Brick is a serious matter

To date, only 2 types of bricks are produced – silicate and ceramic. Their difference lies in the method of production, standards of size and shape, color and texture.

Since the varieties of this building material have different properties, before their choice you must first determine the purpose of application. In addition, the prices for the brick also vary. Classic (ceramic) red brick recognized as universal. It is ideal for both laying the furnace, and for walls and even the foundation. Silicate brick is more fragile and is quickly destroyed when exposed to high temperatures, humidity or open fire. This brick is categorically not suitable for the construction of furnaces, fireplaces, chimneys, supporting supports and pools.

When choosing a brick, its technical characteristics should be paid first of all:

one. Resistance to deformation. As a rule, all bricks are marked. The label with the letter “m” and numbers indicates the maximum load that this material can withstand. For example, if the M150 mark is worth, then this means that 1 Brick withstands a load up to 150 kg.

2. Frost resistance. This is a very important characteristic that should certainly be taken into account if you plan to use brick for outdoor purposes. The degree of frost resistance is indicated by the letters “F” (or “MRZ”) and is calculated in the so -called cycles. By the way, this indicator can directly affect the cost of the material. As a rule, the cheapest brick usually has a low frost resistance indicator-15-25 cycles. For the northern and central regions, an indicator of at least 35 is desirable.

3. Another important point. There should not be traces of negative lime in the rudder of red bricks. Their presence indicates that this material has very low quality and will not last long. A similar disadvantage is the unfinished brick. It has a dull sound and mustard tint. As a rule, a vulnerable place of such brick is low moisture and heat resistance.

On the other hand, the burnt brick is quite applicable, but it is necessary to make sure that its shape is not broken, and the core was not too black.
