The plant produces various types of bricks and label them depending on their properties. In this article we look at the most popular brands of brick , such as M100, M125 and M150. And decipher the meaning of these mysterious figures, and any differences between them.

The figure, which is denoted by the letter M (mark) will point you to the ultimate strength of the brick. In the markets you can find different types of bricks with stamps that range from 75 to 300. Of these, one can highlight the most popular - the M100, M125 and M150. Durability brick determines its location in the structure. The higher the index mark on the bricks, the higher its strength. That is why the bricks with the greatest strength is most often laid in the foundation of the building, and the main walls.
For the construction of private homes is considered ideal bricks M100. For high-rise buildings is better to use the brand M150 bricks.
On the strength values are not affected by what is Brick full or slotted.

If you have to build a house there are bricks of different brands can be the most durable bricks M150 put in the foundation of the house, bringing this so-called "zero" on the plates of the foundation. For the middle of the bricks fit with the lower strength of the brand M125, and on top using bricks M100.

Brand bricks set to the value of compressive strength and bending strength. Lime brick is divided into grades 75, 100, 125, 150, 200 depending on the strength limit of bricks. Determine brand bricks in terms of compressive strength, it is usually 7.5 - 35MPa.

Mark bricks (strength) is considered the main characteristic - is a special property of bricks repulse internal stresses and deformations while remaining intact. This indicator is denoted by the letter "M" and a number. The figure is the maximum load that can withstand a brick on a 1 cm 2 . For example, bricks mark 150 (M150) indicates that the bricks able to withstand a load of 150 kg / cm 2 . The strength index can vary from 75 to 300. The sale can often see brand brick M100, M125, M150 and M200.

 

Stability (brands) of bricks to frost.

The ability of any material to withstand freezing and thawing in vodonasyschennomsostoyanii called "frost".

By frost bricks also divided into certain brand but with a different designation: F15, F25, F35, F50 .
Stability of bricks to frost measured by certain cycles. When testing the product is saturated with water (kept in the water for 8 hours), the product is then placed in 8 hours freezing chamber - this is considered one cycle. Repeat this process until such time as the bricks does not start to change their characteristics in mass strength, etc. When this happens, stop the test and draw conclusions about the hardiness of bricks.

For buildings in Moscow is better to use a brick with resistance to frost for at least 35 cycles. That is why large plants try as little as possible to produce bricks with frost below 35 cycles. But the markets can be found brick with a low frost resistance, are brought from warmer regions. Such bricks low price, which attracts customers.
To after the construction of the house has not been any incidents, it is best to mark the future of construction bricks defined the specialist.

Our advice: do not acquire bricks at low prices, in which the rate of frost resistance 25, and then 15 cycles. For construction in the Moscow region is better to use a brick stamps F35, and then F50.

 

State standards (grades) brick.

In construction, as in any other sphere of our time there is a lot of new materials, technologies, developments and standards. And not all of these new products is absolutely simple and safe to operate. In order to streamline the collection of all these innovations, it was coined by the state standard (or guests). These standards spelled out all the rules and methods of work with certain materials. GOST - so say a sign of quality and compliance with all necessary standards and requirements. In every industry has its own national standards, and construction is no exception. Below we present you a list of guests who refer specifically to the bricks:

• GOST 530-2007 Ceramic brick and stones;
• GOST 530-95 Brick and ceramic stones;
• GOST 7484-78 Brick and ceramic stones facial;
• GOST 379-95 Silicate brick and stones.
