To investigate the deterioration of granite under microwave irradiation and heat transfer, granite specimens were heated up to 400-1000 °C and then kept for 15 min. Uniaxial compressive strength testing results demonstrate a similar variation in two groups in 400-900 °C, which is initial strengthening (less than 500 °C), subsequent weakening (500-600 °C) and final stabilizing (600-900 °C). Furthermore, the specimen irradiated by microwaves Citation: Hu, Q., Shou, Z., Zeng, J., He, L., Tang, H., Li, B.,Chen, S., Lu., X., Comparative study on the deterioration of granite under microwave irradiation and resistance-heating
