At what temperature can you put a brick without damage to the construction?

Usually, construction work is carried out in the warm season. Winter is not considered the best time for laying bricks and other works. But in any rule there are exceptions. For example, when the building does not survive the conservation for the winter and can significantly collapse during this period. Before starting the construction process, you need to find out at what temperature you can put a brick.

Problems of brick laying in winter

Many people ask the question: "Why not put a brick in the frost?" We recall the composition of the solution and physics. So, for brick laying a mixture consisting of water, sand and cement is used. It is water that plays a key role here. It is something that slows down the whole process. At minus temperature, the water takes a solid aggregate state and turns into ice. Therefore, the process of hydration does not occur between the masonry and the mortar. Even if in the masonry the water does not have time to freeze, some of the bricks will be covered with ice. When the air temperature rises and the ice begins to melt, the strength of the masonry will fall by a factor of two. The water that was inside the entire structure, too, will melt, and the entire structure will collapse quickly. And yet at what temperature can you put a brick? In order for the ordinary cement mortar to seize and dry, the street should be at least -5 ° C. Otherwise, the spring construction will collapse.

How to prepare mortar for winter laying?

But, despite all these subtleties, a method has been found to increase the indicator of how high a brick can be. To do this, use a special solution, which includes antifreeze additives. With their help, the temperature limit was reduced to -50 ° C. This method of building buildings is very popular in places where the air temperature is below zero for most of the year.

After the masonry is laid, it remains to follow the freezing of the solution. To do this, in the masonry make a kind of holes with plugs, inside of which a thermometer measures the temperature.

If it is impossible to observe the thermal regime when hardening, special equipment is connected for heating and drying the masonry. If the frost is very severe, it may be necessary to install additional tellyaks. They are mounted above the masonry. Now for builders, the question of what temperature can be used to lay a brick is not so acute.

It must be taken into account that additives that do not freeze solution are harmful to humans. Therefore, you only need to put a brick in a special protective suit.

Several ways to lay bricks in the cold season

For quality work in minus weather, the following technologies are used.

Electroheating. This is the most time-consuming and energy-intensive method. It is used for the construction of small sections of walls. In the process of laying, electrodes are placed in the solution through which an electric current is passed . With its help, the seams dry out, and the formation of ice is ruled out.

Arrangement of a greenhouse. This method is highly efficient and economical, but it is quite laborious. On the place where the wall will be driven out, a frame is mounted on which polyethylene curtains will be stretched. Inside the tent formed a source of heat and begin construction. Such a hothouse must be heated for a long time, until the masonry is dry.

Frost. Here, a frost-resistant solution is used, which, after the onset of warm weather, can again grasp. In the process of work, it is important to ensure that there are no intentions on the consumable. If any, dispose of them with an injection torch.

The final stage

After the answer is found to the question of at what temperature it is possible to lay a brick, and the foundation for future walls has already been laid, we pass to the final works. After the height of the wall becomes equal to the height of the first floor, prefabricated ceilings are installed.

At the onset of a thaw, it is necessary to follow the state of the masonry. Additional strength is provided by internal transverse walls, the distance between them should not exceed 20 meters. The more often the transverse walls are located, the stronger the structure.

Brick laying is a complex process, and frost only complicates this procedure. Strict adherence to and implementation of all stages of work will make it possible to build a strong and reliable building even in winter.

So you found out at what temperature you can lay a brickwork, and got acquainted with the ways of laying a brick in the winter.
