Accumulated construction and demolition waste (CDW) can occupy much land and cause
environmental pollution. To dispose of CDW and slow down the depletion of natural …

Compared with natural aggregate (NA), recycled coarse aggregate (RCA) is of lower
strength and higher porosity due to the attached mortar, which limits the application of RCA …

When it comes to sustainable construction, recycling is one of the significant aspects to
consider. Reusing waste from construction and demolition activities and utilizing recycled …

Purpose This study aimed to review various existing methods for improving the quality of
recycled concrete aggregates (RCAs) as a possible substitution for natural aggregates …

Utilization of recycled brick aggregate (RBA) in concrete production is limited due to its high
porosity, which negatively affects the strength and durability of concrete. This study aims to …

Recycled aggregate concrete (RAC) typically suffers from inferior properties due to old
mortar on the surface of recycled aggregate (RA), and the practical application of two …

The absorption of water by recycled coarse aggregates (RCAs) is significantly greater than
that by natural coarse aggregates (NCAs), which affects the mechanical properties of …

Surface coating is a simple and effective method to reinforce recycled aggregate (RA), and
its efficacy is closely related to the basic property of surface-coated material (SM), such as …

Preparing concrete with coal gangue as the aggregate has significant environmental and
economic advantages. Nevertheless, the fundamental characteristics of the manufactured …

This study compares the effects of three techniques for reinforcing recycled concrete
aggregate (RCA): chemical reinforcement, biological modification, and chemical-biological …
