Facing bricks and its characteristics

What is a face brick?

building block made of clay or high-grade cement and called the people (and officially) brick has three surfaces.Basic two planes, one of which building (or finishing) the block is placed on the mortar, and the second layer is applied to a new solution, called a bed.

short lateral face poking called, perhaps because it briquettes pinned down at each other at facing or in a half-brick masonry.Long lateral face is called stretcher.All side faces are facial and have extremely flat and smooth surface.

This material has different compositions. the main components face brick is divided into a ceramic, silicate and silicate, and according to the method of production - on hyperpressed and clinker .Ceramic building and facing blocks made of clay, which is baked in special ovens tunnel or ring-type at a temperature of 1200 degrees Celsius.Silicate

building blocks made of lime, which is composed of not less than 90% and the sand (approximately 10% including a small amount of additives) silicate has an additional component - aluminum powder which reacts with water and calcium hydroxide.

Brick front - size, color and shape

on a standard size building blocks are divided into a brick front single, one and a half, double (250h65h120, 250h88h120 and 250h130h120 mm, respectively) and the euro, but if the first three are consistent with their names,the last option is very different from them.

This option is also single and one and a half, and the first has dimensions 250h65h85 mm, and the second - 250h88h85 mm, ie the Euro-brick front with respect to the size of the thickness is smaller than the standard.The thermal conductivity of it, of course, below, but in a much more units per cubic meter of cladding material, which is undoubtedly advantageous for quality weatherization home.

thermal conductivity of brick depends on its density, and, because it is the ceramic is 0.45 W / m ° C, and in the silicate - 0.7 W / m ° C, it is not difficult to guess that the last 2 times worse retains heat.

Now back to hyperpressed and clinker, which we absolutely did not say anything earlier.The first one is very interesting, although its thermal conductivity is too high.Since it is made by dry pressing, added to the composition of the dyes retain vivid colors.As a consequence, these bricks can be a variety of colors and shades, in fact, is the only option if you want to trim in unusual colors, such as blue or green.

As for clinker bricks, then they can be non-standard form.Semicircular or with two semicircles at a spoon, trapezoidal and triangular, such bricks can turn your home into a work of art, consisting of interlacing arches, columns and curved eaves.

Brick corpulent face, hollow and with recesses in their beds

Ceramic building block has a low thermal conductivity, silicate - high strength, what do you choose?It would seem that the second, but if it is full-bodied brick front, then it will weigh about 8 kilograms.Agree to work with such a weight - a little pleasant.Another thing, if done voids in the building block, then he becomes at least 2, if not 3 times better.

Void needed for another reason.The fact that the denser the building block, the smoother the surface, without surface roughness and adhesion to the cement mortar is unimportant.Void and recesses in the bricks beds provide excellent grip lock. important to know that if the building block is made of cement, with him will be a maximum adhesion solution only if the so-called "young" brick taken out of the form, not later than a month ago .

As it turned out as a result of repeated inspections, artificial stone masonry at the end of 28 days cured so that its surface is almost no particles do not come into the hydration reaction.This means that communication with the solution will not be as strong as if loose particles, at least in an amount up to 5% of the total weight, remained on the bedding surface.
