Abstract
Recycling of concrete into high quality products requires the separation of the cement matrix, sand and aggregate particles. Microwave heating stands as a strong candidate for selective liberation of these constituents, either directly or as a pre-treatment to a comminution step, as it takes advantage of the many contrasts in properties of the phases: thermal, mechanical, electrical and dielectric. Rapid microwave heating generates stresses within the concrete, which may lead to crack formation at phase boundaries, yielding liberated constituents. This work is a contribution to demonstrating the potential of microwave treatment for the selective liberation of concrete components.
