How long does it take to repair the wall with cement?

It usually takes about 3 days on a sunny day, but if the weather is wet, it will take at least a week to dry completely. Science popularization of related knowledge: 1. Cement solidification is divided into two stages, one is initial setting, which usually takes more than 45 minutes to reach this stage. At this time, the concrete will just start to set and lose its plasticity. It looks like the cement is dry on the outside, but it is still wet inside. The second stage is final setting, which takes no less than 10 hour to complete. At this time, the cement has been completely dried from the inside out, forming a hard cement state, which has a strong supporting role. 2. Because cement takes a long time to set, in order to save time, most people will choose to use concrete to repair the wall. Because the composition of concrete not only contains cement, but also contains many mixed materials, such as accelerators or accelerators that affect the setting time. These materials will accelerate the setting of cement. In the past, it took 65,438+00 hours for cement to completely set. After adding accelerator, it may take only 2 hours to completely dry. In order to save time and labor costs, concrete is more suitable.
