Concrete heating make winter construction feasible

The Construction of industrial facilities of metal in our day does not stop for a minute, even in the bitter Northern cold. This involved highly skilled builders to implement its activities in advanced technology winter construction, in particular, heating of concrete.

So, in normal mode, in accordance with SNIP, you can make work on the construction of the bases at temperatures below minus five degrees. If the temperature drops below this level, then the builders use other technologies to enable the concrete to harden without consequences in such frosty conditions.

One such technology, – concrete heating due to heat emitted directly from used in the construction of concrete mortar. To do this in production, use the hot steam or water, pre-heated to ninety degrees Celsius.

The Second kind of winter construction technology – the effect of a thermos is cozy casing around the concreted object. Effective for quick setting and is considered the technology of infrared or electrode heating solution. For this purpose, the tubular emitters, which is conducted through the electric current. They can be ceramic or quartz. For these methods need a transformer for heating concrete. The following method of providing temperature to obtain a strong concrete – the use of heating or thermally activated formwork, which includes the wire for heating of concrete.

In Russia the most widespread technology for the use of chemical additives, which are included in the concrete mix to reduce freezing point so that the concrete sets much earlier than it begins to freeze. Plants for the production of concrete believe this technology is the best for them, because construction companies without worrying about additional hardware, just buy a frost-resistant solution they need stamps and concrete warm they do not care. Good or bad, it's hard to say.

So far we only know that in other Nordic countries such as Finland, Sweden, construction companies, equipped with special equipment that gives them the opportunity to choose the way of working with concrete in winter conditions to provide the expected level of strength year round and prevent heaving effect in the winter.

The Advantage of winter construction lies in the fact that in the winter cold season much easier to organize access roads to the object. Snow drifts can be easily removed by snow plows, the snow is compacted and technology without the obstacles associated with mud and eroded by rain and rain is expensive, drives up the necessary materials, equipment and people.

Another important advantage that makes appropriate winter construction using concrete heating, the decrease of the total number of construction projects, and thus in the released labor force, reduced the tension, the excitement and the rush. Objects are built consistently and more prudent. The company is building its warehouse and production premises in the winter, only to win.
