Mats for concrete heating: areas of application.

The ideal conditions for concrete hardening are considered to be + 18-20? and relative humidity up to 90%. But at the onset of cold weather, water freezing in the mixture slows down hydration, as a result of which the concrete solution does not freeze. Now the most effective means for successful drying of the mortar in the winter is electric mats for heating concrete.

It is a safe, relatively inexpensive and convenient device.

What are thermomats

This device is designed for heating concrete and reinforced concrete blocks and structures. TEMS (thermoelectric mat construction) significantly accelerates the hydration of the mixture, preventing the deterioration of its technical properties.

Today, concrete heating mats help workers complete the task on time and turn in a quality object in all weather conditions.

Areas of use

Увеличение темпов строительства не должно воздействовать отрицательно на качество продукции (читайте также статью «Провод для прогрева бетона: подробное описание»).

Therefore, devices actively help in the following situations:

1. At construction of horizontal overlappings, floors, couplers.
2. When building roads and squares.
3. Accelerated solidification of formwork and curbs.
4. It creates high-quality coverage for airfields.
5. For heating various pipelines and highways.
6. Heating of barrels and tanks of large volume.
7. Warming up brick and masonry.
8. Mats for concrete heating are also used for frozen ground, before carrying out earthworks.

What is the device

1. The heating layer of infrared radiation, based on the "pulse" - a polymer material.
2. Air-filled insulating layer.
3. Heat reflecting layer of special material.
4. Water repellent polyvinyl chloride layer.
5. Bimetallic thermostats.

The flat and flexible heating element is built into the PVC cladding. On the one hand, the structure is closed with a sufficiently thick (1–2 cm) heat-reflecting layer. The heating wire is connected to the heating layer with switching connectors at the end.

Thermostats are needed to adjust the temperature. Thus, the instruction provides for automatic shutdown of the device when the temperature reaches +70 ?. When lowering it to +60? the thermostat turns on the mat again.

Note! Thermomats successfully replace large and expensive equipment. Now you will not need a mini-station and a transformer, enough light mobile devices.

Specifications

Types of devices and cost

In addition to devices for heating concrete, manufacturers offer options for devices used for the following:

1. Heating of frozen soil before earthworks. The device will help you to prepare the soil with your own hands in just 24/36 hours.
2. For heating columns and joints between concrete slabs.
3. To warm the large capacity, as well as the trunk of the pipes.
4. Possible mixed-type heating. Initially, the ground is prepared, then the process of solidification of poured concrete is accelerated.

As for the cost of equipment, the price may vary, depending on the place of purchase. So, buying directly from the manufacturer will cost 10,000 rubles, while prices in the store may be slightly higher.

The device can be ordered complete with the necessary additions. In this case, the mats will cost you from 2 300 rubles per m2. Often it is possible to rent a device, it is a convenient and economical option.

Installation and operation

Thermomats are extremely easy to use, therefore, following the rules, almost anyone can use them.

1. The equipment is unpacked and spread on the right places.

Note! Before installation and during it mats should be disconnected from the mains. You can use only working and serviceable sockets.

1. The mat is spread on the work surface with an exclusive heating surface down.
2. Before laying the device, the concrete surface is covered with plastic wrap. This is necessary to prevent contamination and sticking of the mat to the solution.
3. If at the same time reinforced concrete is cut with diamond circles, all tools and accessories are removed before the installation of thermoplates.
4. Walking on a laid surface is also not allowed.
5. If there is a need to connect the mats to each other, as well as to facilitate fastening vertically, eyelets will be useful.

How it works

A device connected to a current source is considered ready for operation and starts heating.

1. Since the mats are equipped with an effective heat insulator, laid correctly (heater to the working surface), they do not allow heat losses.
2. When the desired temperature is reached at +70 ?, the device automatically turns off. This is done by thermal sensors that open the circuit.
3. As soon as the device cools down to + 55 / + 60 ?, the circuit closes again, bringing the thermomat to the desired temperature.
4. Several elements connected to each other have independent thermal sensors, which adds convenience in operation.
5. Mats have a grounded plate that distributes heat. Even with a loose fit, the quality of warming does not suffer.

If diamond drilling of holes in concrete is planned, the heating device should be temporarily turned off and removed from the working surface.

Conclusion

В помощь строителям предлагается масса полезных устройств. Теперь можно без опаски проводить работы и в зимнее время. Низкие температуры и погодные условия не помешают достичь качественного результата (см.также статью «Выбираем, какая марка бетона нужна на фундамент»).
