Types and properties of facing bricks

The choice of facing bricks is a topical issue. The range of such products is no longer limited only to classic white and red products (silicate and ceramic, respectively). In texture, color and properties, bricks can differ significantly. Ricol Building Materials Store offers a variety of options at competitive prices. To choose the optimal type of facing brick to solve a specific problem, it is necessary to study the characteristics of different models.

Perfectly smooth surface and high density is distinguished by hyper pressed brick. Because of these characteristics with masonry mortar, the adhesion strength is relatively low. Small recesses or through holes simplify the installation process of such material. The characteristics of the masonry will be higher. You can also use a “young” brick, with hydration processes that have not yet been completed. With the cement of the masonry mortar, the “free” cement that is present in the brick itself will react in this case. It should be borne in mind that less than five percent of the particles capable of such reactions remain in the brick after twenty-eight days of hardening.

The advantages of solid bricks

When buying hyper pressed facing bricks, it is better to give preference to freshly made products. Each batch of goods is accompanied by a factory liner, which indicates the date of manufacture.

Hypressed brick has some features. In particular, after reducing internal stresses, microcracks may appear during a certain period of operation. They do not pose a danger and are almost invisible at the initial stage of formation. Such cracks will increase when exposed to moisture, freezing cycles and thawing it in seasons. Facades made of such material for this reason are recommended to be additionally hydrophobic.

Even worse resists the destruction of the material having a textured surface. On special equipment, solid products in this case are split to imitate the texture of natural stone. Microcracks are obtained as a result of blows in the thickness of the brick. Only effective hydrophobic can solve this problem.

Facing ceramic bricks are in great demand. When planning such a purchase, you need to take into account the high moisture absorption of the material. It can reach twelve percent of the mass. The microclimate of the house is beneficially affected by vapor permeability, which occurs due to communicating pores. But it is she who becomes the cause of moisture absorption. In order to avoid premature destruction of the finish, it will also be necessary to take protective measures.
