A: After the concrete is poured, the slurry has no strength yet, and the hardening of the concrete depends on the hardening of the cement. For example, the initial setting time of ordinary Portland cement is 45 minutes, and the final setting time is 10 hours, that is, the concrete is poured and smoothed and placed there without disturbing it, and it can slowly harden after 10 hours. If you want to increase the setting rate of concrete, you need to use the steam generator for steam curing. You can usually notice that after the concrete is poured, it needs to be poured with water. This is because cement is a hydraulic cementitious material, and the hardening of cement is related to temperature and humidity. The process of creating suitable temperature and humidity conditions for concrete to facilitate its hydration and hardening is called curing. The basic conditions for conservation are temperature and humidity. Under proper temperature and proper conditions, the hydration of cement can proceed smoothly and promote the development of concrete strength. The temperature environment of concrete has a great influence on the hydration of cement. The higher the temperature, the faster the hydration rate, and the faster the strength of concrete develops. The place where the concrete is watered is wet, which is good for its hardening.
