Features of construction from expanded clay concrete blocks
Probably there is not a single family that does not dream of a warm and a cozy home. Very often, such dreams are broken about the realities of life, which are associated with the material side of the issue, and in this case, you should pay attention to houses made of expanded clay concrete blocks. In the building materials market, products made of such lightweight concrete have not lost their popularity and have remained at their peak for several decades due to the favorable cost-quality ratio.
Let's consider all the parameters of the material in more detail, as well as different work technologies. Let's figure out what are the features of building a house from expanded clay concrete blocks, so that such a building warms you, and your children, and even grandchildren with warmth.
Products from lightweight concrete, in which the main filler is clay fired pellets, is incredibly popular in the construction of low-rise private houses, and also during the construction of country houses and auxiliary types of buildings. Expanded clay is environmentally friendly, lightweight and porous, and at the same time very durable.
When binding the pellets with a cement solution, products are obtained that have many positive aspects:
The advantages that do not affect the quality of work, but improve the mood when buying and during the production process of construction work, include the following:
After studying the merits, it may seem that a house made of expanded clay concrete blocks is ideal, and the reviews of the owners largely confirm this opinion. But when choosing a building material, you should not close your eyes to the minuses, which include:
In this regard, house projects from such blocks contain requirements for the insulation of the box.
By studying the advantages and disadvantages, you can properly prepare for construction activities.
One of the preparatory steps of construction is the calculation stage.
After the development and approval of the project, it is required to calculate the need for materials. You can determine the required amount of building material yourself. Take, for example, a one-story house made of blocks with a size of 15 * 10 meters and a ceiling height of 3 meters. Calculations can be made in two ways - by volume or by area.
When calculating the required number of elements according to the first option, you need to act according to the following algorithm:
- Determine the total wall area, in our case it is (10 + 10 + 15 + 15 ) * 3 = 150 m 2 .
- Calculate the number of units required per square meter. For element with dimensions 0.4 * 0. 2 * 0. 2 meters is 12.
5 pieces (1/0. 4 * 0. 2 = 12. 5).
- Multiply the total wall area of the walls and the number per square meter - you get the required number of product units (150 * 12.
5 = 1875 pieces).
The second option for calculations will be similar to the first, but when making calculations, they operate not with indicators of areas, but with dimensions of masonry volumes in one unit of production. It should be emphasized that the design process does not take into account door and window openings. This was done deliberately in order to take into account the loss of building material during the work.
When you understand the parameters, advantages and disadvantages of products, studying the methods of calculating the need for building material and making its purchase, you can start building type work.
To build a solid and at the same time durable house from blocks of expanded clay concrete with your own hands, you need to adhere to time-tested technologies. The general algorithm of the construction process is as follows:
Let's dwell on each item in more detail.
When choosing a type of foundation, first of all, you need to focus on the structure and soil composition, as well as the level of groundwater. Of the incredible variety of foundations for building from lightweight concrete, only 3 types are suitable:
When analyzing the land at the construction site, you will be able to determine which of the bases will be preferable. The slab base is justified on prone to movement, unstable soils. Due to its huge area and increased strength, it can compensate for bending loads and prevent cracking of the material during soil shear. But there is a nuance that you need to know about - the slab base is laborious in the arrangement.
A pile-type foundation has a large number of advantages when building on soils that are prone to frost heaving.
It is also indispensable in the case when you need to build a building on a site with a slope. But the pile foundation unevenly distributes the loads that appear when the soil moves. For this reason, when choosing a screw structure for a house made of lightweight concrete, it is required to weigh the pros and cons well. Ideal for low groundwater occurrences is a strip-type foundation.
It has many advantages over other types of foundations for building a house from expanded clay concrete blocks:
Work on filling the tape-type base according to the following algorithm:
- First, you need to plan the surface area - uproot shrubs and trees, and remove small vegetation manually or through chemicals.
- Mark the base using rope and pegs.
- Dig a trench to a depth that is greater than the frost penetration level.
Trim the bottom and sides of the trench.
- Prepare and install the formwork - you can use board trims or use plywood panels for it.
- Fill in the crushed stone-sand mixture into the trench, and then tamp.
- Assemble a reinforcing type frame - you need to connect metal rods and you can do everything by welding or knitting wire.
- Prepare a concrete solution according to the recipe - use a concrete solution for work with a grade of at least M400.
- Pour the prepared compound into the trench - tamp the mortar thoroughly to remove air bubbles.
- Smooth the surface, cover with polyethylene in order to keep moisture.
- After the end of the curing process, the formwork must be removed.
- Waterproof the base.
Now about the walls.
Work on the construction of the walls of a two-storey house from blocks of expanded clay concrete type in the same way as a country house from expanded clay concrete blocks is carried out according to the general algorithm:
When the work is over, you can start installing the roof.
The roof, as well as the foundation, is a guarantee that the structure will be durable. Before proceeding with the installation of the roof, think over the design, select the desired floor material. There is no need to save money when choosing a roofing material.
It is important that it is strong, durable, resistant to the influence of natural factors and environmentally friendly. For roofing installation, you need to prepare the following materials:
Guided by the documentation, it is required to assemble the frame and fix the roofing material.
Such buildings need insulation. Developers often have a question of how to insulate a house from blocks of expanded clay concrete type. In order to maintain a comfortable microclimate, thermal insulation must be installed both outside and inside. This holistic approach to thermal insulation will allow you to reduce costs in order to maintain a favorable temperature level.
Features of insulation outside. For external insulation, it is required to choose the ideal thermal insulator. The most popular heaters include:
- Polyfoam - it is characterized by low cost, ease of installation, ease of finishing. Cons - incombustibility and damage by rodents.
- Mineral wool - differs in affordable cost, increased properties of thermal insulation.
When laying outside the building, a prerequisite is the use of waterproofing.
- Cladding panels - are distinguished by their high cost and high level of installation costs, and the installation technology ensures the effectiveness of thermal insulation.
Any of the options that are proposed have the right to life. The choice will depend on finances.
How much does it cost to build houses from lightweight aggregate concrete blocks? The estimated construction price can be calculated by summing the following cost items:
Taking into account the current walls, you can get an approximate cost and plan the amount of upcoming expenses.
