Whether foamed concrete block bricks can be used in civil housing

Foamed concrete block bricks can be used in civil houses, not only can be used in civil houses, foamed concrete block bricks also have the following advantages:

1. When building the wall, the ash joints are reduced, the use of red bricks requires mortar per cubic wall, the use of foamed concrete blocks only needs m3 mortar per cubic wall, and the cost of mortar can be saved by about 14 yuan per cubic meter of the wall.

2. The stucco mortar can be reduced by about 1 3, because the production specifications of the mold are extremely smooth, the error is within 1, and the whitewashing of each cubic block can save about 8-10 yuan compared with red bricks. Handling labor saving, because the cement foamed concrete block itself is lightweight, such as high floors, large consumption, saving about 30% of labor handling wages.

3, the wall aging is fast, can greatly save the construction period, from the practical operation to conclude that the red brick wall each skilled worker only builds about m3 a day, and the foamed concrete can be built about 6 m3 a day, according to the calculation of 50 yuan per person per day, each cubic meter can save nearly 16 yuan only for the wall fee.

4. Foamed concrete block is a new type of environmentally friendly material, and the state is exempt from wall modification, and the construction unit using red brick must pay 8 yuan per square meter for wall modification.

5. The grade of the house has been improved, and the thermal insulation, sound insulation, heat insulation, seismic resistance, and energy-saving performance have been fully reflected, which can increase the selling point of commercial housing by 3%, and has become the preferred condition for users to buy houses in major and medium-sized cities.

6. The comprehensive total cost can be reduced by 6-8% compared with red bricks, so cement foaming is used.

Can foam concrete blocks be better than red bricks in terms of thermal insulation and moisture-proof, frost and compression resistance, hardness, investment funds, and appearance.

It can be used mainly for infill enclosure walls of frame structures. The main advantages are light weight and thermal insulation. The lightness of foam concrete depends on the foam density inside it, and the national regulations are only a range, and the flexibility is high.

It is a lightweight wall material, which is conducive to reducing the overall weight of buildings, especially high-rise buildings. But its structure is not very good, it is easy to produce fission in the event of a strong earthquake, etc., and the foam density is too large, too light is equivalent to foam. . .

Foamed concrete, also known as foam concrete or lightweight concrete, foamed concrete is an inorganic material that will not burn through the foaming system of the foaming machine, so as to have good fire resistance, and can be used in buildings.

Foamed concrete, also known as foam concrete, is a new type of concrete, which has the advantages of heat preservation, heat insulation, fire prevention, sound insulation, light weight, etc., and has been widely used in high-end buildings.

OK. Aerated concrete block masonry is generally used in infill walls, and the strength grade of the blocks used is generally partition walls and exterior walls A5. The strength of the mortar is not less than m5.

Before aerated concrete block masonry, the block arrangement diagram should be drawn according to the plane and elevation of the building. Set up the skin number rod at the corner of the wall, draw the number of blocks and the height of the block on the skin number rod, and pull the alignment line between the upper edge lines of the relative blocks, and build masonry according to the alignment line.

The masonry surface of aerated concrete blocks should be sprinkled with an appropriate amount of water. Special tools should be used for masonry aerated concrete (shoveling, sawing, drilling, hollowing, flat frame, etc.).

If there are no effective measures for aerated concrete block walls, they shall not be used in the following parts:

1. The part below the moisture-proof layer of the building;

2. Long-term immersion or chemical erosion environment;

3. Walls that have been in the environment of vibration sources for a long time;

4. The surface of the block is often in a high temperature environment of more than 80. No scaffolding eyes shall be left on the aerated concrete block wall. The block walls on each floor should be built continuously, leaving no joints. If it is necessary to leave it as a diagonal one, or it should be interrupted on the side of the door and window opening.

To see whether the exterior wall i is a load-bearing wall, the aerated concrete block can not be a load-bearing wall, and the outer wall of the frame structure can be an aerated concrete block.

Procurement of building materials according to various performance requirements. If the compressive resistance, bending strength and other requirements meet the design, of course, it can. But generally speaking, autoclaved aerated concrete blocks belong to non-load-bearing bricks, which are mostly used in buildings with frame structures, and the light weight, sound insulation, and heat insulation effects are better than those of general cement bricks, Shanghai slag bricks, sand bricks, etc.

The disadvantages are poor impermeability effect and low strength.

Generally, the compressive strength can not be reached, but this is also a trend, self-insulating bricks instead of external insulation.

Aerated concrete blocks can be used as low-rise load-bearing exterior walls and high-rise structural infill exterior walls, as well as infill walls and partition walls.

Energy saving, environmental protection, good sound and heat insulation.

It has been highly recommended by the country.

To buy aerated concrete block equipment, you can consult Henan Shenglong Machinery Professional aerated concrete block equipment manufacturers.

Red brick and foam concrete (aerated concrete) blocks are both called masonry materials; Red bricks can be used for load-bearing walls. Aerated concrete blocks can only be used in the infill walls of frame structures, not load-bearing walls.

The aerated concrete blocks of red brick and frame structure cannot be simply compared with the cost per square meter, because the functions of the two are different; If both are used in the envelope (internal partition wall), aerated concrete blocks are more economical.

No, the foundation is generally buried in the ground, and aerated blocks cannot be used in wet blocks.

If there are no effective measures for aerated concrete block walls, they shall not be used in the following parts: 1. The parts below the indoor ground elevation of the building; 2. Long-term immersion in water or frequent alternating dry and wet parts; 3. Subject to chemical environment erosion (such as strong acid, strong alkali) or high concentration of carbon dioxide and other environments; 4. The surface of the block is often in a high temperature environment of more than 80.

Mainly due to the large number of pores in aerated concrete, it cannot withstand freeze-thaw cycles, so it cannot be used for building foundations.

It's like a water pipe can be frozen and cracked in winter.

Autoclaved aerated concrete blocks can be used as the façade of a building, but this façade needs to be a non-load-bearing façade. Aerated blocks are generally used as partition walls.

Generally, the compressive strength cannot be reached.

But it is also a trend to replace external insulation with self-insulating bricks.

Hello・Do not use on the base part.

Secondly, the design of the specified process: autoclaved aerated concrete block design specified process (1) If the aerated concrete block does not take effective measures, it should not be used in the following parts:

1) Buildings below 1 (except for non-load-bearing inner partition walls in basements).

2) Long-term immersion in water or frequent alternating wet and dry areas.

3) Environments subject to chemical erosion. Such as strong acid, strong alkali or high concentration of carbon dioxide, etc.

4. The surface of the block is often in a high temperature environment of more than 80.

2) The strength grade of the block for the wall should be A25 or more. When masonry, it is advisable to use special binders or masonry materials that conform to the "masonry mortar and plastering mortar for autoclaved aerated concrete" (JC 890-2001).

3) The thickness of the internal and external walls of the autoclaved aerated concrete block should be determined according to the technical and economic comparison and the requirements of the building structure. It shall not be less than the minimum thickness value determined by the calculation of thermal codes such as "Energy Conservation Design Standards for Civil Buildings", "Thermal Design Regulations for Civil Buildings", "Energy Conservation Design Standards for Residential Buildings in Hot Summer and Cold Winter Areas" and other thermal specifications and building sound insulation requirements. The thickness of the interior wall should be greater than or equal to 100, the thickness of the external wall of civil buildings should be greater than or equal to 200, and the thickness of the external wall of industrial buildings should be greater than or equal to 150.

4) The partition wall of the bathroom should be waterproof to avoid the alternation of dry and wet on the wall or the damage of local freezing and thawing.

Hope it helps.

If there are no effective measures for aerated concrete block walls, they shall not be used in the following parts:

1) The part below the indoor ground elevation of the building;

2. Long-term immersion in water or frequent alternating dry and wet parts;

3. Subject to chemical environment erosion (such as strong acid, strong alkali) or high concentration of carbon dioxide and other environments;

4. The surface of the block is often in a high temperature environment of more than 80.

No, foam concrete blocks can only be used for filling. Fences, etc., where there is no load-bearing, ordinary bricks have high compressive resistance.

Not foam concrete blocks are filled bricks and cannot be load-bearing ordinary bricks are load-bearing bricks.
