- Компактиши Вибратсионӣ: High-frequency vibration, sometimes combined with lower pressure, consolidates the mix.
This stage determines the brick’s density, strength, and surface finish.
- Ejection & Handling: The newly formed “green brick” is gently ejected from the mold onto a conveyor belt or pallet. Advanced systems use robotic arms or stackers to organize bricks for curing, minimizing handling damage.
- Шифо додан: Unlike traditional bricks, these are not fired. Instead, they gain strength through curing:
- Steam Curing: Bricks are placed in a curing chamber and exposed to saturated steam (60-80°C) for 8-12 hours. This accelerates the pozzolanic reaction, yielding high early strength within days.
- Water/Air Curing: A slower process where bricks are sprinkled with water and covered for 2-3 weeks. Suitable for smaller operations.
