Figure. 2 (IMAGE) Kanazawa University Caption Curing process. After the water absorption treatment, the specimen was subjected to steam curing (heating rate: 15 ºC/h, maximum temperature: 90 ºC, maximum temperature holding time: 48 h, cooling rate: 15 ºC/h). Next, heat curing (heating rate: 60 ºC/h, maximum temperature: 180 ºC, maximum temperature holding time: 48 h, cooling rate: 60 ºC/h, 1 atm) was applied.
