The Advantages of AAC Blocks and AAC Wall Panels

“Autoclaved Aerated Concrete Block”, abbreviated as aerated block and aerated brick, or AAC block,is an aerated concrete block produced by high-temperature autoclave equipment process. “Aerated Block” can be understood as a simplified or general name. It should cover a wider range of AAC products, that is, AAC blocks,AAC bricks,AAC wall panel and lintels produced by various other processes including steaming autoclave.

Features and advantages

1. Light weight

The general weight of aerated concrete block is 500-700kg / m3, which is only equivalent to about 25% of clay brick and 20% of ordinary concrete block. Compared with ordinary brick concrete structure buildings, the self weight of AAC block building is reduced by more than 40%.

2. Super thermal insulation performance

The thermal conductivity of AAC product is 16% of that of ordinary concrete block, and the thermal insulation performance is much better than that of 240mm thick clay brick wall.

3. Strong seismic capacity

AAC block and AAC panel are lightweight, good overall performance and small inertia force during earthquake, so it has a certain seismic capacity.

4. Good processing performance

Aerated concrete and AAC products have good processing performance and can be sawed, planed, nailed, milled and drilled, which brings great convenience and flexibility to the construction.

5. High temperature resistance

When the temperature of aerated concrete is below 600 ℃, its compressive strength increases slightly. When the temperature is about 600 ℃, its compressive strength is close to the compressive strength at room temperature, and the fire resistance reaches the national first-class fire protection standard.

6. Good sound insulation

The internal structure of AAC block is like bread, with a large number of closed pores evenly distributed, so it has the sound-absorbing performance that ordinary building materials do not have.

7. Strong adaptability

AAC block and AAC wall panel can be customized according to different local raw materials and conditions. Raw materials can be river sand, fly ash, mineral sand, etc. according to local conditions. Waste can be utilized, which is conducive to environmental protection and truly turn waste into treasure.

What Should Be Considered When Planning to Establish an AAC Production Line

  1. Is the AAC production line design reasonable?
  2. Unreasonable design will seriously affect AAC block and AAC wall panel productivity and efficiency.
  3. Equipped with side plates, steaming cars, and whether the moldsare reserved. 

If it is just for price considerations, the number of AAC equipment is too theoretical, then in the production process, it will be the same as the relay, the production is very tight, and a little slower, it will affect the entire AAC production. Therefore, when we make AAC plans for our customers, we have more reserved side panels, steaming trolleys, and AAC mold boxes. The price is higher for sure.

  1. Is the AAC block production process good?

A.The fineness of the sand is the core technology (the sieve residue is below 25%), the coarse sand is easy to sink, and the ball milling time is 6-8 hours (the steel section inside is adjusted to adjust the fineness of the sand)

B.The higher the silica content, the higher the quality of the brick (qualified at more than 65%, preferably more than 75%). Of course, when the silica content is low, it can pass the heating temperature (regulated at 20-30°). In order to catalyze the reaction rate.

C.Control the mixing time (the sanding section needs to be stirred for two hours, and the mixing is stirred for 4 minutes, otherwise the cement will not function).

D.Pre-curing time has a great relationship with temperature, and the pre-curing temperature is about 50-55 degrees.

E.Temperature control (45-50 degrees, depending on the material) is critical to the amount of raw materials used. If the temperature of the stirring is too low, the utilization rate of the lime will be lowered, and the gas is not ideal, which will increase the amount of the slurry, resulting in an increase in cost and an increase in the specific gravity of the block. If the temperature is too high, the chemical reaction is too fast and there is no curing, and the mold will collapse. Under normal circumstances, each mold needs (4.2 meters of mold) lime 295 kg, cement 270 kg, but when the silica content is low, without heating, the lime should be 350-430 kg, the cement does not change. With an annual production capacity of 50,000 cubic meters, the temperature control is not good, and it may use more about 2200 tons of lime annually.

F.In the case of low silica content and no heating, it is necessary to add a dry powder meter and firstly mix the cement so that the cement can fully absorb the water, otherwise it will affect the strength of the aerated block.

G.Domestic electronic measurement can reach up to +-3%, the error of 1000 kg is 30 kg, and 2000 kg is 60 kg. The measurement is to ensure its error, long-term stability and stability. The powder we use is called the Italian METTLER brand with a measurement error of 1%. The powder error is too large to affect the composition and yield.
  1. The sand began to chemically react at a pressure of 1.1-1.2 MPa at a pressure of more than 175 °C. The hydration reaction did not reach a constant pressure of less than 8.5 hours, and the intermediate strength of the block was very low. If the pressure is too large (such as 1.3Mpa), the scrap rate will reach 15%. There is alsoa lot of steam. The pressure of fly ash in the booster is preferably 0.9-0.95Mpa, and the actual constant pressure is 8 hours.

J.The comprehensive strength depends on the level of foaming, so that it foams low and reduces the amount of aluminum powder.

K.Why most of the customers’ finished block strength with only 2.8Mpa and high cost, mainly due to process problems, silica content of lime, temperature, pressure and so on. The same equipment, different processes, can cause a cost difference of 20 yuan(2.85usd) / cubic. (The difference in process will mainly affect the amount of sand/flyash, , lime, cement and aluminum). With an annual production capacity of 50,000 cubic meters, the cost difference is 6 million yuan (142,500usd).

When comparing prices, it is better to consider the following factors:

A.Size and quantity of autoclave.

B.Boiler tonnage

C.Cutting quality of the cutting machine. Cutting precision reaches: ±1mm. The cutting machine is relatively stable with gear transmission. Some use chains, which are easy to loosen and the cutting size is easily deviated.

D.Side plates, steaming cars, number of molds.

E.Equipment material thickness. For example, some manufacturers use too thin materials, mold boxes, side plates have been deformed after less than a year. Our mold boxes, side plates, will not be deformed for almost ten years.

For example, Hongfa mold uses 10mm original plain manganese steel plate Q345, mold box weight is 1700kg, other manufacturers mold is much lighter in weight, Hongfa side plate uses 10mm thick plain manganese steel plate Q345, each piece weighs 588kg, other manufacturers less then 400kgs, Hongfa steam car is 448kg, and the others are only 220kg each.

F.Main power control system main components use Siemens, Omron, ABB, Schneider and other electronic components.

5.The yield of the production line. Hongfa can reach 99.9%.
6.Reasonable recycling of waste water and waste.
7.How to save electricity, save fuel and save steam. Save as much as possible.

8.The steel section of the ball mill is not chrome steel, the chrome steel section is more durable, and the general steel section is not durable.

9.The maintenance cost of the equipment is 2 yuan(0.285usd) per cubic meter, while the equipment maintenance cost of other supplier is 5 yuan(0.714usd) per cubic meter.
10.Hongfa equipment has a design life of 20 years. Actual use can be up to 30 years.
