The weather turned cold and Luoyang had already snowed. The workers are still under construction.

In the construction of refractory castables, environmental and seasonal changes such as temperature and humidity should be considered.

In winter, when the refractory castable is applied, the ambient temperature must be controlled at -5~+5 °C. If the temperature is lower than -5 °C, it is necessary to do the cold-proof measures before construction.

In addition, the dry material should be stored in the heating room first, and stirred with hot water. The temperature of the castable after stirring should be controlled above 10 °C. Note that at this time, do not add a chemical coagulant and antifreeze.

Rongsheng friendship reminder: the construction requirements of castables are different in different seasons. Therefore, we must pay attention to the use environment of castables when we build castables.
