The construction of country houses, cottages and other low buildings does not cease to be relevant, and its pace is only growing every year. In this regard, materials such as foundation building blocks (FBS) are in demand.
They are usually used for the construction of strip foundations, basement floors of buildings and basements. Today FBSs are in demand products in the construction market, and therefore their production can be an excellent business, requiring very real investments.
The main thing in implementing this entrepreneurial idea is not the place or even the experts (it is not so difficult to train them), but the equipment for the production of foundation blocks. It is it that makes up the main cost item and plays a crucial role in the manufacture of quality products.
Foundation blocks and their types
Such blocks are made of heavy concrete, less often - on the basis of silicate or expanded clay concrete. The density of this building material is from 1800 kg per cubic meter or more, and at the ends there are special grooves for pouring cement mortar. They are currently being released in three main forms:
- Solid - the material most common for the construction of basements and socles. It transfers the load to the base well.
- Hollow - have good heat and sound insulation properties. Their smaller mass allows to reduce the cost of transportation and installation of blocks.
- Solid with cutouts - convenient for communication. Cables and pipes easily pass through special cutouts in blocks.
Not only designs differ, but also the sizes of the foundation blocks. Their height is usually 30 or 60 cm, length - 90, 120, etc., width - 30, 40, 50, etc. The exact dimensions are indicated when marking products.
Block Production Technology
The manufacture of this building material is carried out by vibropressing. Thanks to this technology, it is possible to obtain blocks with the best operational properties. However, the entire production process includes, in addition to the above, a few more steps:
- solution preparation;
- laying in the metal form of mortar and reinforcement;
- already mentioned vibrocompression;
- extraction from the finished block form.
At every step, certain equipment for the production of foundation blocks is used. It has different performance, types of forms are also different, and allows you to receive products with additional elements (cutouts, voids, etc.).
Equipment for blocks
In order to automate the process as much as possible and thereby achieve high performance, the following equipment for the production of foundation blocks is used:
- FBS manufacturing facility;
- disassembling forms;
- concrete mixer (reduces manual labor).
It is very important to make sure that all of these items comply with safety criteria and building codes. For this, equipment should be purchased from large, trusted suppliers.
Installation Work: Steps
The basic element is a machine for the production of foundation blocks. He makes FBS ground formation (of different sizes and types). The installation works as follows:
- the solution is loaded into the form;
- the process of vibration begins, which lasts from 25 minutes to an hour;
- by electric lift the form rises up;
- the block remains on the surface;
- the process is repeated after the installation is moved.
Usually, an additional form for the production of foundation blocks is attached to the main installation. It is universal.
Improving the quality of building blocks
In order to improve the physical and functional characteristics of the foundation blocks, various plasticizers are added to the concrete mortar.
They allow you to get products of higher strength and reliability, as well as extend the life of finished products.
Thanks to additional elements, the resistance of blocks to mechanical influences increases, frost resistance and moisture resistance of the material are improved.
It tolerates temperature differences better, which means the building structure will turn out to be more reliable.
It should be noted that the foundation blocks do not lose their performance over time. This allows you to use them in construction repeatedly.
Conclusion
Manufacturing FBS blocks is neither difficult nor costly. The main expense item includes equipment for the production of foundation blocks (machine, molds and concrete mixer) and the hiring of personnel. Fortunately, only two people can service the installation, and it’s not difficult to learn the technology of manufacturing blocks (special skills are not required).
At the same time, this business is today in high demand and, accordingly, quite profitable. It is enough to carefully study the process of organizing production and take a niche in time if it has not yet been captured by someone more entrepreneurial.
