Which brick is better - silicate or ceramic? The use of bricks has a rich history spanning several centuries. The first types of bricks were made from clay and burned in kilns. At that time, the variety of unpretentious building material was provided only by the use of different types of clay. Uniform standards did not exist at that time, and each of the manufacturers did as it suits him. But at that time, low buildings were being built, and therefore there were no big problems with the use of ancient material, especially since there were no alternatives at that time.
But now the variety of building materials cannot but rejoice, and in this regard, the question arises - which brick is better, silicate or ceramic?
In order to correctly figure out which type of building material is worth buying, you should familiarize yourself with the main parameters of the two types of blocks, and also in which cases it is better to use the first or the second, since each of them has its own strengths and weaknesses. With a careful study of the technical characteristics, you can figure out how ceramic bricks differ from silicate bricks, as well as make the right choice and use both materials only for their intended purpose.
When the mass construction of high-rise buildings began in the early 20th century, it was silicate brick that was widespread. Its main difference from ceramic is the aggregate bonding technology.
Good advice! The quality of these two materials depends primarily on the raw materials used, so try to focus on products from popular manufacturers.
Before that, the manufacturing technology was many times simpler, and it did not take as much time as it did for the manufacture of ceramic building material. If the creation of a batch of ceramic-type bricks took about a week, then a batch of silicate of a similar volume could be obtained in less than 24 hours.
For comparison of silicate and ceramic bricks - for the first type, no special components were required, and the main components were lime, sand and water. With the current production, a few binders are added, which significantly improve the technological characteristics, and this almost does not affect the cost.
In modern construction, you can find more and more building materials with improvements in terms of technological characteristics, but silicate and ceramic bricks do not go to the last lines. They are used as before in the construction of walls and cladding.
At first, it may not be clear which of the two types of stones to choose for building your own home, and it is also difficult to understand whether silicate or ceramic bricks are better.
At the price, buyers are attracted by the first option, since it is almost two times cheaper than the analogue of the ceramic type.
To make it easier to understand, let's compare the most basic qualities:
For the sake of completeness, compare the indicators of both materials, and based on the information received, it will be possible to conclude which of the two types is better. Note that the strength of both types is quite high.
Silicate is better than ceramic in its density. So, the weight of the first single block varies from 3.4 to 3.
6 kg, while the one and a half weighs up to 4.4 kg. Hollow types weigh a little less, but the load on the base will still be high compared to laying ceramic bricks.
In terms of heat resistance of silicate material, we note that it can withstand up to +600 degrees, at higher temperatures the stone will collapse. Because of this, silicate is not used when laying stoves, chimneys, fireplaces and other structures that get very hot.
In contrast, ceramic bricks will give good heat resistance, especially if you choose clinker bricks. It can perfectly replace its silicate counterpart when laying the above structures. In addition, a ceramic stone has a fire resistance of up to 6 hours, while a silicate brick can withstand a maximum of 3 hours.
The index of frost resistance is important, especially if we take into account our climate with a large amplitude of temperatures and indicators of the mercury column in frost. On the stone, the frost resistance indicator is marked with the letter F and a value is written that corresponds to the thawing-freezing cycles without losing the original qualities.
The silicate value ranges from 15 to 35, but in the past few years, thanks to special additives, it has been possible to reach the F50 value.
The ceramic analogue is much better in these indicators, since in the standard version it is F50, and the clinker brick has frost resistance F100. Naturally, if you live where there are frosty winters, it is better to use ceramic bricks. If you live in the south, arrange sand-lime bricks.
If by these criteria we evaluate which brick is better - silicate or ceramic, then silicate stone wins here.
Even if the silicate is completely dehydrated, its coefficient of thermal conductivity is between 0.4 and 0.7 W / M8K. With aging, the indicator slightly decreases to values from 0.55 to 0.
94 W / M * K. For facing ceramics, the thermal conductivity coefficient can be from 0.33 to 0.58 W / M * K.
Please note, that the walls, built of ceramic bricks, retain the heat of the house much better, which makes it possible to save on heating.
If additional thermal insulation is needed when building silicate walls, try using hollow ceramics for cladding, which will help preserve valuable heat inside the house. The main advantage of ceramic stone is that it hardly gets wet in rain or snow, and the heat conductivity index will not change from the weather. And for silicate bricks, this is a weak side, since when wet, the thermal conductivity becomes higher, which means that with a high level of humidity, the brick will give off heat from the house much faster.
Another serious problem with silicate blocks is the high level of water absorption, approximately 11 to 13%, and in addition, due to the method of production, its own moisture is 18.5%.
It draws water easily, so there are a wide range of restrictions on its use.
It cannot be used for the construction of a basement, basement, bathhouse, shower room, laundries and saunas, therefore it is successfully replaced with ceramic bricks. It almost does not absorb moisture, so that fungus or mold never forms on it. Water absorption from 7 to 14%, and when using clinker bricks only 3% maximum. If there is a need to use silicate bricks for exterior decoration, use a treatment with a special water-repellent solution (water repellent) to reduce water absorption.
According to these indicators, everything is on the side of ceramic bricks.
Thus, it is difficult to choose which brick is better - silicate or ceramic, since each of them has its own advantages, disadvantages and the right to use. With knowledge of the technical characteristics, you can avoid mistakes and make the right choice. The result of the choice will be a beautiful and reliable home that will serve for many years.
