300,000 m3/Year AAC Block Plant Process

Raw material process → Batching and Mixing → Pouring → Static pre-curing → Cutting → Autoclaving Curing → 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 175-200°C 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.
