Sand aerated block construction process? What mortar is used for aerated concrete blocks

Special mortar for aerated concrete block is a special mortar developed according to the porous characteristics of aerated concrete block.

1. Aerated concrete is a porous structure with many pores inside. The holes are closed round holes, and the poor quality holes are continuous through holes. The porosity of aerated concrete is generally 65 75, and the maximum can reach 80.

2. When using the traditional masonry method, the sintered solid clay bricks should be thoroughly watered with water the day before masonry so that it can absorb enough water, and then plastered with mortar masonry. At this time, the water on the surface of the brick has been saturated and no longer absorbs water from the mortar, so as to ensure that the mortar is fully hydrated, the strength develops normally, and the mortar and the brick can be firmly bonded.

3. However, for aerated concrete, due to the slow water absorption speed and small water absorption of aerated concrete, the advanced pouring method is not suitable for aerated concrete.

4. When the traditional mortar masonry aerated concrete, the mortar is slowly absorbed by the aerated concrete in the water, resulting in insufficient cement hydration, the strength can not develop normally, the mortar bonding strength and compressive strength are low, the mortar and block binding are not the company, which affects the quality of the masonry, and the gypsum layer cracks, hollows out, and even falls down easily.

Aerated concrete blocks:

Aerated concrete block is a new type of building material that is light in weight, porous, heat insulation, good fire resistance, nail resistance, saw resistance, planing resistance, and resistance to cutting. Back in the early 30s of the 20th century, such products began to be produced in China and were widely used. For example:

Shanghai International Hotel, Shanghai Tower, Fuzhou Building, People's Bank of China Building and other high-rise buildings. It is an excellent new building material with the advantages of environmental protection.

Concrete block masonry is divided into two types: free plastering and thin plastering

1. The width of the plaster-free plaster joint is less than or equal to 3mm, and it is necessary to use a special mortar for aerated blocks, and the tie ribs are made of flat steel;

2. The width of the thin plastering mortar joint is about 10mm, the bonding mortar is made of ready-mixed DMM5 or DMM10, and the plastering mortar is made of DPM5 or more strength of the plastering mortar, and the strength of the plastering mortar is best not higher than M15, otherwise the risk of cracking is greater.

Mixed mortar (cement, medium sand, lime plaster, admixture) or special block masonry binders can be used.

Summary. Dear, hello, I am happy to answer for you, how much cement and sand is used for masonry a cubic aerated block, the dosage is as follows: 1, (200 walls, horizontal ash joints 15, vertical ash joints 20).

The amount of 1 cubic aerated concrete brick = 1 piece. The amount of 1 cubic aerated concrete mortar = cubic 2, (240 walls, horizontal ash joints 15, vertical ash joints 20). The amount of 1 cubic aerated concrete brick = 1

The amount of 1 cubic aerated concrete mortar = cubic 2, (240 walls, horizontal ash joints 15, vertical ash joints 20). The amount of 1 cubic aerated concrete brick = 1

Dear, I hope mine can be helpful to you, and I wish you a happy life.

Dear please be able to give me a thumbs up and follow <>

How much cement sand is used for masonry of a cubic aerated block: 1 cubic meter of bricks with cement mortar, about 52 59 cement and 328 sand are needed. (200 walls, horizontal ash joints 15, vertical ash joints 20) 1 cubic aerated concrete brick dosage hall = 1 piece.

The amount of hidden concrete mortar before 1 cubic aerated mixed attack = cubic (240 walls, 15 horizontal ash joints, 20 vertical ash joints) 1 cubic amount of aerated concrete bricks = 1 piece. 1 cubic aerated concrete mortar amount = cubic emphasize: this is only a theoretical value, in fact, due to the wrong regret of hand joints and other reasons, the number of masonry blocks will increase, and the amount of mortar will also increase slightly.

Dear, hello, I am glad to answer for you: how much cement sand is used to build a cubic aerated block Answer: 52 59 cement and 328 sand are used to build a cubic aerated block.

200 walls, horizontal ash joints 15, vertical ash joints 20) 1 cubic aerated concrete brick amount = 1 piece. The amount of 1 cubic aerated concrete mortar = cubic (240 walls, 15 horizontal ash joints, 20 vertical ash joints) 1 cubic amount of aerated concrete bricks = 1 piece. 1 cubic aerated concrete mortar amount = cubic emphasis:

This is only a theoretical value, in fact, due to misjoints and other reasons, the number of masonry blocks will increase, and the amount of mortar will also increase slightly.

The amount of Zen with the body is as follows: 1, (200 walls, horizontal ash joints 15, vertical ash joints 20). 1 cubic plus line of smart air concrete bricks = 1 piece.

The amount of concrete mortar for 1 cubic aerated Hejia = cubic 2, (240 walls, 15 horizontal ash joints, and 20 vertical ash joints). The amount of 1 cubic aerated concrete brick = 1 piece. The amount of 1 cubic aerated concrete mortar = cubic meters.

The ratio of cement and sand required to build a cubic aerated block is usually 1:6, that is, 1 part cement corresponds to 6 parts sand. If you want to know the specific amount of cement and sand required to build one cubic aerated block, you can refer to the following formula:

Amount of cement = volume of masonry 7

Sand usage = masonry volume

Among them, the masonry volume refers to the volume of the aerated block to be built, and the unit is cubic meters (m).

For example, if you are building a cubic aerated block with a volume of 1 cubic meter, you will need 1 7 = cubic meters of cement and 1 cubic meter of sand.

Please note that the above formula is for reference only, and the actual dosage may vary due to factors such as material quality, masonry process, etc. It is recommended that you ask a professional for the specific dosage before construction to ensure the quality of construction.
