What is concrete-expanded clay stone?

Among the primary components of expanded clay concrete, a type of building material, are:

1. cement;
2. sand;
3. water;
4. expanded clay and various additives.

Baked clay is expanded clay. Granules of expanded clay that are at least 5 mm in size are used in the production of expanded clay concrete.

Because of its low density, this material lets the walls "breathe." Another name for it is a bioblock.

What it looks like in the photo?

The unique feature of expanded clay concrete is its structure, which is made up of expanded clay granules with a cement and quartz sand mixture filling the spaces between them.

This material cannot be mistaken for any other material that contains concrete because lumps of expanded clay can be seen inside the material, between the cement-sand mortar.

Requirements based on GOSTs

There is an existing interstate standard that governs the quality of expanded clay concrete blocks for walls in compliance with GOST 33126-2014. The expanded clay concrete quality must also meet this standard and the following requirements:

1. The surface quality of expanded clay blocks is controlled by GOST 13015.
2. The dimensions of expanded clay concrete blocks (height, length, width) are assigned in relation to the requirements of modular size control according to GOST 28984.
3. The strength of expanded clay blocks is regulated by GOST 18105.
4. The expanded clay concrete from which the blocks are cast must meet the requirements of GOST 25820.
5. The quality of concrete wall stones is regulated by GOST 6133 99.

Additionally, GOST controls material quality (Portland cement, fillers, additives).

Scope of application

Among contemporary builders, expanded clay concrete is a popular material. From there, they construct:

• multi-storey buildings;
• cottages, private houses;
• garages;
• outbuildings.

Both industrial and civil buildings’ load-bearing walls are composed of sections of expanded clay concrete.

Expanded clay stones are frequently used as interior and apartment partitions when building monolithic structures. They can be combined with a range of building materials and metal structures and have precise dimensions.

Types of wall material

As per GOST 25820, the blocks composed of expanded clay concrete exhibit variations based on the material’s density. Block production can use expanded clay concrete material grades ranging from M100 to M300. The density of expanded clay concrete is determined by the granule density, which is threefold: unpexal, porous, and dense.

The most popular material among builders is the unpertured one. It is utilized not only to make building blocks for ceilings and three-story buildings, but also in liquid form to fill in floors.

The most common type of material is porous, which can be used to make the following kinds of blocks:

1. Thermal insulation. Lightweight, low density. Used as material for insulation of the walls of buildings. Not suitable for large loads.
2. Structural-heat-insulating. From them are folded walls and partitions up to 15 m high. It retains heat well.
3. Structural. Blocks from this material are durable. Carrying walls, bridges are built of them.

The priciest type of concrete is dense expanded clay. These blocks are produced using high-end cement brands.

Such expanded clay concrete has a higher thermal conductivity coefficient the denser it is. This substance is applied in vibration-prone environments.

Existence

1. solid sections;
2. with voids inside;
3. wall;
4. septal;
5. facing (with decorative front surface).

Expanded clay concrete blocks are a strong, adaptable, and environmentally friendly building material with superior insulation and lightweight characteristics. They are created by mixing cement with expanded clay aggregates, which results in strong, fire- and moisture-resistant blocks. These blocks are perfect for a variety of construction projects, including residential and commercial buildings, because they are simple to handle and cut. Their ability to insulate effectively against heat and sound helps keep buildings comfortable and energy-efficient. All things considered, expanded clay concrete blocks offer a practical and affordable answer to today’s building requirements.

Production technology

A brick press is required in order to create expanded clay concrete blocks. The completed blocks are heat treated to increase the material’s durability and improve heat retention.

You must carefully follow this order when combining each ingredient:

1. First, cement (1 part) is poured into a container for mixing the components, followed by dry sand (2 parts).
2. After all this is thoroughly mixed, add water (1 part) and continue mixing.
3. Only after this add expanded clay (3 parts). Expanded clay must be wet, otherwise, due to its porosity, it can absorb some of the water from the mixture, and it will become too dry.
4. Water is added to the mass in small portions until all the granules are covered with cement mortar.
5. The resulting mass is poured into molds.

Building mixes that are further enhanced with filler, such as grade M300, are acceptable to use when combining the solution.
