The temperature during the pouring of concrete for arranging

Creating a solid, reliable structure is the result of a carefully and competently done work, the basis for the production of which will certainly be a high-quality and durable foundation. Bookmark this element of the future building is of great importance. In the construction process should be based on a large number of features. This process requires builders to take into account a huge number of conditions.

The strength of the mixture for the foundation is determined not only by the quality of the concrete itself, but also by the technology of its construction, as well as by the weather conditions in which it is laid. Exactly at what temperature concrete is poured can affect the strength and durability of the future structure. Therefore, it is very important to know at what minimum temperature concrete can be poured.

The quality of the solution in different temperature conditions

Modern construction mixtures contain in their composition some additives that make it possible to carry out construction work both in winter and in summer. But concrete still has chemical properties, which cause some restrictions for working with this material.

The process of creating a monolith is divided into two main stages:

1. Concrete setting. The time to complete this stage is no more than a day;
2. Concrete hardening.

The time of completion of this stage is determined by the following parameters:

• Brand solution;
• The presence of chemical additives in the composition;
• Temperature regime;
• Humidity level

Let's find out at what temperature you can pour a concrete screed. The optimum temperature is from 3 to 25 degrees. Such conditions allow the foundation to go through both stages of hardening in the shortest possible time with the best quality indicators.

Note! The speed of the process depends on the temperature. It is warmer outside, the faster the mass gains strength.

Ambient temperature and other weather conditions can have a serious impact on the rate of hardening of the foundation and also on its strength. This dependence is directly related to the fact that water in a solution can change its state from liquid to solid.

Winter construction

To understand at what temperature it is impossible to pour concrete, it is important to remember that at a temperature of -3⁰With water in the solution begins to crystallize. In this process, the structure of the product can be irreversibly disrupted, and microcracks form on the surface, which over time will only grow.

But despite this, it should be noted that the temperature below zero can cause the hydration process to stop. This means that the hardening process slows down and just stops.

Note! If the temperature rises after the concrete freezes and the solution is defrosted, the broken connections will not be restored anyway, which means the product quality will be lower.

But construction is a process that is limited in time and you have to work even in cold weather. Therefore, for developers, the actual question is about at which low temperature concrete can be poured.

In order to fill the foundation with your own hands in sub-zero temperatures, you can use the following methods:

1. Heat the solution;
2. Ensure the warming up of the poured structure;
3. Work with a product of high marks;
4. Introduce specialized antifreeze plasticizers and other additives into the building mixture.

Note! Using these methods, you will get a solid and reliable construction, for drilling or cutting of which you should apply such methods as cutting reinforced concrete with diamond circles and diamond drilling of holes in concrete.

Is it possible to practice the foundation in the cold

More recently, frost could cause a delay in construction, the use of modern technology made it possible to carry out construction work even in winter.

Working in a frost, it is necessary to follow the requirements that are specified in the instruction for winter pouring:

1. Digging trench or trench;
2. Installation of formwork;
3. Installation of reinforced frame;
4. Provide heating structure, which will be poured concrete;

Note! It is especially important to carry out the heating of the formwork and the cast mass during the first 48 hours, just at the time when the setting takes place.

1. Preparation of waterproofing, which covers the filled solution;
2. After the first two days, heating can be reduced.
3. After the mass has hardened, the formwork should be removed and the structure left to gain strength.

Recommendations when working in sub-zero temperatures

Filling of concrete at low temperatures for the construction of the base of the structure is the most crucial and important process that requires the developer knowledge of some of its features:

• Before pouring in the winter, you should be sure that it is possible to create conditions that will help the foundation to have a standard level of strength without microcracks and damage. It should also be understood that the price of construction work in the winter time will be slightly higher;

Note! Kneading of the solution entails some chemical reactions, accompanied by the release of heat, so that the mixture during the pouring can warm up independently.

• In order for more heat to be emitted, a fine fraction should be used, since he is much faster to interact with water;
• The thicker the concrete layer, the more heat will be released, and, accordingly, the slower the monolith cools down;
• If necessary, increase the temperature of the solution should be heated only water or additives. Cement can not be heated in any case, because it will lead to loss of binding properties of this component of the building mass.

Finally

Now, when it became clear at what temperature it is possible to pour concrete, and from the above, it is clear that concrete can be laid at any time of the year, the main thing is to follow the technology and withstand the time of final hardening of the mortar. But despite the fact that there is a possibility of pouring the foundation in the winter, you should still do such work in the summer.
