How long can cement solidify at minus 4℃? How many degrees below zero can cement not be constructed?

Cement is one of the essential materials for home improvement construction, and it also has certain requirements for construction conditions. Generally speaking, the temperature is too low for cement to set normally. Today, I will talk to you in detail about how long cement can solidify at MINUS 4℃, and cement cannot be constructed at MINUS several degrees.

How long can cement set at MINUS 4 degrees?

The speed of cement solidification must be very slow in winter, because the temperature is particularly low in winter. In winter, if we want to use cement to make concrete, then we can add some antifreeze to it. If the amount of cement in your house is not particularly large, then we can blow it with a hair dryer, which can speed up the solidification of cement. If the temperature is below zero in winter, it takes a long time for cement to set, usually it takes more than eight hours to start setting slowly.

Cement can't be constructed when the temperature is below zero.

In general, when the temperature is lower than 10℃, construction cannot be carried out, because if ordinary cement is constructed at low temperature, its hydration speed will be greatly affected, which will accelerate the evaporation speed of water in it. If the construction is carried out at this temperature, it will be very troublesome to maintain after the construction, and problems such as cracking will easily occur in the later stage.

Additional: Precautions for Cement Construction

1, this type of building materials must be preserved after cement construction, and cannot be placed in the sun. Because after sun exposure, all the water in cement will evaporate, and its strength will drop rapidly. In severe cases, the strength will directly fail. In addition, before cement construction, the construction surface should be cleaned, soaked in water, covered with articles after construction, and then watered as required.

2, cement in the construction, also should pay attention to save, can't be eroded by water let it go, otherwise once be affected with damp, it will harden, which will affect its strength. At the same time, cement with a shelf life of more than three months must be tested before use to see if its strength meets the construction requirements. Do not meet the use requirements, can not be used.

3, cement construction in the construction, also need to pay attention to the weather. Choose suitable weather for construction, such as hot and humid weather, which is not suitable for cement construction, because water evaporates very quickly, which seriously affects its strength, and the calcium hydroxide contained in it will also decompose.

The full text introduces in detail how long cement can solidify at MINUS 4℃ and how long cement can not be constructed at MINUS several degrees. It is suggested that if the ambient temperature of cement construction is low, even below zero, it is best not to construct, and the construction can wait until the temperature rises.
