The construction of a private house is a responsible business, therefore the owners of the site provide for all the nuances, calculate the amount of materials, the load on foundation, laying of communication systems.
Before purchasing building materials, experts advise you to familiarize yourself with the technical characteristics of each of them, the peculiarities of operation in a particular development region, and based on the knowledge gained, make a choice.
Silicate facing brick, for example, has been used for many years, and has excellent qualities due to which it does not lose its popularity.
The appearance of the facades of the house is something that cannot be saved on. Much depends on how attractive the building looks.
First of all, this affects the opinion of the neighbors around you. In addition, the owners of the house will contemplate their possessions for a long time and notice shortcomings, if any. The approach to the choice of exterior wall finishes must be deliberate and carefully considered.
Silicate brick is in many ways superior to the known ceramic.
It has characteristics that make it a leader among finishing materials:
Note. The outer side of the facing brick, which is laid on the base of the facade, is treated with a special solution that increases the resistance to moisture.
Without waterproofing impregnation, the material is exposed to the destructive influence of water. As a result, there are erosive areas, face chips. The surface loses its original smoothness, becomes rough and rough.
Pores appear on the brick, into which dust and dirt are clogged, causing the material to acquire an earthy unpleasant hue. Often, facing silicate bricks for outdoor decoration, which are located in the upper masonry and are closed from the sun by the roof arch, are subject to such processes.
The material must have a smooth surface, without damage, cracks, dents, bulges and other defects. The main principle of creating high-quality sand-lime bricks is the correct geometric shape. All edges must be clear and even, without roundness and overlapping areas.
Any damage to the outside of the brick will spoil the appearance of the product and reduce the decorative function.
Types of material, taking into account the density:
Hollow silicate brick has cavities formed during production, it is used for facing the facades of buildings. Due to its low weight, the finishing process is not difficult. In addition, the material does not significantly load the foundation of the house. Artificially created voids help keep the walls warm.
Monolithic brick is much stronger than the previous type, but at the same time it has more weight. This causes some installation difficulties, and the cladding facades put pressure on the base of the house. The advantage of the material is its excellent resistance to frost.
GOST standards determine the dimensions of silicate bricks:
Produced with voids inside, the weight of which is 3.
2 kg. Solid sand-lime brick weighs 3.7 kg. The products have the same dimensions: height - 65 mm, length - 250 mm, width - 120 mm. The weight of silicate bricks is one and a half hollow 3,7 kg, solid 4,2 - 5 kg.
The block height is 88 mm, and the width and length correspond to the single version.
They are produced hollow, since the blocks are quite heavy - 5.4 kg. Dimensions: length 250 mm, thickness 138 mm, width 120 mm,
Manufacturing enterprises accept orders for the manufacture of blocks of non-standard shape. For example, there are bricks that are used to decorate arches, rounded elements.
Silicate facing bricks have characteristics similar to those of ordinary ordinary wall materials. But given the increased requirements for product quality and the high cost of material, it is irrational to use it for building houses. In this regard, silicate blocks are used to decorate facades.
Standard blocks are produced in white or discreet pastel shades. The white version is attractive in that it can be painted with special tint impregnations, subject to finishing with moisture-protective agents.
The color palette of the material is rather scarce, since there is lime in the mixture for manufacturing. This suggests that alkali-resistant minerals are used as pigments.
Silicate bricks are tinted in such colors as:
Note. For each shade of sand-lime brick, the color of the cement mortar is selected.
In the process of absorbing moisture, the material changes color.
In addition to the front one-and-a-half silicate brick with a smooth surface, there are options with a corrugated surface on the building materials market. Such options allow you to give facades a special zest and appeal.
Embossed brick imitates natural stone, for example, antique chipped. On sale there is a material resembling oak bark, which is perfectly combined with brown and red bricks.
Plant motifs are presented in the form of an imitation of a reed. On the surface of the brick, the sticks of a brown plant are clearly visible. Another variant of an interesting texture is called a turtle, the relief of which resembles a turtle shell.
Facing silicate bricks have the ability to keep their shape and relief, which makes it possible to create mosaic panels. To maintain the decorative function, solutions and protective mastic of a certain color are used.
The cost of colored and textured silicate facing bricks according to GOST is slightly higher than ordinary white with a smooth surface. Due to its high density, it weighs more, actively absorbs moisture without being treated with waterproofing agents, and has a low level of heat and noise insulation. but, in comparison with the advantages of the material, this disadvantage is not so significant.
Facing silicate brick has a high level of environmental friendliness and does not emit toxic substances hazardous to human health. During the production of the material, a study of sandy raw materials is carried out for compliance with GOST standards.
The decorative value of silicate-based bricks is higher than that of ceramic bricks. In order to make the facade of the house look more attractive, various combinations of color and texture of materials are used in the finishing process. The play of shades makes it possible to visually make the house higher, to highlight individual structural elements.
The first step is to form corners in several rows. To create them, use the building level.
The masonry is completed with a furrow imitating steps.
A cord is pulled between the corners, and the ends are fastened with nails, which are driven into the seam formed during the creation of the corners. The jute should not sag, but it should not be too tight. In order to determine the evenness of the foundation, a level is substituted under the cord.
If you find a slope, a number of actions should be taken to eliminate it:
Note. The seams of the laid sand-lime bricks are tied with bars, which are laid in each subsequent row.
After leveling the masonry, begin facing the building facades with silicate bricks.The mortar must be thick, otherwise it will leak out of the seams. As a result, you get an unaesthetic-looking wall.
After the cement mortar has set, the so-called jointing is carried out. This allows them to be compacted and to give the facade an attractive appearance. This process can be carried out in different ways. One of them involves removing excess mortar to obtain an even seam. The second method is aimed at shaping a semicircle or rectangle.
In the process of laying one-and-a-half hollow silicate bricks on the facade, care must be taken not to form recesses and bulges.
Considering that the material is made from natural components, plastic bags are used for its transportation. The blocks are placed on a pyramid-shaped support and fixed with cables. The technical features of silicate bricks make it possible to use it in different areas of construction. At the same time, it is important to carry out insulation work, especially in regions with severe climatic conditions.
