Pros and cons of the construction of the ceramic bricks
Made of natural clay ceramic bricks, the pros and cons of which we are examining today, has long been a popular material for building walls.Today, he still does not give up its position - the consumer appreciates its environmental friendliness and reliability.Brick building strong, warm, and can stand more than one hundred years - the test of time.

Familiarity with material
Before we look at the pros and cons of ceramic bricks need to understand what kind of material and what properties it has.The basis of ceramic bricks is clay mass.The finer and more uniform her faction, the higher quality the product is obtained.Best clay getting shovels, which is able to get her out of a single layer, without mixing with others.This requires a special career, it has become
In this case, the excellent result achieved by the correct firing.The molded mass is put into a furnace with a temperature above 900 degrees.This fusible components of clay hold together those that melt over a long time.The ratio of these components may be different - it affects the structure of the product.During their manufacture, it is important to observe all the rules as in forming and during drying.
Species, size and brand of ceramic bricks
There is Adobe (otherwise, adobe), which is simply dried in the air.But it is now virtually do not, so let's talk about the baked product.All of the parameters must comply with GOST 530-2007 and GOST 7484-78.
Ceramic brick intended
series (or building) brick wall spread inside and outside homes.This type of brick, can be solid or have a void.
soldier ceramic bricks.
have facial (otherwise facing) bricks are increased requirements to the outer edge.It has to look good and be of high quality, able to withstand rain, sun, cold.The surface of these articles can be smooth or grooved.Also used staining.Bricks that are used in outdoor applications of any type, including the restoration and wall.
Facing ceramic bricks.
Special varieties of bricks used in special circumstances.For example, fireclay bricks needed for fireplaces and stoves.Make it special with the addition of clay - grog.Calcined before losing its plasticity, and then pulverized.
What is the ceramic brick structure
The structure ceramic brick can be solid and hollow.
brick called a durable one-piece product without holes.Its weight - from 3 to 4 kg, and the thermal conductivity - from 0.45 to 0.8 W / m · ° C.For the construction (especially low-rise), it is used less and less, but there are times when no monolithic brick can not do.For example, when laying the stove or fireplace, as well as foundations, basement walls or pier.Yet it is necessary for the manufacture of strong internal partitions and load bearing walls.
corpulent ceramic brick.
brick called the product, riddled with holes (round or square).Often they are made through.One brick weighs between 2 and 2.5 kilograms, it is less than the thermal conductivity (0.3 to 0.55 W / m · ° C).Internal cavities can be from 15 to 55%.This material is suitable for the construction of exterior walls and three floors, the internal light baffles.
hollow ceramic brick.
dimensions of ceramic bricks
product may be single, double or bastard.And in the last two cases, the bricks must have emptiness.Standard length (otherwise stretcher) is 25 centimeters, and the width (called poking) - 12 cm. This is useful for laying, as the two widths, plus mortar seam up long.
differ only in height:
- Brick SF 1 (single) - 6.5 cm;
- Brick 1.4 NF (bastard) - 8.8 cm;
- Brick 2.1 NF (double) - 14 cm;
Bricks, got 0.7 NF marking (except "Euro") we used less frequently.Their height is the standard 6.5 cm, but somewhat reduced, and the width is 8.5 cm.
There are modular, single products (1.3 HF), which also have a standard height of 6.5 cm, and the other dimensions of more solid(length - 28.8 cm, width - 13.8 cm).
What brand of ceramic bricks manufactured
Labelled brick with the letter "M" and the numbers from 50 to 300. They are characterized by the maximum permissible pressure in an environment where the product affected by just three forces.This tension, compression and bending.This pressure is measured in kilograms per square centimeter.The higher the value, the stronger the bricks.
M 50 products are suitable only for small fences and walls.Walls (any other than carriers) may put marks M75 and M100.If you want to fold or arch bearing wall, you will need to purchase brand products is not lower than M125.Plinth foundations laid brick M175, M150 and more durable.
Pros ceramic bricks
+ variety of colors
addition to the traditional red, can be called a peach, chocolate, beige, yellow and various shades of them.Especially rich colors at the bricks - because it is often still stained.
+ variety of shapes and sizes
As mentioned, in addition to the single, there is a double, one and a half brick, as well as additional variations.
+ Masonry is straightforward
masonry of ceramic bricks is not very complicated - most importantly, to acquire basic skills.
+ Long life
Good performance on the strength of the building made of brick rather durable.
+ Environmentally friendly material
Clay - an eco-friendly material, so bricks are made from it, are safe for humans and the natural environment.
+ Have soundproofed
brick walls muffle noise well.
+ good indicator of thermal conductivity
ceramic bricks nice retain heat (the latter quality is especially true for hollow articles).
+ Low price
ceramic bricks have a low price (for example, compared with clinker).
Cons ceramic bricks
- There are articles with incorrect geometry
Sometimes the geometry of the product is poor, which is why masonry becomes difficult (it is on the conscience of the manufacturer).
- may quickly fail due to poor-quality raw materials
When poor-quality processing of raw materials limestone, which is always present in the clay remains in mass for bricks.Then jump in brick "Quilted".In these places, the product absorbs moisture and greatly destroyed.
- Brick could crumble
Pottery may crumble due to the wrong choice of a solution or a product brand (insufficiently high strength).
- easily damaged during transportation
During transportation to the place of construction bricks may be damaged - he break off the edge - you have to reject the material.Most often this happens with inexpensive varieties that shift along only.
- High water absorption
water absorption ceramic (especially porous products) is quite high - up to 10 percent.Because of this reduces the number of cycles of freezing and thawing.
- appearance of efflorescence
on a brick wall with time may appear ugly whitish stains - efflorescence.Often such trouble due to chemical corrosion - when the house is near a chemical plant, for example.Or in the bricks "chemistry" is added.
One of the causes of the efflorescence are additives chemical components in the raw material for the production of ceramic products.At the same time and on the ecology is uncertain.
As you can see, some of the downsides of this material is present only in the production of unscrupulous manufacturers.When the raw materials, for example, poor.Or the technology is not respected.So choose ceramic brick cautiously and carefully, buying it from reliable suppliers and manufacturers.
