on the strength development rate of concrete and found that microwave
curing can lead to further improvements while eliminating the concerns
about concrete deterioration related to steam-cured concrete [20]. In 2008,
Rattanadecho et al . used a continuous microwave drier to accelerate the
curing of mortar specimens [21]. The continuous microwave system used
had fourteen 800-W magnetrons to achieve a maximum power of 11.2 KW
