What Is an AAC Production Line?

An AAC production line is a fully automated or semi-automated system designed to produce Autoclaved Aerated Concrete (AAC) blocks.
Using materials like cement, lime, fly ash (or sand), gypsum, and aluminum powder, AAC blocks offer benefits such as:

Lightweight
Excellent thermal insulation
Soundproofing
Fire resistance
Fast construction speed
Low environmental impact

With the global adoption of green construction materials, AAC blocks are becoming the preferred alternative to clay bricks and concrete blocks.

AAC Production Line Process

The production process of the AAC Production Line follows a strictly controlled sequence of steps:

Raw material preparation: Crush and sieve sand, cement, lime, and fly ash. Then store them in silos.
Mixing: Mix these materials with water in exact proportions to make a slurry. Add aluminum powder to start foaming.
Casting and rising: Pour the slurry into molds. The aluminum reacts with other components, making the slurry expand and form air bubbles.
Pre-curing: Let the material set in the molds for a few hours to gain initial strength.
Cutting: After pre-curing, use wire saws to cut the material into blocks of precise sizes.
Autoclaving: Put the cut blocks into an autoclave. Cure them at high pressure (up to 12 bar) and high temperature (about 180–200°C) for 8–12 hours. This helps form strong calcium silicate hydrate bonds.
Packaging and storage: Inspect the finished blocks, package them, and store them for distribution.

Raw Materials Used in AAC Block Production

Sand: A primary aggregate, often sourced locally to reduce transportation costs.

Kuchli kul: A byproduct of coal-fired power plants, reused in AAC to minimize waste.

Tsement va ohak: Essential binders that react to form the material’s structure.

Aluminum powder: A small but critical component for creating the aerated structure.

Suv: Used in mixing and curing, with many plants implementing water recycling systems.

AAC Production Line Equipment List

1. Raw Material Handling Equipment

Crusher: Crushes raw materials such as sand and lime to the specified particle size. Jaw crushers are used for hard materials, and impact crushers are used for fine crushing.

Screener: Uses vibratory screening to remove impurities and make sure raw material particles are uniform in size.

Storage Silo: Stores pre-treated raw materials. It has a level meter and dust removal device to keep production running continuously and meet environmental protection requirements.

Weighing Scale: Belt or spiral scales accurately measure raw material quantities to minimize formulation errors.

2. Mixing and Foaming Equipment

Forced Mixer: Mixes solid raw materials and water at high speed to form a uniform slurry, laying the foundation for foaming.

Aluminum Powder Mixing Tank: Mixes aluminum powder suspension at low speed to prevent sedimentation and ensure uniform dispersion.

Foaming System: Aluminum powder suspension is injected in proportion to react with the slurry to generate bubbles, which are then linked to the mixer for automated control.

3. Casting and Forming Equipment

Molds: Custom-made high-strength steel with a special surface treatment, adjustable in size to accommodate different product specifications.

Casting Machines: Precisely control the slurry injection volume, and some are equipped with automatic travel to prevent material shortages or overflow.

Curing Chamber: A constant temperature and humidity environment ensures slurry aeration and initial setting, resulting in a uniform porous structure.

4. Cutting Equipment

Turning Table: Driven by hydraulics, it rotates molds and blanks smoothly—this makes demolding and cutting easier.

Wire Saw: Uses multiple sets of high-strength steel wires for high-speed cutting. A CNC system ensures cutting accuracy down to the millimeter. For large wire saw equipment, it can do continuous cutting at multiple stations.

5. Autoclave Curing Equipment

Autoclaves: Large pressure vessels cure blanks at temperatures of 180–200°C and pressures of 10–12 bar, forming high-strength calcium silicate hydrates. Equipped with safety interlocks.

6. Auxiliary Equipment

Steam Boilers: Supply stable steam for autoclaves and curing chambers, with various heating options available.

Air compressor: Provides compressed air for pneumatic equipment, ensuring valves, clamps, and other devices work properly.

Conveyor belt system: Transports materials through the entire process. Uses belt or chain conveyors (chosen based on material needs) for automated, continuous movement.

Nazorat tizimi: PLC or DCS systems monitor and adjust production parameters in real time. They record data for management and traceability, and help resolve issues promptly.

Applications of Autoclaved Aerated Concrete Block

AAC’s versatility makes it suitable for a wide range of construction applications:

Residential buildings: Walls, floors, and roofs in houses and apartments.

Commercial structures: Offices, malls, and hotels benefit from its insulation and fire resistance.

Industrial facilities: Used for partitions and external walls due to durability.

Infrastructure projects: Bridges, tunnels, and sound barriers leverage its lightweight properties.

Benefits of Using AAC Block

Seismic Resistance: Low density, good integrity, and low seismic inertia.

Soundproof: 10 cm wall insulation of 41 dB, blocking sound transmission and improving indoor comfort.

Quick: Large panels can be installed at 8-10 m²/person/shift, reducing construction time by 40%.

Green: Solid waste utilization rate ≥ 60%, zero wastewater discharge.

Precision: CNC cutting, finished product tolerance ≤ ±1 mm, thin-layer masonry reduces mortar consumption by 70%.

Environmental: Uses industrial waste (fly ash), resulting in lower production energy consumption than traditional concrete.
