Why does the red brick crack
Red, or ceramic brick, despiteits centuries-old history, it's not going to leave construction sites and is in great demand when doing construction work. He is handsome and light, but for a long service and preservation of attractiveness he needs a number of conditions.
The attractiveness of ceramic bricks
Red brick is attractive in its classicelegant and, of course, at an affordable price. Currently, mostly red brick is used for decorative decoration of buildings, it is often found in the construction of cottages and monolithic-brick houses. Also, ceramic bricks with respect to silicones absorb moisture much less, and, as is known, the presence of moisture in this or that material leads eventually to its destruction. However, ceramic bricks also have their drawbacks: over time, with improper laying and exploitation of the building, it can crack. Saturation with moisture
Despite the fact that the red brick is madeclays, in which there is a low composition of coarse-grained elements, this material is designed to reduce the absorbency of moisture in the structures constructed from it. The main reason for the cracking of a brick is its saturation with moisture, which then, under the influence of climatic phenomena such as heat and frost, expands in the natural cavities of the material, literally tearing it from within.Lack of finish
Many people think this is strange, but not onlyperforms decorative functions, but also protects brick walls from destruction. Builders know that the building box should in no case be left to the winter "unclosed." The inside of the house will provide your brickwork with the necessary shrinkage and strength.Quality
Another reason for crackingBrick, even with all the conditions of masonry - this is his factory marriage. For example, in order to economize the factory for the manufacture of bricks can take a large granular clay, which is strongly discouraged for the reason that this clay, after processing the brick in the furnace, leaves large cavities in it, into which moisture enters. Most often with a violation of production technology The brick gives large longitudinal cracks, and the whole batch "bursts". Usually, when such marriages are detected, a construction expert examination is appointed, which gives an opinion not only about the quality of the brick used, but also about the possibility of further exploitation of the structure from it, because the bursting of the masonry significantly reduces the load-bearing capacity of the structure as a whole. Modern materials and chemical catalysts for the most part played a cruel joke on building materials. Yes, they significantly speed up production, make it cheaper, but at the same time the quality of the product suffers. The brick of natural roasting, which was used in the 18th-19th centuries, is much more stable and reliable than the modern one.
