Introduction of aerated block
With the rapid development of China's socialist construction, construction projects have made great progress, and capital construction investment has increased year by year. The development of building engineering needs more and better building materials. However, some old building materials in our country have many shortcomings such as heavy workload, low production efficiency, long capital construction period and heavy building weight, which have become a stumbling block to the development of building engineering. Therefore, the block building, large slab building, especially the light slab frame building system has made great progress, and a large number of new building materials have appeared. Among them, aerated block has a very important position.
Advantages of aerated block
1, the bulk density is light, which can reduce the weight and cost of the building and help improve the seismic capacity of the building.
Generally, the bulk density of aerated concrete is 500-850kg/m3, while the bulk density is above 450kg/m3, and its weight is only 1/4 of clay brick and 1/4 of ordinary concrete. It is an ideal lightweight material for high-rise buildings, super-high-rise buildings and large-space structures, which can reduce the self-weight of buildings 1000kg.
Lightweight of buildings can greatly improve the seismic performance of buildings, because earthquakes are the product of building quality and acceleration caused by earthquakes. Obviously, light buildings have low mass and low seismic force.
2. Good thermal insulation performance and low thermal conductivity.
The thermal conductivity of aerated concrete with bulk density of 400-800 kg/m3 is usually between 0.08-0. 1.5 kcal/m * * degrees, which is only 1/4- 1/5 of clay brick and1/5-of ordinary cement concrete.
3. Machinability
It can be processed like wood, sawed, planed, drilled and nailed, which is beneficial to construction and can be used on site.
4. Aerated block has strong compression resistance.
Experiments show that the compressive strength of aerated block is more than 25 kg/cm2, which is equivalent to that of clay brick 125 and lime-sand brick.
5, aerated block high temperature resistance
When the temperature of aerated concrete is lower than 600℃, its compressive strength increases slightly, and when the temperature is around 600℃, its compressive strength is close to room temperature, so the fire resistance of aerated concrete as a building material reaches the national first-class fire protection standard.
Aerated block specification
General specifications of aerated block are 600mm×200mm, 600mm×250(240)mm and 600mm×300 (length× height).
How much is the aerated block per cubic meter?
Ex-factory price of ash aerated gas 155 yuan, ex-factory price of sand aerated gas is 205 yuan, and freight within 20km 17 yuan/square. Recommended by aerated block manufacturer

Specification for aerated block masonry
(1) The construction site is divided according to the building number, and the reinforcement planting project on the construction site can only be started after completion.
(2) The on-site storage site shall be compacted, leveled, free of water and neatly packed. Handle with care during shipment to avoid damage. And stacked according to the drawings to avoid reducing secondary transshipment.
(3) According to the wall size and block specifications, the layout design shall be carried out before masonry, so as to minimize the amount of on-site cutting. According to the thickness of the block, the clearance height of the structure and the size of the door and window openings, the typesetting design of the facade and section is effectively arranged to avoid waste.
(4) The position of aerated concrete block shall be layered on the structural wall according to the elevation line of+1000mm, and the thickness of mortar joint shall be arranged.
