Brick today is one of the best and most common building materials. It is used by both private builders and professional companies. There are small and large enterprises that manufacture and sell these products. You, too, can create your own business that will satisfy your requirements, as well as become a source of income. However, to obtain high-quality brick, it is necessary to comply with the technical conditions and adhere to the manufacturing process. The production of bricks at home does not imply the use of expensive equipment. The most important condition is the proper preparation of raw materials.
Manufacturing Features
Forms can be boards that are previously strayed together. Subsequently, raw materials are placed in them. It is necessary to make molds of such dimensions that the finished product matches the dimensions and appearance of the traditional brick, which has dimensions within 25x12x6.5 cm. The lid will allow tamping of raw materials that fit into the molds. Brick production will be faster if several patterns are made.
Technology of work
The inner side of the mold must be moistened in advance or sprinkled with dry cement. Next, the prepared solution is laid. As you fill out the form, you need to ram the mixture so that all corners and voids are filled. Excess mortar should be removed with a spatula. Next comes the turn of the lid, which is stacked on top. At the next stage, a certain time is expected, after the expiration of which you need to turn the form over and take out the semi-finished product. The room should be equipped with shelves under a canopy, on which to lay a brick for drying. Natural shrinkage will occur within 15%. At this stage, water evaporates. This becomes a catalyst for the convergence of substances in the mixture.
In this case, exposure to products in direct sunlight should be excluded. The production of bricks is carried out in a room that is well ventilated. Drying lasts from 7 to 14 days. It must be remembered that the manufacture of bricks without firing is one of the fastest and easiest methods for obtaining the described building material. As the only, but important drawback, it is considered that the resulting products can only be used to form partitions indoors. This is due to the fact that humidity can have a destructive effect on them.
Raw Use Area
It will be possible to use raw when arranging partitions and walls, which will be located inside buildings. This can be buildings, as well as baths, which are used for economic purposes. However, in this case, it will be mandatory to carry out waterproofing from the inside. You can use this material in the construction of capital walls in buildings that have one floor. In this case, the roof should be wooden.
Brick firing
The production of bricks at home involves the next stage of firing. This will allow to obtain high-quality building material. In industrial enterprises, special furnaces are used for this. Whereas in case of self-production, you can build a product that is made from available materials. To do this, in the ground should prepare a recess up to 0.5 meters. Above it, with a deviation from the bottom of 20 cm, a metal barrel should be installed, which is devoid of a bottom. In the walls of the tank, make holes in which the fittings are installed. On the resulting shelf, you need to lay the semi-finished products that have been pre-dried. The barrel is covered with a metal sheet on top. In a prepared depression, a fire should be built.
Firing nuances
Brick production technology requires compliance with a certain temperature regime, so that the finished product turns out to be of high quality. During the first eight hours, you should keep the temperature within 200 degrees. The firing process is carried out from 12 to 16 hours, during which the temperature must be kept from 800 to 1000 degrees. The next 4 hours, the temperature regime should be gentle, from 500 to 600 degrees. Gradual adjustment of the temperature will allow you to get the desired result, eliminating the occurrence of cracks. You can make a fire with coal or firewood. The filled container should cool with a well-closed lid. Only after that it will be possible to release the brick, checking its readiness.
Making a lot of bricks
Installation for the production of bricks, or rather for firing, can be intended for a more impressive number of building materials. For this, a furnace is equipped using a tank. Its shape should resemble a design narrowed up. Raw material is laid in it, covered with sand or soil to provide thermal insulation. After the fire is lit inside, and the temperature should remain the same as the one described above. The production of hyper-pressed bricks is also possible at home. To do this, you will need to use a special machine that compresses the prepared mixture into a denser mass. For work there will be no need to use electricity. Then the process will be quite simple.
Alternative brick options
Clinker brick production involves the use of somewhat more sophisticated equipment. The products are formed using semi-dry pressing technology. At the same time, there is an opportunity to save electricity. In production, a vacuum press is used, which is sometimes replaced by a lever press. In some cases, wizards use a tape installation. After the formation of the workpiece, the brick enters the dryer. For this, special electric fireplaces are used that maintain a high temperature. Refractory clay acts as the most important raw material ingredient. It is characterized by plasticity and a high temperature threshold. When preparing the solution, metal oxides or minerals, which belong to the group of kaolins, are added to the ingredients. This allows you to get stronger products.
Ceramic brick making
The production of ceramic bricks at home involves the preparation of raw material, its formation, as well as subsequent firing. Clay mined in a quarry is not suitable in its original form for the formation of high-quality bricks. The mass is brought to readiness, during which processing measures are carried out. This can be a natural or mechanical effect. At the drying stage, the percentage of moisture content in products decreases to 6%. Such an indicator is needed so that cracks do not form during firing, and the finished product does not deform. If chamber dryers are used, they will be able to provide temperatures ranging from 120 to 150 degrees. Depending on the moisture content of the raw material, as a rule, this stage takes no more than 3 days. The final stage is firing. For its implementation ring or tunnel kilns will be necessary.
Silicate brick making
Silicate brick production involves the use of autoclave synthesis. In order to produce one unit of material, 9 parts of quartz sand, which is pre-screened, additives, as well as one part of airy lime , will be needed . The last component must be special.
