What should be a ceramic brick according to GOST?

Brick is one of the most ancient building materials that is strong and durable. At present, in order to comply with all parameters, its production is regulated by GOST No. 530, which regulates recommendations and instructions for both consumers and manufacturers.

If such information is available, then you can protect yourself from buying a low-quality product, as well as choose the optimal product for certain needs.

All ceramic bricks, both facing and for construction purposes, are made according to the standard.

Such material differs in composition:

• high strength characteristics, which allows it to withstand heavy loads and makes it possible to build foundations from it;
• resistance to negative external factors;
• the ability to withstand high temperatures.

Currently, there are the following types of bricks.

• Private single... An ordinary brick, which has no voids, is inexpensive and is not decorated in any way. It is the most common.
• Corpulent... May have one or more voids.
• Hollow... It has many voids of various configurations and sizes.
• Façade... It is produced in any shape and geometry.
• Clinker... A durable material that is used in landscaping and as a decorative material. The parameters correspond to the standard ones, but, if necessary, they can be produced in various other forms.
• Facial... Refers to decorative materials and has characteristics similar to conventional bricks. It has strength and at the same time has a decorative base.
• Ceramic block... Has a void inside, is large. Designed for masonry walls.

Brick is a ceramic material, as it is made from clay and then fired. Usually it has the shape of a parallelepiped with right angles, and its standard dimensions are 250x120x65 mm. Also, bricks are additionally marked in accordance with the strength, which is indicated by the letter "M".

For facing materials, not only quality, strength and compliance with standards are important, but also a beautiful appearance. Therefore, such products may have the following side surfaces: textured, glazed, with a relief.

Such requirements are not imposed on ordinary bricks, and therefore they usually have smooth surfaces, and the color can be different, depending on the type of additives used.

Ceramic materials, like any other, are characterized by their strengths and weaknesses.

The benefits include:

• high density and strength indicators;
• frost resistance;
• fire resistance;
• environmental friendliness;
• a large assortment;
• the ability to do masonry with your own hands;
• aesthetic qualities.

Minuses:

• fragility;
• the appearance of efflorescence;
• the need for skills when laying.

Bricks are packed in foil or other material that protects the product from external factors and atmospheric influences.The bricks are stacked on pallets and labeled depending on the number of units in the bundle. Storage in open areas is also allowed, taking into account the seasonality.

Transportation is carried out by any vehicle in compliance with regulatory requirements. In this case, the products are secured appropriately to prevent them from falling.

When buying or ordering such material, you must take into account some rules.

Here are the prerequisites:

• bricks must comply with GOST and have certificates;
• the quality of the building stone must be reflected in the necessary accompanying documents;
• the batch cannot contain defective products;
• the documents must contain the address of the manufacturer, the batch number, as well as the grade of strength, density, level of water absorption, frost resistance, and other parameters;
• in the production of bricks, it is mandatory to undergo tests, the results of which are indicated in the certificate.

In order to avoid mistakes and not to purchase low-quality material, it is recommended to pay attention to:

• brick appearance and color uniformity;
• the presence of mechanical damage;
• the presence of irregularities and chips;
• presence of a certificate.

It is worth abandoning the purchase of handicraft bricks, since the low cost can cause a short-term operation of buildings and entail the need to purchase an additional batch of bricks.

As you can see, GOST for brick is useful not only for manufacturers, but also for buyers. If you own the above information, you can protect yourself from buying low-quality products and at the same time purchase the optimal type of brick that is suitable for certain purposes.

In some cases, according to GOST, a deviation of geometric parameters is allowed, but they should not exceed the norm, which is 1-2 mm.

Such indicators are compared with the dry weight of the brick and recorded in the documents.

If it is necessary to erect multi-storey buildings, it is worth paying attention to the strength of the brick. To do this, it is placed under a press and exerted a certain load, up to its destruction. The more weight the brick can withstand, the longer it will last and stay in the masonry.

It is also important when designing objects where bricks will be used in the form of a building material, initially to be determined with frost resistance, density and other parameters of products, which will help them to stand in the wall longer and not collapse. All these points are prescribed in the documentation for the product, and the requirements must be strictly followed by the manufacturers.
