Raw bricks: production technology

The raw brick is produced in the same way as ordinary ordinary kind, except for the use of roasting. It is used in the construction of low-rise structures or fences, because it has little strength.

• The main difference from ceramic is the stage of roasting, in connection with this raw material has a small moisture resistance. For this reason, the use of such a brick is in demand only in continental zones with a sharp precipitation.
• Bricks made of crude are fire-resistant, they have rather good sound insulation and thermal insulation. With such important advantages for the building element, the cost of the material is quite low. Applying raw brick in climatic zones with an unusually warm air temperature, people solve many problems simultaneously.
• The production of raw building materials can vary significantly, as various additives are introduced, it all depends on the climate of the area. This is necessary to improve the strengths of the brick that are required in the climatic zone. To increase the strength of the material, a small amount of straw is added, plasticity requires liquid glass, and moisture resistance increases cement.
• Most often, raw materials for construction are used in the regions of Europe, Africa, and Asia. These zones have a hotter climate in the summer, and a warm winter without precipitation of a large amount of precipitation. On the territory of the Russian Federation for the construction of houses is not used because of the sharply continental climate.

Preparation of clay

The quality of natural clay material directly depends on the terrain on which its extraction is planned. In this case, clay layers are located in the lower levels of the soil. Most often, mining is carried out in specially designated areas, that is, quarries. To determine if there is clay on the site or not, it is necessary to pour water on the ground. If an oily surface is formed, clay is in most cases present.

Before starting to produce raw bricks, it is necessary to analyze the clay. The quality of the material is determined by the density of the fat content of the natural material. The analysis is carried out in this way: a sample of clay is taken and mixed with water until a clump is formed on the block. After this, it is necessary to make clay balls, about 10 pieces. They are then subjected to a drying process.

The next step is to check the material for strength, take dried balls from clay, and then rush from a height of 1 meter to a hard surface. In case the balls remain intact, the material is ideal for making raw brick for construction.

Preparation of mass

Ordinary natural material (clay) is mixed with water. This process can be carried out the same way in both a special container and a shallow pit. In order for raw bricks from clay to be of high quality, at the time of making the solution, all waste should be screened out. To improve the characteristics of the building material at the time of production, various elements are added.

• To reduce shrinkage at the time of drying, sand or crushed gravel of fine fraction is added. But they bring a significant minus to the product, it becomes more fragile.
• In order to accelerate the drying process, a small amount of cement is added to the finished mass. It not only accelerates the hardening process, it also gives moisture resistance to the product.
• Improved raw brick with straw Has a light weight and good thermal insulation properties. In some situations, wood chips or manure are used instead of straw.

Forms for the manufacture of products

To produce a product of a building type, forms are needed. They can be different, for example, made with their own hands.

For the production of molds, a wood material is required, by means of which a framework of the required size is assembled. This option is suitable for the production of products in small quantities. Formed raw brick, photo Which is located below, is suitable for an illustrative example.

Attention

Such a formation is completely unsuitable for the industrial production of raw products. In this case, special equipment is used, which makes it possible to produce products in large quantities. This equipment exposes the material to pressing.

The formation of a mechanical type allows the material to be pressed to 20 tons. Simultaneously, more than 15 products of building material are manufactured. Such a number of a raw element can not be obtained at home.

Stage of drying products

The drying process is one of the most important and responsible, therefore it is necessary to treat it very carefully. In order to avoid moisture on the products during the drying process, it is necessary to build an open canopy. In this case, the wind can freely blow raw products from all sides.

This process lasts approximately 14 days or more, from the moment of laying out the products under the awning. The number of days depends on the weather conditions. It is important to remember that the bricks, after complete drying, are reduced by 12 percent. For flooring, it is best to use boards of medium thickness so that they do not sag under the weight of the raw elements.

In many cases, raw brick, whose production technology is a complex process, has many advantages. After the drying process, the building brick can be used immediately in the construction of buildings.

Attention

The main importance of the technology of production of a raw element for construction is considered any small thing. At the moment of making a clay solution, the exact composition of the future building material is important. This will determine the quality and characteristics of the products. The drying process is best carried out in the spring season. This is to ensure that the planned erection of the house was ready for use at the end of the summer.
