How to make a barbecue from blocks: aerated concrete, concrete, expanded clay concrete


Owners of personal plots strive to equip a recreation area with a barbecue complex. Construction is expensive, so craftsmen equip the place with their own hands using the material left over after repair and construction work. A barbecue made from blocks is the best way to save money.

The barbecue area, equipped on the site, includes a grill, a woodshed and tables

Projects and drawings of barbecues and barbecues made from blocks

Construction of a place for a family vacation begins with choosing a site. The location of the barbecue area should be convenient so that:

  • you could bring food from home;
  • there was a covered canopy to provide shelter during a sudden rain;
  • there was a distance from neighbors so that noisy company would not interfere with rest.


A sketch of the recreation area is drawn on paper, and then measurements are taken and a detailed drawing is made.
A barbecue is built from blocks according to a photo or video instruction. A mini utility unit installed in the recreation area will help you conveniently store firewood, skewers and kitchen utensils for outdoor cooking.


The base is calculated based on the desired dimensions of the firebox

The fireplace exceeds the perimeter of the base by 15-20 cm. Based on the needs and size of the area, determine the perimeter of the barbecue area.


The grill is combined with a grill, cauldron, barbecue and smokehouse

When planning, the distance from the house, neighboring plots and water supply is taken into account. If desired, water and drainage are connected to the grill area and a sink is installed.

Small plots limit the size of the recreation area, so summer residents build a small complex of barbecue, woodshed and table with their own hands. Small structures do not require a chimney.

Subtleties of finishing block masonry

You can refuse interior decoration only in 2 cases: you are decorating the room in a loft or antique style. As a rule, structures built from foam concrete blocks are not left without finishing. Let's find out what you need to consider at this stage.

  • Since we have a porous surface, not all primer compositions will be optimal. Therefore, when choosing a primer, read the instructions. If it says “For cellular concrete”, feel free to buy it.
  • But the choice of plaster is truly impressive. Here you will find pebble, colored, and marbled ones. The main thing is that it is thin-layered and has a polymer-cement base. In open-type gazebos, cladding with decorative stone looks simply magnificent. Usually this is a gazebo with a barbecue.
  • Do you plan to use the structure all year round? Then it should be glazed and well insulated. It is recommended to finish with basement siding and thermal panels on the outside. Another option is cladding with OSB boards, paneling in half-timbered style.

As for the interior decoration, the design will depend on the style you choose, glazing options, and the design of the gazebo itself. Some people line the walls with natural wood, others look towards bamboo or even interior panels. It all depends on your imagination and family budget.

What can you build a grill from?

A stationary barbecue made from blocks in the countryside, made by yourself, is distinguished by its reliable design, strength and durability. Often it is equipped from materials left over from the construction of the house. Concrete blocks are no exception.

The advantages of the material are as follows:

  • high strength;
  • weather resistance;
  • durability;
  • frost resistance;
  • quick and easy installation;
  • low consumption of cement-sand mortar;
  • efficiency.

Attention!
Concrete is a flammable material, so the firebox is made of fireclay bricks or a metal structure. Purchased models of barbecues are not much different, so owners of personal plots try to build an individual structure. Combined structures include not only blocks, but also brick or metal. Modern manufacturers offer a large selection of building blocks:

  1. Foam blocks are made from foaming agent, cement, sand, water and hardener.


    Fine-grained foam block material does not hold nails and screws

  2. Aerated blocks are made from cement, sand, gypsum, metallurgical slag, lime and water.


    Aerated blocks do not shrink, but their disadvantages include high moisture absorption

  3. Cinder block contains ash, slag or shell rock.


    Cinder block is hygroscopic, therefore it is prone to the formation of mold and fungi

Is it possible to assemble a barbecue from expanded clay concrete blocks?

Recently, the construction of barbecues from aerated concrete blocks has become widespread. However, expanded clay concrete is made from foamed and fired clay. The material is light, strong and durable. Experts highlight some advantages of expanded clay concrete:

  • resistant to atmospheric influences and sudden temperature changes, frost-resistant;
  • hygroscopic;
  • environmentally friendly, because it is made from natural materials, without the addition of household chemicals;
  • ease of installation: laying one block is comparable to laying seven bricks;
  • economical in cost;
  • does not support combustion, which means it can be used to build a barbecue;
  • resistant to the formation of fungus and mold.

Do I need to line the walls?

It is recommended to make external cladding of walls from blocks, as they are not resistant to moisture. If they are without a protective coating, then after 2-3 years the walls will begin to crack and the blocks will begin to crumble. It is advisable to begin finishing work no earlier than a month after completion of construction, because the blocks shrink after some time.

These materials are usually used for cladding blocks:

  • Various decorative plasters (marble, stone, relief, multi-colored). Only thin-layer ones with a polymer-cement filler are suitable.
  • Natural or artificial stones with high levels of heat and sound insulation will help make a fairy-tale house out of a gazebo.
  • Composite panels. Their advantages are that they are durable, quite easy to install, durable, moisture-resistant and come in different colors.
  • Siding. It is attached to the top of the sheathing. It is advisable to insulate the walls in advance. This material is not afraid of moisture, inexpensive, and easy to replace.
  • Facing tiles. Recommended for finishing closed buildings and open-type pergolas. Under no circumstances should siding be attached with screws or glue. A vapor barrier should be laid underneath it. This material is characterized by a wide selection of paint palettes, as well as ease of installation and low cost.

Where is it better to build a barbecue area and grill?

Before arranging a place to relax, experts advise studying the recommendations for constructing a barbecue area from blocks with your own hands. When planning, take into account the location:

  • to the fence from 1 m;
  • to bushes or trees from 3 m;
  • 3-5 m to a residential building.

Conclusion

We hope that after reading, your desire to make a barbecue yourself has only strengthened, even if you decide to make foam blocks with your own hands. Your dream has become a little closer to you, because after a short hassle, you and your loved ones will be able to enjoy delicious dishes prepared in the fresh air.

Plus, you will have pride in the fact that you did it all yourself, without involving outsiders. In the future, you can continue this tradition and build small buildings on your site, because a wall made of foam blocks with your own hands, as well as a partition made of foam blocks with your own hands, will not require you to spend a lot of money, especially since you will already have experience in this in fact.

In the video presented in this article you will find additional information on this topic.

What tools and materials will be needed

After planning the site and creating a project, they begin to prepare the necessary tools and materials. To build a barbecue from blocks and bricks with your own hands you will need:

  • blocks;
  • fire brick;
  • cement, sand, clay, lime for mortar;
  • boards or plywood for arranging formwork;
  • fittings made of metal or fiber optics;
  • grate, door and other oven accessories;
  • shovel;
  • level;
  • screwdriver and screws;
  • decorative material.

Foundation

Let's start building the barbecue. First we do the foundation. It must be level and able to withstand the load from the grill structure. The best option is a reinforced concrete slab 1500 x 1000 mm, height 150 mm.

We are building such a slab. We remove the fertile layer of soil and make a sand cushion 200 mm thick, leveling and compacting it. We lay a waterproofing material on top of it, which will protect the slab from getting wet. We subsequently use the same material to protect the vertical part of the slab.

We install the reinforcing mesh on certain fasteners, for example, plastic ones, so that after pouring the concrete, the mesh is inside it and the metal does not have the opportunity to corrode. We install plank formwork along the perimeter of the base, and then pour concrete grades B25, M300.

How to make a prefabricated grill from concrete blocks

The construction of a barbecue oven from blocks with your own hands begins with clearing the site. Debris and grass are removed and the turf is removed.

Step-by-step instructions for carrying out the work:

  1. Markings are made on the cleaned, prepared area. Pegs are installed around the perimeter and string is pulled. According to the markings, remove the top layer of soil, deepening it by 20 cm.


    Gravel and sand 5-10 cm high are added to the bottom

  2. Formwork is installed around the perimeter. At the corners and in the center of the sides, stakes are driven in from the outside and the structure is secured using self-tapping screws with a screwdriver. A mesh of reinforcement is laid at the bottom. Filled with concrete.


    Concrete mortar is made in the proportions of one part cement to 3-4 parts sand

  3. According to the drawings, the first row of blocks is laid out. Cement-sand mortar is made in a ratio of 1:3.


    To ensure that the next tier is securely fixed, a piece of reinforcement is inserted into some cells of the block

  4. After laying the second row, they begin to arrange the formwork. Crushed stone is added to the solution of cement and sand. This will make the structure more dense. The concrete is left to mature for 10-14 days, watered daily.


    A metal corner is placed at the base to prevent concrete from splitting when the firebox heats up.

  5. After the concrete has hardened, the formwork is dismantled. Install the grate.


    Pieces of metal reinforcement are welded to the corner or a ready-made grate is installed

  6. The firebox is made of refractory bricks. For coupling, prepare a clay-sand mixture or buy ready-made concrete for braziers. A metal corner is used to make an edging around the brick firebox.


    The solution is prepared from clay, sand and lime in a ratio of 1:3:0.25

  7. To make a DIY block grill look attractive, it is decorated with plaster. The structure is painted in a suitable color.


    In addition to plaster, stone or porcelain tiles are used for decoration.

Question with masonry composition

It is very important to choose the right masonry composition for a planned project. The easiest way is to purchase a ready-made solution. But its characteristics may not correspond to those reflected on the packaging.

It is better to find the correct proportions of clay and sand through your own efforts. The formed composition, when dried in the sun, should not crack and retain its strength.

Perhaps your experiments may take longer. But, when you independently achieve the required working mixture conditions, in the future you will spend much less time searching for optimal proportions and will be able to prepare high-quality masonry mortar.

How to make a barbecue complex from aerated concrete

Do-it-yourself construction of a barbecue from a gas silicate block is gaining increasing popularity. The material allows you to construct structures of various shapes and is easy to saw without chipping. The construction of a barbecue complex with your own hands is carried out in several stages.

Preparing the rough foundation

Markings are made in the prepared area according to the drawings. The top layer of earth is removed along the perimeter to a depth of 20 cm. Lay aerated concrete blocks. Check the level. Gas blocks are fixed using a cement-sand mixture made in a ratio of 1:4.


Vertical seams are secured using thin-layer adhesive

Laying a finished base of aerated concrete

Gas blocks are laid on top of the rough layer using thin-seam glue. Blocks 15 cm thick are used for the base.


The evenness of the masonry on the horizontal surface of the blocks is checked using a building level

Laying gas blocks

Following the drawing, they lay out the woodshed, firebox and chimney. In order for the gas blocks to be reliably connected into a single structure, a number of rules are followed when laying the blocks:

  • the width of the trowel is equal to the width of the gas block;
  • Before applying the glue, the surface of the gas block is cleaned with a spatula and a brush;
  • glue is applied to each joint;

Attention! If the glue sticks out during laying, do not lubricate it, but wait until it dries completely, then cut it off with a knife.

Construction of a firewood shed

Three rows of gas blocks are laid sequentially on the prepared base, following the drawing. Blocks 10 cm thick are used for the back wall, and 15 cm thick for the partitions.


Each block is checked with a level so that there is no distortion of the structure in the future.

Installation of barbecue firebox

To construct the firebox, a horizontal base is created from gas blocks 10 cm thick. Blocks 15 cm wide continue to be laid vertically on top of the base. The back wall is laid out from blocks 10 cm thick.


The last row is processed with a sanding board to obtain a completely smooth surface.

So that in the barbecue you can burn not only charcoal, but also firewood, the firebox is reinforced with heat-resistant brick from the inside. Install the grill grate.

Facing and assembling the barbecue

A metal corner is installed on the firebox. A stainless steel exhaust hood is attached to it. To make the structure have an attractive appearance, it is decorated with facing materials.


The structure is decorated using facing bricks, wild stone or decorative plaster

Why foam block?

In fact, it is quite possible to build a gazebo with your own hands from scrap materials. To some, cellular concrete blocks may seem like an unsuitable option. Everything is exactly the opposite - and now you will understand why.

The main reason for its popularity is the fairly large format of the material. It allows you to build masonry many times faster than brick. The reinforced concrete argument was also the price of the material. The most affordable brick is sold for 4,500 rubles/cubic meter. m., while blocks measuring 50 x 40 x 40 cm will cost you 2500-2800 rubles for the same volume.

But that's not all. One cubic meter of aerated concrete weighs about 3 times less than bricks of the same volume. Consequently, the load on the foundation is very modest.

“But brick is much stronger than foam blocks!” Skeptics will be indignant. Really stronger. However, for a home gazebo this is completely unimportant - it will “withstand” even the noisiest events!

Advantages of foam blocks

Foam concrete is a relatively new material on the construction market, but has already gained quite wide popularity. For the construction of a gazebo, foam block is good, first of all, for its low price and ease of use. The price of a cubic meter of foam block with delivery, regardless of its size, will average 3,000 rubles. The cost of a cube of the cheapest brick is 4,000 rubles.

Foam concrete blocks pros and cons

The material is very light, its specific weight is almost three times lighter than the same brick. This allows you to greatly speed up installation time, while doing it yourself. Light weight reduces the pressure on the foundation, and this, in turn, reduces the cost of its construction.

Foam blocks are easily sawed with a special hacksaw, which allows you to create non-standard shapes of the structure. Of course, like any building material, foam concrete has its drawbacks. It does not have the same strength as brick, especially low-density brands of blocks. Capable of absorbing moisture, which forces the use of additional protective measures. Any finishing will have to be applied to it, since the appearance of the foam blocks does not agree with our ideas about the lightness and elegance of a summer gazebo in the garden.

Foam concrete has the bad property of easily chipping, especially on the edges. Lifting work with it must be carried out carefully and carefully.

The standard length of all blocks is 600 mm, the width can be in the range of 250 - 400 mm, and the thickness - from 75 to 200 mm. Blocks are also available in lengths of 300 mm.

The laying of foam blocks is carried out using a special assembly adhesive, which is widely available.

Useful tips

As promised, at the end of the publication we want to give you some really useful tips. Be sure to use them when you build a gazebo from foam concrete.

  • Are you thinking about additional lighting for your summer building? When the wiring is laid in grooves, it must be plastered. And the cable itself must be laid in a steel sleeve.
  • Openwork grilles look great in a gazebo made of foam blocks. Just don't forget to treat them with an antiseptic solution.
  • To organize concrete drainage, you install concrete structures up to 25 cm deep. Try to allow moisture to flow onto the lawn.

Congratulations - the gazebo made from practical and affordable foam blocks is ready. You can admire the work done and be proud of yourself. And also invite your family and friends to a small housewarming party!
