What are aerated concrete blocks? What is the difference between aerated blocks and aerated blocks

Aerated brick is a new type of lightweight wall brick. Generally, foam concrete is cut into small pieces, which has higher requirements for process and strength, and some of them also need steam curing, so the cost is higher. Our company has additives for aerated bricks, which can shorten the curing time and improve the strength.

Aerated concrete blocks are solid bricks. Aerated concrete blocks, this one is solid inside. So it's a solid brick.

Hollow devices have a hollow interior. Aerated bricks are made by firing clay. "Autoclaved aerated concrete block", referred to as aerated brick, is an aerated concrete block produced by high-temperature autoclaving equipment technology.

"aerated brick" can be understood as a simplified or generic name. It should cover a larger range of products, i.e., bricks produced by other processes including autoclaving.

Aerated mixing your Nanning diagram block is a stone that can float on the surface of the water - some people call it pumice! The pores in the middle make this material very light—also known as lightweight bricks, lightweight walls; It also makes this material able to block sound - also known as soundproof bricks, soundproof bricks; Because the material contains a lot of air - also known as aerated bricks, aerated blocks; At the same time, this material has good thermal insulation performance - also known as thermal insulation bricks, energy-saving bricks; The most important thing is that it is made of concrete and has high strength, so its technical name is - autoclaved aerated concrete block (there is a national standard).

Based on its good characteristics, aerated concrete, which is widely used as a wall material for buildings, is a porous silicate product made of siliceous materials (sand, fly ash and silica-containing tailings, etc.) and calcareous materials (lime, cement) as the main raw materials, mixed with gassing agent (aluminum powder), stirred with water, formed by chemical reaction to form pores, and made by pouring molding, pre-nurture cutting, autoclaving curing and other processes.

Aerated concrete has a high resource utilization rate (1m3 raw material can produce 5m3 of products), which not only contributes to the human living environment, but also provides a broad profit margin for its producers.

Aerated concrete has low energy consumption (including production energy consumption, transportation energy consumption and use energy consumption), and can make a large use of industrial wastes such as fly ash, tailings sand and desulfurization gypsum, which is in line with the development of circular economy strategy.

Aerated block and aerated block are a kind of thing, aerated block is a relatively simple statement, the full name is aerated concrete block.

Aerated concrete block is a new type of building material that is lightweight and porous, thermal insulation, good fire performance, nailable, sawable, planable and has certain seismic resistance. Already in the early thirties, such products began to be produced in China and were widely used. It is an excellent new building material, and has the advantages of environmental protection.

Product advantages: light weight, thermal insulation, high strength, seismic resistance, processability, high temperature resistance, sound insulation, mechanization.

Good. Okay.

Hello, concrete aerated hidden block lime and cement as raw materials, after ingredient pouring, gas expansion, cutting and maintenance and other processes made of slippery spring light thermal insulation new building materials, the process is divided into raw material transportation, lifting and grinding, measuring, pouring, curing stove and other processes. It is characterized by light bulk density, high thermal insulation performance, noise insulation, and processability.

1. The aerated mixed spring concrete block is suitable for all kinds of inner and outer filling walls above the ground of Liangsun buildings and the inner filling walls below the ground, except for the walls with special requirements. Aerated concrete blocks should not be built directly on the floor or ground. For the root of the wall that is often subjected to alternating dry and wet, it is advisable to pour a C20 plain concrete wall mat with a width of the same wall thickness and a height of not less than; For other walls, autoclaved lime sand bricks should be used to build masonry at its root, with a height of not less than 0.

2m wall mat. 2. These parts shall not be used for aerated concrete blocks: the following parts of the building (except for the basement indoor filling wall); Long-term immersion in water or frequent alternating wet and dry areas; Environments subject to chemical attack, such as strong acids, alkalis, or high concentrations of carbon dioxide; The surface of masonry is often in a high temperature environment above 80; Roof parapet.

Sand aerated concrete block is different from aerated block concrete masonry! Hello, I am glad to answer your <> pro 1The appearance color of sand aerated concrete blocks is relatively white, and if it is river sand, some of them have a light yellow.

Touching the block with your hands is surrounded by water chestnuts, and there is a feeling of thorns. 2.The appearance of fly ash aerated concrete blocks is darker, and some have a navy blue color.

Touch the corners of the block with your hands, and the water chestnut is softer than the sand and gas. 3.Because there are more hard substances such as quartz stone and mica in the sand, the appearance strength of the sand aerated block is relatively easy to carry.

Fly ash is just the opposite, the better the strength, the easier it is to collapse the edge of the surrounding water chestnut. Hope mine can help you <>

Do you have any other questions?

Aerated concrete block is a solid block made of cement, slag, sand, lime, etc. as the main raw materials, adding gassing agent, stirring and molding, autoclaving and curing.

Aerated concrete blocks are divided into seven strength grades according to their compressive strength: A1, A2, and seven strength grades.

Aerated concrete blocks are divided into six density levels: B03, B04, B05, B06, B07 and B08 according to their density.

Aerated concrete blocks are divided into excellent products, first-class products and qualified products according to the dimensional deviation and appearance quality, density and compressive strength.

1. The bulk density is different.

The bulk density grade of concrete aerated block B05 is 500, and the bulk density grade of concrete aerated block B06 is 600.

2. The quality is different.

B05 requires the bulk density of the block per cubic meter to be less than 525 kg (qualified product) or less than 500 kg (excellent product) B05 block has two strength grades, which are excellent products, qualified products, and excellent products of B05 level blocks.

B06 requires the bulk density of blocks per cubic meter to be less than 625 kg (qualified products) or less than 600 kg (excellent products), which is a qualified product of B06 level blocks.

Yes. Because the aerated block has a large water absorption rate, after absorbing a large amount of water after being rained, it may affect the quality of the aerated block, and the concrete that has reached strength and the concrete with saturated water content has a small softening property, which is less softening than natural stone, and almost does not affect the use; It has a great impact on the freshly poured concrete, and when it is serious, it will not reach the target strength.

Because the aerated concrete block has strong water absorption and large volume shrinkage, during masonry, in order to prevent the wall from shrinking cracks after construction, it is generally watered and moistened two days in advance.

However, the moisture content is not as large as possible, and the moisture content of aerated concrete blocks is generally required to be less than 15% (the moisture content of masonry required by different masonry materials is different).

1. The aerated block is hollow inside, and the bulk density is much smaller, which is generally used as a filling wall, and the self-weight load of the object is relatively small, which is conducive to the fiber structure of the cover. Ordinary concrete blocks have a slightly larger bulk density and are generally used in load-bearing walls.

2. The process is also very different, the aerated concrete block is formed by the chemical reaction of raw materials crushing, ball milling, metering, pulping, mixing, pouring, resting, cutting, steaming, and raw materials through high temperature and high pressure. Concrete blocks can be understood as cement concrete blocks, and in popular terms, cement bricks, this kind of masonry is formed by vibration. The thermal insulation and thermal insulation effect of aerated concrete blocks are higher than those of concrete blocks.
