MICROWAVE CURING OF PORTLAND CEMENT CONCRETE: EXPERIMENTAL RESULTS AND FEASIBILITY FOR PRACTICAL APPLICATIONS

The acceleration of strength development in concrete is beneficial to many operations in construction, such as precasting and pavement repair. In this paper, the effects of microwave on the early (at 4.5h) and later age (7 day) strength of both mortar and concrete specimens are reported. With microwave curing, type III Portland cement concrete can develop early strength and later age strength that compare very favourably with commercially available rapid hardening concrete as well as concrete containing accelerating admixtures. With the experimental results demonstrating the potential of rapid curing with microwave energy, important issues relating to the development of the microwave curing technique for practical construction applications are discussed.
