How to make foam concrete yourself

You need to prepare specialized equipment and research manufacturing technology in order to produce a high-quality material. It accommodates the following subtleties:

1. Only pure cement with a grade of at least 400 can be used as raw material for the manufacture of foam blocks at home.
2. Foam is added only after thorough mixing of the main components.
3. To check the quality of the final product, you need to collect a small amount of the mixture in a bucket and turn it over: high-quality foam will not flow out.
4. In a semi-hardened state, the concrete is removed from the molds and divided into small blocks. The optimal period after which the material is removed is 24 hours. After cutting, the blocks are dried on a pallet for 15 hours at a temperature above 5°C.

You can use the following tools and techniques to create foam concrete by hand:

1. Autoclaved.
2. Simple.
3. Non-autoclaved.
4. Using a concrete mixer and foam generator.

In most cases, home craftsmen create the material without using an oven. And although the production technology itself may seem quite simple and accessible, if some rules are not followed, the final product will be of low quality and will not meet the stated performance requirements.

The proportions of the components should be accurately calculated before beginning production, and the best time to mix, dry, and age the molds should be selected. Foam concrete will be trustworthy and long-lasting if these guidelines are followed.

What you need to have for production

Several supplies and tools need to be ready before production begins; You can use your hands to make foam concrete by using:

1. Concrete mixer. Its volume is determined by the needs of the client. A 300 l unit is enough to implement private construction projects.
2. Medium-fraction river sand, which does not contain any impurities.
3. Cement mixture grade M400-M500. It is prohibited to replace it with any other components.
4. Steam generator for foam concrete. Production can be started without this equipment, but its presence guarantees increased strength and reliability of the final product.
5. Water.
6. Containers for pouring the finished mixture. Hardware stores offer ready-made forms for foam blocks and gas blocks.
7. Foaming agent.

In certain circumstances, additional components are also utilized. adding a coloring additive that lets you color material for rooms without having to finish. In order to strengthen foam concrete’s resistance to adverse conditions like moisture and low temperatures, a hardener can also be added to the mixture.

Independent production method

When mixing foam concrete by hand at home, you need to figure out how big the container the finished mixture will go into. You should calculate the amount of each component based on the results. For example, 100 liters of water and 200 kg of cement mixture with sifted sand are needed for every 0.5 m³.

Sand and cement are added to the concrete mixer first. Then, 500 liters of foam are produced per 1 m³ using a specialized tool and a foam concentrate. After diluting the cement mixture with water, foam is added.

A pumping element is a feature of many foam systems that facilitates the rapid and effective pumping of the mixture into the drum.

The components need to be well combined after being added to the container. Various amounts of foam are added to the mixture to alter the density. After being poured into the mold, the solution is dried. After that, the dry blocks are removed and given a full day to dry.

Hardware stores sell foam generators, or they can be made by hand. One kilogram of rosin, sixty grams of wood glue, and one hundred grams of caustic soda are needed for this. After combining, heating, and mixing, all ingredients are smoothed out. Water is added to the solution prior to production.

It is possible to create the block’s mold by hand using homemade materials. At this point, more accuracy and technological adherence are needed. If not, the blocks’ geometry will be incorrect. The solution needs to be covered with polyethylene film to stop it from leaking out. The next one can be poured after the previous one has been removed.

Cost price

Handmade goods are far less expensive than store-bought blocks. In order to prepare a cubic meter of high-quality material that matches the D600 brand, you should be aware of the following ingredients: The typical recipe looks like this:

1. 200-250 kg of sand-cement mixture.
2. 1.5 l of foam former.
3. Water. Can be used from a centralized water supply. The main thing is to correctly calculate the proportions of foam concrete and water.

The cost of the electricity that the equipment will use should also be considered. Depending on the area in which the mini-production is situated, they may change.

Thus, the cost of electricity in Moscow is higher than in other parts of the city or in remote areas. The majority of the expenses are incurred in buying cement. Simultaneously, the kind of equipment utilized dictates the amount of money invested.

Stages of work

If you want to learn how to make foam concrete at home, you must thoroughly research the technology used to create foam blocks and determine the best mixture. Following this, you can carefully follow the instructions and carry out the necessary actions step by step.

Foaming agent solution

Cement mortar must be ready in order to use foam concrete technology. The same process as for regular concrete is used to create it. It is advised to use M400 or M500-branded products when making a cement mixture.

Verifying that the sand is dry and free of extraneous additives or impurities is crucial. To dilute the components, plain water from the centralized water supply system is utilized.

The completed solution is enhanced with foam. Every hardware store sells foam generators, or they can be made with homemade devices.

Pouring the solution into molds

Pouring the prepared consistency into the prepared molds is the next step. The containers are lubricated with a unique solution prior to this operation. Two techniques are known to builders for creating foam blocks by hand:

1. Casting.
2. Cutting.

Filling in the blanks with the solution is the first technology. After it solidifies, you can take it out of the mold and give it a few more hours to solidify completely. There are several drawbacks to using this method. First of all, there’s a chance that the metal will be harmed, and the blocks may distort during removal.

Unevenly shaped structures are not only difficult to install, but they are also weak and of low quality. The cutting approach, however, is more costly because specific equipment must be purchased.

Cutting technology

The completed slab is divided into multiple sections during the cutting process used to produce foam concrete blocks. The raw material reaches its ideal strength in 6 to 9 hours and can be taken out of the formwork. After that, a crossbeam transports the ready array to the cutting apparatus, where the expert starts cutting.

Because the allowed deviation is limited to 1 mm, this technique has the highest accuracy. The cutting complex has twisted strings that cut the material and a unique screw for taking off the top. The expert adjusts the cutting strings’ position to produce various block sizes. A cycle takes five to seven minutes.

The container containing the blocks is put somewhere to dry after the event. Depending on how well it dries, the foam block is taken off the pallet and placed in storage after 12 to 24 hours.

1. The geometry of the blocks is even and correct.
2. The edges have no deviations.
3. Any chips and irregularities are excluded.

Among the drawbacks are:

1. Additional costs for the purchase of equipment.
2. If the concrete does not harden, it will be destroyed during cutting.

Recommendations of specialists

Experts advise following specific guidelines and standards so that you can produce high-quality content free from mistakes and deviations:

1. For the manufacture of forms for future foam blocks, it is recommended to use plywood with a laminated coating or durable metal sheets.
2. Before placing the solution in the workpiece, it should be treated with the solution, and the structure itself should be covered with polyethylene film.
3. Drying is carried out in the temperature range of +50 … + 60 ° C for 48 hours.
4. The material can be removed from the mold only after it has completely dried.
5. The finished block is kept on pallets for several hours. Only after this it can be used for its intended purpose.
6. You can start plastering the walls only 3-4 months after laying, since the blocks shrink.
7. Before starting finishing work, you should clean the material from dirt and dust, and also carefully prepare the surface for applying the layer.

Home fabrication of blocks

If you are proficient in basic production techniques and have the necessary tools and supplies ready, you can set up a small factory at home to produce foam concrete. In addition to saving money on building material purchases, this solution will start a small business.

Crafting foam concrete at home is a satisfying project that blends imagination and usefulness.
