Concrete block manufacturing - basic technology options

Building

A wide variety of concrete products are widely used in both industrial and private construction. At the same time, one of the main advantages is the fact that the blocks can be made with their own hands - the equipment for the production of concrete blocks is simple, the installation for foam concrete products is somewhat more complicated, but, nevertheless, their cost is also quite democratic. Mastering all the features of the work will not be difficult, the main thing - to comply with the requirements of technology.

In the photo: blocks of concrete, made independently, are almost as good as the factory versions.

The advantages of self-manufacturing blocks

Of course, it is much easier to buy finished products, but the version with independent production has its advantages:

Price	The cost of one product in its manufacture with their own hands is about half lower. This is a particularly important factor when there is a shortage of funds, because you can work with significant savings, although this is a more labor-intensive option.
Quality	You can be sure for sure that only high-quality components were used in manufacturing and all the technology requirements were complied with. Very often unscrupulous manufacturers sell low-quality products, which affects the strength of buildings
Compliance with the requirements	This item is especially relevant if you need blocks of non-standard sizes. You can make your own shape of any size, which immediately solves any questions on the parameters of products
Opportunity to earn	Making blocks yourself can not only provide you with building materials, you can make products for sale. Again, you can invest in your own construction.

Foam concrete blocks are much easier to make than it seems at first glance.

Technology features

Immediately it is worth noting that it is possible to carry out two main types of work: to produce concrete with fillers or foam concrete products. Both technologies have dramatic differences, so we take a closer look at each of the options.

Concrete blocks with filler

Equipment for the production of concrete blocks is simple, you need a concrete mixer, molds and a vibrating table. And in the most extreme case, you can only get away with the form, but this will reduce the quality somewhat.

The process itself is quite simple:

The first step is to prepare the components - sand, cement, filler (it can be crushed stone, slag, expanded clay and much more, it all depends on what component is available in your area).

Note! The correct consistency of the solution - it should form a lump when squeezed in the hand, which breaks upon falling to the ground. This composition is optimal for the production of concrete blocks.

Further, it is necessary to determine the optimal size of the forms, the most popular option is 20x20x40, while it is worth remembering that in the process of work, half elements are often needed, so the 20x20x20 form will also be very relevant. For manufacturing, you can use metal or wood (if wood is used, then from the inside it is best to finish the mold with a tin for perfect smoothness of future products).

The form can be made of anything, the main thing is that the materials are dense

In order to make products easier to get out of the form, all the elements in contact with the concrete are lubricated with special grease or machine oil. (and working out, it is absolutely not important).
The plant for the production of concrete blocks is a vibrating table that seals the mixture.. As noted, it is possible to work without it, but the quality will suffer, so it is better to make the simplest device or do this: take the equipment for a few days.
The instructions for making are quite simple: a solution is prepared, after which the form is filled and compacted in some way.. If the product needs voids, you can use bottles that also need to be lubricated. It is possible to take out blocks in 1-2 days after which drying is carried out for at least 2, and it is better 4 weeks.

Foam concrete products

Technological scheme of production of foam concrete blocks differs from conventional products:

The main components are cement, sand and a special composition to create a foam. In this case, the main importance is to ensure the durability of the foam and its uniform distribution over the structure of products, which is why it is important to use a good installation. The simplest and most effective option today is the use of bar setting, they provide good quality products and cost quite a bit.

Equipment for the production of foam concrete blocks is compact and easy to use - you can master the features of work in a very short time.

The process is quite simple: the required number of components is supplied to the equipment, and within a few minutes the composition is prepared, which can then be poured into molds, and you can fill the formwork and create monolithic structures.

Tip! This option is great for filling cavities - the composition will fill all the voids between the walls and after curing will provide excellent thermal insulation.

This is a great option for your own business - the production of foam concrete blocks has a high return on investment, and you can make a profit after 3 months of normal operation.

Mobile installation allows you to make foam in the right place
