You are a professor in the field of building fires in civil engineering please help me revise the following text to make it suitable for SCI journalsAs previously discussed the migration of moisture i
As discussed previously, the migration of moisture in concrete over a short period can be negligible. However, water and vapor that overflowed on the outer surface of the ceiling quickly migrated inside the concrete through cracks. During their migration from high-temperature to low-temperature areas, they were cooled. In the initial stage of the fire test, the temperature of the concrete was low, the internal cracks were small, and the vapor pressure inside the concrete was not high, resulting in relatively slow migration of water and water vapor to the low-temperature area. A small amount of water vapor was rapidly cooled by the concrete and condensed into liquid water. Consequently, only a small amount of liquid water overflowed from the concrete cracks, and the temperature did not increase significantly. Fig. 5 and Fig. 12 depict the water overflow on the ceiling surface and the infrared image of the ceiling, respectively.
As the fire test progressed, the concrete temperature increased gradually. Under the influence of high temperatures, the moisture in the concrete vaporized rapidly, and the pressure inside the concrete increased rapidly. High-pressure vapor inside the concrete was released through cracks. At this time, the internal cracks in the concrete were relatively large, and the vapor pressure could propel the water and vapor in the concrete to quickly migrate to the low-temperature area through the cracks. Water and water vapor lost less heat during their rapid migration to the low-temperature area. Therefore, a significant amount of high-temperature water and vapor overflowed from the concrete cracks, as shown in Fig. 15. At 95 min, boiling water and vapor overflowed from the concrete cracks, but the temperature monitored by infrared was 85.7°C. This was due to the high-temperature water vapor being cooled by low-temperature water and concrete during its migration to the low-temperature area
