 Fresh Slurry Tank 📌 Purpose

• Stores newly prepared slurry from the main slurry mixer before it goes into moulds.

• Ensures uniform consistency and temperature for green cake formation.

• Acts as a buffer between mixer and casting line.

⚙️ Features

• Capacity: Sized according to plant output (typically 2–4 hours of production).

• Agitation: Mechanical stirrers to prevent settling of sand/fly ash.

• Discharge: Bottom cone or outlet pipe feeding directly into moulds.

• Sensors: Level indicator, temperature sensor, and sometimes slurry density monitor.

• Material: Mild steel with epoxy lining or stainless steel for corrosion resistance.

Scrap Slurry / Ground Pit Tank 📌 Purpose

• Collects leftover slurry or scraps from moulds, cutting areas, or cleaning operations.

• Stores scrap slurry temporarily for reprocessing or recycling.

• Minimizes waste and reduces production costs.

⚙️ Features

• Pit-type or underground tank with a hopper-like design.

• Agitation or recirculation system to prevent settlement.

• Can feed scrap slurry back to main slurry mixer after screening and adjusting water/chemicals.

• Often called ground pit tank, scrap tank, or recovery tank.

• May have grit/solid separation system to remove large debris before recycling.

Flow in an AAC Plant

1. Fresh Slurry → main slurry mixer → slurry storage tank → moulds.

2. After moulding → leftover slurry, spillages, or scraps → ground pit tank.

3. Scrap slurry is screened and recirculated into main slurry mixer.

ey Takeaways

• Fresh slurry tank: ensures continuous, uniform supply to moulds.

• Scrap slurry / ground pit tank: allows recycling, reduces waste, and optimizes cost.

• Both are essential for smooth AAC plant operation and maintaining green cake quality.

AAC Block Vertical Cutting Machine — Heavy duty model for AAC production with robust construction and long life. Commonly used in plants across India.

In an AAC manufacturing process, slurry is a mixture of:

• Cement

• Lime

• Fly ash (or sand)

• Gypsum

• Water

• Aluminum powder (added later for aeration)

 

The slurry must be uniform, well-mixed, and temperature-controlled before pouring into molds.

Purpose of Slurry Storage Tank

The slurry storage tank:

 

• Stores prepared slurry before casting

• Maintains homogeneous mixture (prevents settling)

• Controls temperature

• Ensits continuous supply to molds

• Helps in production buffer management

Main Sections of an AAC Plant 1️⃣ Raw Material Handling

• Cement silo – stores OPC cement.

• Lime storage – hydrated lime.

• Fly ash / sand storage – fine silica material.

• Gypsum hopper – for dimensional control.

• Conveyors or screw feeders move materials to weighing stations.

2️⃣ Weighing and Batching

• Scale hoppers weigh raw materials accurately.

• Batching ensures correct proportions for slurry consistency, block density, and strength.

3️⃣ Slurry Preparation

• Main slurry mixer blends all dry and wet ingredients.

• Aluminum paste is added at the end to produce hydrogen gas, which creates pores.

• Slurry is discharged into slurry storage tank or directly into moulds.

4️⃣ Moulding and Casting

• AAC moulds contain the slurry.

• Slurry expands into a green cake over 2–4 hours.

• Green cake dimensions are defined by mould length and width.

5️⃣ Cutting Machines

• Vertical cutting: cuts length and width of blocks.

• Horizontal cutting: cuts block height.

• Cutting ensures accurate block dimensions before autoclaving.

6️⃣ Pre-Curing & Handling

• Tilting tables and loading cranes move green cakes.

• Ensures cakes are stable and ready for autoclaving.

7️⃣ Autoclaving

• Wagon trolleys carry green cakes into autoclave.

• High-pressure steam curing (8–12 bar, 180–200°C) converts green cake into solid AAC.

8️⃣ Finished Block Handling

• Unloading trolley / cranes remove cured blocks.

• Blocks are stacked, stored, or transported to customers.

⚙️ Key Equipment in an AAC Plant

• Scale hoppers (cement, lime, fly ash/sand, gypsum)

• Main slurry mixer

• Slurry storage tank & service/makeup tank

• AAC moulds (single, multi-cavity, panel)

• Tilting tables

• Vertical & horizontal cutting machines

• Wagon trolleys

• Autoclave (pressure vessel for curing)

• Cranes & handling systems

�� Typical Plant Capacities �� Critical Factors for Quality

• Raw material quality (lime reactivity, sand fineness, cement grade)

• Precise weighing and batching

• Uniform mixing and correct aluminum dosage

• Proper pre-curing and cutting alignment

• Controlled autoclave temperature and pressure

⚠️ Common Operational Issues

• Uneven block density → improper mixing or incorrect slurry ratio

• Cracks in blocks → high expansion, wrong aluminum content, or pre-curing error

• Low strength → improper autoclave conditions or raw material issues

• Production downtime → machinery failure or maintenance delays

�� Modern Automation Trends

• PLC control for batching, mixing, and cutting

Load-cell-based weighing

Servo-controlled cutting machine

What AAC Blocks Are

AAC blocks (Autoclaved Aerated Concrete) are lightweight, cellular concrete products used widely in modern construction due to their benefits:

• Lightweight yet strong

• Thermal and sound insulation

• Fire resistance

• Faster construction

• Eco‑friendly and cost‑effective
  These blocks are manufactured by mixing raw materials like cement, lime, silica (fly ash or sand), gypsum, water, and a gas‑forming agent, followed by controlled expansion, cutting, and steam autoclave curing.

🧱 Production & Uses

• AAC blocks from Infra Block Industries are used for external walls, internal partitions, and compound walls across residential, commercial, and industrial projects.

How Green Cake Is Formed

1. Slurry (cement + lime + fly ash/sand + gypsum + water) is poured into mold.

2. Aluminum powder/paste is added.

3. Aluminum reacts with lime → hydrogen gas forms bubbles.

4. The mass expands like bread dough.

5. Pre-curing for 2–4 hours.

6. The material becomes soft-solid → this is the green cake.

Chemical Reaction

Aluminum reacts in alkaline condition:

2Al + 3Ca(OH)₂ + 6H₂O → 3CaO·Al₂O₃·6H₂O + 3H₂↑

Hydrogen gas creates millions of small air pores.
