Accelerated curing at an early-age of cement-based materials using microwave energy: A proposed heat transfer model

Microwave energy is applied to cure cement paste (CP) at an early stage. This article presents a heat transfer analysis to relate the temperature rise of the 0.45-w/c CP when subjecting to microwave energy at an operating frequency of 2.45 GHz with a multi-mode cavity. The calculated temperature rise in our experiment without loss of moisture and steady heat transfer conduction, consistently agreed with the proposed mathematical model.
