Silicate brick has been used in construction for quite some time. He established himself as a fairly comfortable and durable material for the construction of buildings. Like any other building material, silicate bricks have advantages and disadvantages. The first is much more. That is why this building material is widely popular, and we will tell how to put a silicate brick independently.
Characteristics of silicate brick are ambiguous
This type of brick consists mainly of quartz sand. It also includes lime and other additives, but their share is insignificant. Make it by pressing dry. Then douse with water vapor. Silicate brick weighs 4 kg and has the correct shape. Durability depends on the brand. In addition, it is of different types: for personal work or ordinary. Due to special additives silicate brick can be of several colors. If desired, you can find a brick of various forms.
Various buildings are erected from silicate bricks, up to multi-storey buildings. This building material is an excellent sound insulator, so it is often used in the construction of interior walls. He is a veteran in the construction market. Actively began to produce it in Soviet times, but thanks to the mass of positive properties, it is widely in demand now.
There is no difference in the technology of silicate brick laying from ordinary brick laying. When laying use the same rules.
The weight of silicate brick is an order of magnitude greater than that of its “relatives” of other species. Due to this, the strength of the erected structure increases. At the same time, the price of such a brick is much lower. This results from the fact that time for its production leaves less.
Another important advantage is that silicate brick and its buildings are safe for the health of people living in it. It is noteworthy that the fungus does not form on the surface of such walls.
At the time of Khrushchev, buildings were erected exactly from silicate
The disadvantages include instability to strong frost - the house of silicate brick will have to be insulated additionally. When building multi-storey buildings, it is better to choose another material. It is also not recommended to lay it in the foundation, to put fireplaces or stoves out of it. This type of brick collapses from high temperatures. The constant impact of groundwater containing salts adversely affects this type of brick. Use it when laying the foundation is possible only with high-quality abstraction of groundwater.
Preparation of mortar for masonry bricks
There are several ways to prepare a mortar for sand brick masonry. It is used in order to avoid the displacement of bricks relative to each other. The easiest way to prepare is cement or lime and sand. The first components act as a binder. They are sometimes replaced with clay. Sand use medium fraction. The solution is prepared as follows: three parts of sand are added to one part of the cement. The resulting mixture should be quite thick, since the silicate brick absorbs water well, and this may impair the strength of the masonry. Put the solution in a thin layer, so the flow is small. It is better to prepare a solution in small volumes.
Another type is cement-lime. To make it, slaked lime should be mixed with water, then passed through a sieve. Sand and cement (1: 3-6) separately prepare the mixture in a dry batch. Then it is filled with lime water. This method improves the plasticity of the solution.
Clay is sometimes added to increase plasticity. Plasticizers are usually added during the preparation of the mortar for facade walls.
Tools for brick laying
When the foundation of the house has already been laid, you can proceed to the construction of walls. To do this, you need materials for the preparation of the solution and construction tools. The latter include:
When working with a trowel, the tool is held parallel to the brick row. At a time, gain a solution with a volume of pear. It is usually enough for a layer of 10 mm thick, under two bricks.When working properly with a trowel, very little mortar is released from under the brick blocks. It is also removed with a trowel.
Ligation of the walls of silicate bricks looks like this
When they put a wall of two rows bricks, you need to remember that the ligation is necessary and between the walls. To solve the problem, you can lay bricks in every second row transversely. So they will connect all the stones. Coincidence in the rows of seams is unacceptable. The second method of dressing - in every fourth row turn several bricks across in a row. Both of the above methods are used interchangeably if the complex masonry consists of three rows.
Brickwork should be reinforced every few rows of bricks
The bricklaying of a silicate brick can be done by a non-professional with the hands of the above simple rules. If you have any questions regarding technology, please contact our experts.
