Abstract

The work refers to an innovative recycling solution of wastes from demolition and rehabilitation of buildings to produce more cost-effective lightweight aggregates. The adopted method is based on the use of microwave energy as a nonconventional source, replacing conventional energy sources and expanding the powder mixture of raw material with silicon carbide as a foaming agent. The final product has a porous structure and a high compressive strength (over 6 MPa), being suitable for use as a lightweight aggregate for concrete manufacture.
