Raw brick is produced in the same way as the ordinary ordinary type, except for the use of firing. It is used in the construction of low-rise structures or fences, because it has low strength.
- The main difference from the ceramic is the firing stage, in this regard, the raw material has little moisture resistance. For this reason, the use of such bricks is in demand only in continental zones with sharp precipitation.
- Raw bricks are fire resistant, have pretty good sound insulation and thermal insulation. With these important advantages for the building element, the cost of the material is quite low. Using raw brick in climatic zones with unusually warm air temperatures, people solve many problems at the same time.
- The production of raw building material can vary significantly, as various additives are introduced, it all depends on the local climate. This is necessary to improve the advantages of bricks that are required in the climate zone. To increase the strength of the material, a small amount of straw is added, liquid glass is required for ductility, and moisture resistance increases cement.
- Most often, raw material for construction is used in the regions of Europe, Africa, as well as Asia. These zones have a hotter climate in the summer, and warm winters without heavy rainfall. In the Russian Federation for the construction of houses is not used because of the sharply continental climate.
Clay Production
The quality of the natural clay material directly depends on the area on which it is planned to be extracted. In this case, clay layers are located in the lower soil levels. Most often, mining is carried out in specially designated areas, i.e. 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 forms, then in most cases clay is present.
Before you start producing raw brick, you should 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 as follows: a clay sample is taken and mixed with water until a sticky layer forms on the block. After that, it is necessary to make clay balls, about 10 pieces. Then they undergo a drying process.
The next step is to check the material for strength, take the dried clay balls, after which they are thrown from a height of 1 meter onto a hard surface. In case the balls remain intact, the material is ideally suited to make raw brick for construction.
Cooking mass
Common natural material (clay) is mixed with water. This process can be carried out equally in a special container, and in a shallow pit. In order for the raw clay brick from the clay to be of high quality, all garbage should be screened out at the time of making the solution. To improve the performance of the building material, various elements are added at the time of production.
- To reduce shrinkage at the time of drying, sand or gravel of small fraction is added. But they bring a significant minus to the product, it becomes more fragile.
- In order to speed up the drying process, a small amount of cement is added to the finished mass. It not only accelerates the hardening process, but also gives moisture resistance to the product.
- Superior Raw Brick with Straw It has light weight and good thermal insulation properties. In some situations, wood chips or dung are used instead of straw.
Molds for the manufacture of products
For the manufacture of a building type product, forms are needed. They can be different, for example, made with your own hands.
For the manufacture of molds, wood material is required, with the help of which the frame 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 illustrative example.
Attention
Such a formation is completely unsuitable for the industrial production of raw products. In this case, special equipment is used, which allows the production of products in large volumes. This equipment presses the material.
The formation of a mechanical type allows the material to be pressed to 20 tons. At the same time, more than 15 products of building material are manufactured. Such a number of raw element cannot be obtained at home.
Drying Stage
The drying process is one of the most important and responsible, therefore it is necessary to treat it with utmost care. In order to avoid moisture from entering the product during the drying process, it is necessary to construct an open type 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 the products are laid out under a canopy. The number of days is directly dependent on weather conditions. It is important to remember that bricks, after fully dried, are reduced in size by 12 percent. For flooring, it is best to use boards of medium thickness so that they do not bend under the weight of the raw elements.
In many cases, raw brick, the production technology of which is a complex process, has many advantages. After drying, building bricks can immediately be used in the construction of buildings.
Attention
The main value of the technology for the production of raw elements for construction is considered any trifle. At the time of making the clay mass solution, the exact composition of the future building material is important. The quality and characteristics of the products will depend on this. The drying process is best carried out in the spring season. This is necessary so that the planned construction of the house was ready for operation at the end of summer.
