AAC block manufacturing process
The AAC block( autoclaved aerated concrete block) is a porous and lightweight aerated concrete product made from siliceous and calcareous materials with aluminum powder through a series of processing(raw material processing, dosing and mixing, Casting, Rinsing and Pre-curing, Demoulding and cutting, autoclave curing).
Raw Material Processing
A: Siliceous materials: Fly ash / Sand /Tailings containing silicon
B: Calcareous material: Lime block + cement + gypsum
C: Gas former: Aluminum powder
Flyash or sand is first ground by ball mills and transferred to a slurry tank for later use. Crushed lime stones by jaw crusher are sent into a ball mill for fine grinding to make powder lime and storage in a silo. Aluminum powder is conveyed to a mixer to form a suspension with water.
Dosing and Mixing
The critical material fly ash is turned into slurry first. Fyl ash slurry, lime powder, and cement are measured separately and added to the pouring mixer for mixing. A certain amount of steam will be added when necessary to make sure the temperature for mixing reaches 40-45 ℃. The blending process lasts for 2-3 minutes. Before pouring, the aluminum suspension will be poured into the slurry and mixed for less than 40 seconds. The whole batching system adopts centralized computer control to realize automatic batching control, remote control, and fault diagnosis.
Moulding, Rinsing, and Pre-curing
The well-stirred slurry is poured into the molds which are painted with oil in advance to prevent sticky. Bubbles are first eliminated after the pouring. The molds are transferred by a trolley to the pre-curing room which leaves time for the expansion of the slurry resulting in aluminum reacting with lime and water. It takes about 90-130 minutes with an automatically controlled temperature of 40-45℃.
Demoulding and Cutting
When the slurry reaches strength, the mold will be moved out from the curing room. The crane hoist lifts up the mold and releases the green cake after a 90-degree tilting. Then the green cake is cut by horizontal and vertical cutting machines. Before going into autoclaves, it is hoisted to the turning and peeling device, and the bottom waste is recycled.
The hauling machine transfer and stack the cut green cake together with the side plate on the rails to enter the autoclave. The autoclave curing will last 8-12 hours to ensure the hardness and chemical properties of the final blocks.
Packing and Loading
The finished blocks out from the autoclave will be packed with waterproof materials and loaded on trucks for delivery.
AAC block plant setup cost
The investment for an AAC block plant is varied in several aspects. For example, the scale of production decides how much equipment is needed, and how large the area of the factory will be. The common capacity for the AAC block plant is 100,000 to 300,000 cubic meters per year. The cost for a plant like this may range from $300,000 to $2,000,000.
For your reference, here is a detailed cost analysis for the setup of an AAC block plant. You may have noticed that even if the plant has the same capacity, the cost may still be different according to the configuration. Please note the above figures are only estimated numbers. The actual cost will depend on the specific planning situation.

Why Build the aAC block plant?
The market for autoclaved aerated concrete was worth USD 4720.79 million in 2021, and it is anticipated to grow to USD 8766.98 million by 2030, with a CAGR of 7.12% during the forecast period of 2022–2030. (from globe newswire). India has great potential for the AAC block business since now the AAC block only takes up 7-8% of its building bricks. To look in a wider view, North America, Europe, Asia Pacific, Latin America, and Middle East & Africa are all large consumers of AAC blocks.
Another critical factor that makes the AAC block plant promising is the low-carbon foot. With the advancement of science and technology, the rapid development of urbanization, and the expansion of building scale, the consumption of autoclaved aerated concrete blocks also increases. At the same time, the development of building materials is not only the direction of low energy consumption but also building energy saving has attracted people’s attention. Energy saving and emission reduction of autoclaved aerated concrete blocks have increasingly become the focus of attention. People’s life is how to balance building energy conservation and emission reduction. This will be the development direction of the construction market, in line with the requirements of the standard. AAC blocks can not only save energy and reduce emissions, but also can recycle waste.
Advantages of aAC block produced with our machine
Autoclaved aerated concrete blocks weigh 500-700kg/m3, which is 1/4-1/5 of clay bricks and 1/5 of most concrete. This is a lighter type of concrete. Compared with most brick-concrete structures, the self-weight is reduced by more than 40%.
Heat preservation and insulation
AAC blocks have very low thermal conductivity, and the thermal insulation effect is 6 times that of clay and 12 times that of ordinary concrete. A 200MM thick block used for external walls can meet the strict requirements of heat preservation and energy saving without auxiliary insulation materials.
The sound insulation volume of the wall built by aac blocks can reach 30-50 decibels. The wall has the dual effect of sound insulation and sound absorption.
Impermeable and waterproof
The autoclaved aerated concrete block is formed by foaming, and the internal pores are independent and closed, with a uniform size and diameter of about 1MM, which can effectively block water diffusion. And due to the use of mortar masonry, the thickness of the ash joint between the products is not more than 5MM, further improving the overall anti-seepage performance of the wall.
The autoclaved aerated concrete block itself is an inorganic material, a non-combustible material, and has excellent fire performance. The experiment proves that autoclaved gas block product is an ideal fireproof material, and the fire resistance limit of 10CM wall can reach more than 4 hours, which is widely used as a firewall.
As the AAC blocks are generally used for wall structure, the dimension accuracy is essential. The accuracy can reduce the trimming of construction and save motar and other finishing materials.
Specification of AAC blocks
Autoclaved Aerated Concrete block is referred to as AAC block. It is a precast, lightweight building material comprised of sand, cement, lime, gypsum, water, and an expansion agent from natural raw materials. The material acquires a cellular structure as a result of the expanding agent’s creation of air pockets. In an autoclave, a high-pressure vessel, steam under pressure is used to cure AAC blocks. This procedure produces a construction material with exceptional thermal insulation capabilities, fire resistance, and sound insulation that is lightweight, dimensionally precise, and very durable. The ease with which AAC blocks can be handled, cut, and installed as well as how quickly and cheaply they can be installed make them a popular choice for building projects.
