The brick is material without which it is impossible to do in construction. Especially, if it is about constructions for heating, such as furnaces and fireplaces, then when choosing brick it is necessary to pay special attention to fire resistance of material.
Construction of the furnace or fireplace – action very responsible as it is not just about interior parts, and about the constructions intended for heating of the dwelling. Let now this function of the furnace or fireplace be also not the main, such heating constructions remain fire sources that forces to impose certain requirements to them from area of fire danger.
How to choose brick for laying of the furnace or fireplace
That the internal structure of the room made by you did not become cause of the fire, it is necessary to approach the choice of construction materials responsibly. The main material on which reliability and functionality of fireplace or the furnace depends is the brick. For fire resistance of fireplace or the furnace where there will be naked flame, it is necessary to use refractory brick or, so-called, "shamotny" brick. When choosing it is desirable to consider attentively each block of material, checking its quality. To estimate quality of material, it is optional to have vocational education, it can make it to each person.
How to determine quality of brick by its color
The good refractory brick has to have bright red color which is evenly distributed on all surface. If inside brick black, it means, that it burned through therefore it is not suitable for construction of the furnace or fireplace, however it can be used when building various constructions.
What clay it is better to choose
As binding material at laying of fireplace or the furnace clay therefore it is necessary to approach its choice with the same gravity acts. Clay happens three types: greasy, average and lean. In rich clay the volume of impurity of sand is 10-12%, in average – 12-33%, and the clay consisting of sand more than for 33% is called lean. For construction of fireplace or the furnace the rich or average clay is generally used. The higher in it sand content, the it less fire-resistant, at the same time is high the probability that in one "not wonderful day" all design will just fail because the feature connector of laying has not sustained continuous influence of high temperatures. In old times of the master checked clay, kneading it in hands. Good clay should not stick to hands. If you correctly choose suitable materials, future design for heating of your house will turn out the strongest and reliable and also will serve not one decade.
