Masonry at low temperatures

Masonry manufactured in winter, differs from the usual masonry. The main difference is due to the fact that the cement mortar used for masonry, at temperatures below 5 ° C, is more slowly hardened, and at temperatures below 0 ° C, the solidification of the solution practically stops. The reason for this is water in the solution. Water simply freezes and turns into ice, subsequently which is violated by its interaction with astringent. You also need special equipment. First of all, a car accident. Renting an auto crane is inexpensive, so there will be no problems with an autocrane.

The result of freezing of water may be poor strength of the solution, as well as the impossibility of sufficient sealing horizontal seams. As a result of which uneven sediment and subsequent destruction of the masonry can occur. Currently, there are three masonry methods used at low temperatures. The method of freezing is that the final hardening of the solution occurs in spring time. A similar method can be used in the construction of buildings with a height of not more than 15 meters. The next method is to use special chemical additives. Using additives, the temperature of freezing of water in the solution decreases, which allows the solution to gain strength, even at low temperatures. The third method is carried out by heating. The technology of warming up, consists in warming up the finished masonry, which allows you to perform artificial thawing masonry of the whole floor. After which it is possible to continue the construction of the following floors that have already gained strength, lower.
