When choosing a material for building their own home, many are faced with the same question: how to build soundly and economically, but at the same time beautifully and firmly. As a result of a long search for optimal construction technologies, the so-called lightweight masonry was discovered.
Using this type of masonry, it is possible to build walls that are small in thickness and weight, but at the same time have excellent thermal insulation characteristics. The use of lightweight masonry can significantly save indoor space, does not require additional thermal insulation measures, and also significantly reduces the load on the foundation. Consider the main features of lightweight masonry using lithos bricks.
Most often, this type of masonry is used for the construction of low-rise houses and cottages. Lightweight masonry is carried out as follows: two parallel verst walls half a brick thick are built with an inter-wall space, which is filled with heat-insulating material. Lightweight concrete mortar, mineral wool liner blocks or various bulk thermal insulation materials can be used as insulation.
One of the main disadvantages of using bulk materials as a heater is their settling and the formation of internal blown voids, therefore they are considered less effective. Inside, the verst walls are interconnected with the help of mortar internal ties and brick diaphragms, which form closed wells in the masonry. The construction of a lightweight wall, compared to a conventional one, is more labor intensive, but at the same time you get money savings on building materials, as well as a wall with a lower load on the foundation.
As a material for a lightweight wall, a hollow, pressed lithos brick is perfect.
The construction of the walls must be carried out in stages. First, two parallel walls are raised to a height of 1-1.2 meters, then the inter-wall space is filled with lightweight concrete or dry backfill in layers of no more than 15 cm, while carefully compacting each layer.
The construction of walls by this method is possible only on a solid and reliable foundation, as well as in buildings with a small number of storeys (no more than two). The use of dry aggregates or liners as heat insulators of the interwall space allows one to refuse the additional use of water introduced into the wall with a “wet” concrete mortar, which allows one not to wait for the wall to dry, but to immediately begin finishing work. The most surprising thing is that almost any material at hand, which is most popular in this region, but not at all known outside of it, can be used as a filler of voids between the walls. So, cones or moss are often used as a filler in the northern regions, cotton waste is used in Central Asia, etc.
Performing construction work with high-quality litos brand bricks and using lightweight masonry technology allows you to get significant savings on building materials, reduce the total mass of the building without changing the bearing capacity and thermal conductivity of the walls.
We wish you successful construction.
