Microwave curing of concrete bridge repairs

The paper introduces the FP7 MCure project on the "Development and demonstration of an energy efficient system for accelerated curing during repair and refurbishment of concrete structures". It provides test results on microwave curing of six commercial repair materials. The results provide the basic relationships between microwave energy input and curing characteristics of the repair materials by presenting data on the following aspects:

• Surface temperature profiles and hot spots.

• Interrelationships between temperature profiles, power input, volume and microwave curing time for different repair materials.

• Response of different repair materials to microwave power.

• Recommendations on optimum curing temperatures and curing time.
