCA) produced from concrete waste has recently been a
good alternative to natural aggregate because of the increased focus on sustainable …
