50000 mยณ AAC Block Plant Process
Raw material process โ Batching and Mixing โ Pouring โ Static pre-curing โ Cutting โ Autoclaving Curing โ Finished product Processing
1. Raw Material Processing: Sand is crushed and ground to the desired fineness. Cement, lime, and gypsum are stored in silos, and aluminum powder is mixed with water to form an aluminum slurry.
2. Batching and Mixing: The various raw materials are weighed according to precise proportions and then thoroughly mixed in a mixer to form a uniform slurry.
3. Pouring: The mixed slurry is poured into steel molds. The size and shape of the molds can be designed to meet the desired block specifications.
4. Static Pre-curing: The molds containing the slurry are transported to a pre-curing area where the slurry gradually hardens under suitable temperature and humidity conditions to achieve initial strength. This process typically takes several hours.
5. Cutting: After the slurry is pre-cured, it is cut into the desired size and shape using high-precision cutting equipment like steel wire or blades.
6. Autoclave Curing: Blocks are placed in an autoclave and cured for several hours at temperatures of 175-200ยฐC and pressures of 10-15 bar, significantly enhancing the blocks’ strength and durability.
7. Finished Product Processing: After autoclave curing, the blocks are removed from the autoclave and transported to a storage area. After inspection and packaging, they are ready for shipment.
Raw Materials of AAC block
- Cement (Portland Cement): Acts as a primary binder, providing strength and durability to the blocks. Typically, 43 or 53-grade OPC is used.
- Fly Ash or Sand: Serves as the main siliceous material. Fly ash, a byproduct of coal-fired power plants, is an eco-friendly alternative to sand, providing the necessary silica content.
- Lime: A key calcareous material that reacts with other components to form the binding matrix and contributes to the chemical reactions during production.
- Gypsum: Added in small quantities to regulate the setting time and improve the workability of the mix.
- Aluminum Powder or Paste: Functions as a foaming agent. It reacts with lime and water to produce hydrogen gas, creating the characteristic porous, lightweight structure.
- Water: Essential for the hydration of cement and lime, and to facilitate the chemical reactions necessary for the setting and hardening of the blocks.
These materials are carefully proportioned and mixed to form a slurry, which is then cast, pre-cured, cut, and finally autoclaved to produce the finished AAC blocks.

FAQ
Accordion A 50,000 cubic meter AAC block plant primarily requires siliceous raw materials (sand, fly ash), calcium raw materials (quicklime, cement), a gas-generating agent (aluminum powder), and a small amount of additives. These raw materials are readily available in most regions of the world: sand can be purchased from local quarries, fly ash from nearby thermal power plants, and quicklime and cement from regional building materials suppliers, so there’s virtually no need to worry about raw material shortages.
Thanks to a fully automated PLC control system, this line only requires 4-5 workers per shift, primarily responsible for equipment monitoring in the control room, raw material supply inspections, and quality control of finished products. This is far fewer than a traditional semi-automated production line (which requires 8-10 people), significantly reducing labor costs.
Yes. The core cutting equipment (a 4.2-meter CNC cutting machine) offers flexible adjustments, capable of cutting standard block sizes such as 600ร200ร100mm and 600ร240ร180mm, as well as custom sizes tailored to customer needs (e.g., for special construction projects). No major equipment replacement is required; only minor adjustments to the cutting program and molds are required, making adjustments convenient and cost-effective.
The average daily energy consumption of this production line (including electricity and steam) is approximately 800-1000 kWh. Compared to the industry average, the autoclave uses a new insulation material, reducing heat loss by 8%, and the ball mill is equipped with an energy-saving motor. Overall energy consumption is 10%-12% lower than that of a conventional AAC production line of the same capacity, helping to reduce long-term operating costs.
This production line boasts environmentally compliant features, including dust emissions โค10 mg/mยณ, zero wastewater discharge, and daytime noise โค60 decibels, meeting the environmental standards of most Central Asian countries. Typically, if all application materials, including an environmental impact assessment report and equipment certification, are complete, environmental approval can be obtained within 2-3 monthsโa significantly more efficient process than production lines with poor environmental performance, which may take 4-6 months or even longer. We also provide guidance on preparing approval documents to expedite the approval process.
