How to make lightweight aggregate concrete blocks with your own hands for building a private house: Review + Video

Developers began to use claydite concrete with pleasure, as they made sure of the manufacturability, reliability and practicality of this material. This article will tell you about what claydite-concrete blocks are and how to make them yourself, what are their features and advantages over other building materials.

Learn about the production technology, how it is possible to make claydite-concrete blocks with your own hands, is this process worth the time and effort.

Advantages of erecting buildings with expanded clay concrete

Claydite concrete is lightweight, which allows you to create durable housing of a fairly presentable look, even on a small foundation ..

.

Claydite concrete - the only one with the most promising modern materials for construction. Its properties in terms of the speed of construction of various objects and the economy of use significantly exceed the quality of other materials.

Expanded clay concrete structures are made exclusively from natural components, and for this reason they do not emit toxic substances into the environment. If you believe the reviews of those who built a house from expanded clay concrete blocks, they claim that very comfortable climatic conditions for living are established in the room.

Production of expanded clay concrete blocks

Expanded clay concrete has unique properties determined by the peculiarity of their manufacture. Expanded clay is taken as a basis - an environmentally friendly material.

It has pores resembling a sponge in structure, in which there is specially fired clay, which acquires the texture of a solidified foam.

As a result, such material turns out to be very light and durable. Cement is used as a binding component.

Strength and ability to retain heat depends on the correct proportions of the mixture. The more granules in the mixture, the more brittle the block becomes, but at the same time, the warmer, and vice versa.

Varieties of expanded clay concrete blocks

Claydite concrete structures, according to their own physical and technological data and purpose, are divided into:

1. thermal insulation;
2. structural and thermal insulation;
3. structural.

The density of heat-insulating expanded clay blocks is the lowest. This type of expanded clay is made in a special way that promotes the formation of large pores. The density of such granules is 150-200 kg / m3.

Structural expanded clay resembles natural stone, which is why the walls of a house made of such material will be extremely dense. A significant advantage of expanded clay concrete over other building materials is the price.

The pace of installation of walls made of expanded clay concrete is 4 times faster when compared with brick buildings.In addition, when building houses from this material, 2 times less mortar is used, again when compared with brick.

The desire to have a private house pushes people to search for cheap materials for construction. Expanded clay concrete blocks are just the material that is increasingly popular with developers.

The main feature of expanded clay concrete is that in addition to the low cost on the market, it can be made by hand. We propose to consider the main nuances and tricks, as well as the composition of expanded clay concrete blocks according to GOST.

What do you need to start?

The manufacturing process is simple, the main thing is to adhere to the proportional ratio of components - 1: 3: 8. Water is added at the rate of 200 liters per 1 m3.

Materials

1. Cement.

   The popular brand of cement M400 must be taken at the rate of 1/10 of the volume of blocks.

2. Expanded clay. Density from 350 to 500 kg / m³, fraction - 5 - 20 mm. 8 parts are added to the solution.
3. Sand.

   The best option is coarse or medium-grained sand from the river without impurities. You can take quarry sand pre-sieved and washed. For the solution you need 2 parts.

4. Water. The required amount according to the technology is 215-230 l / m³.

   Excess and lack of water leads to the formation of cracks and loss of density of the material.

5. Additives . Experts advise adding various components to the solution to increase frost resistance, moisture resistance and strength of expanded clay concrete. Do I need to add plasticizers to the solution? The main additives are clay, wood ash, laundry powder, liquid soap, dishwashing detergent in the amount of 1% of the amount of cement.

Tools

Manual Vibration Pressing Machine

You can buy it in shops where they sell everything for construction.

The approximate cost is 7 - 10 thousand rubles. Can also be ordered from manufacturers. The design already has special molds for casting blocks. Also, the machine can be made with your own hands from an old engine and a metal tabletop.

Concrete mixer

Recommended capacity of concrete mixer 130 ml, approximate price 9 - 12 thousand rubles.

In one working cycle, the machine produces 1 - 4 blocks. And if you assemble a team of several workers, the number can increase by about 2 times. Blocks can be made without equipment, the main thing is to pick up a capacious mixing container and pour into molds.

The forms themselves for expanded clay concrete blocks can be made of metal, plastic, wood (fastened with metal corners, and sheathed inside with them).

Some craftsmen use plastic bottles filled with water to form voids in the blocks.

When mixing the mortar, the exact amount of water is taken first. Sand, cement and expanded clay, sand are mixed, and then liquid substances (water, plasticizers) are introduced. The mixture should look like softened plasticine.

Drying of expanded clay concrete

The final stage of making blocks from expanded clay concrete is drying the finished product.

Then the blocks are stacked on pallets in a row of 3-4 pcs. The finished blocks should not be exposed to sunlight and rain; it is better to keep them under a canopy. They are allowed to work in 1-1.

5 weeks after manufacture.

The best option is to dry for a month. Before laying, the blocks are cleaned by roughness and irregularities.

The cost price of expanded clay concrete blocks with your own hands

According to some estimates, the approximate price of expanded clay concrete blocks will be about 20 rubles. For comparison, the price of finished products is about 80 rubles.

Savings, as they say on the face.
