• 1. Raw Material Selection and Preparation

  High-Quality Raw Materials: We use premium raw materials, including silica sand, lime, cement, gypsum, and aluminum powder, to ensure our AAC blocks meet top industry standards.
  Precise Mixing Process: The materials are accurately measured and mixed, with aluminum powder acting as a foaming agent, creating tiny air bubbles for aeration.

• 2. Slurry Formation and Casting

  Creating the Slurry: The mixed materials form a slurry, poured into molds, where a chemical reaction causes it to expand, forming a lightweight, aerated structure.
  Pre-Curing Stage: The molds are left to pre-cure for several hours, allowing the slurry to solidify into a “green cake” with the desired aerated structure.

• 3. Cutting and Autoclaving

  Precision Cutting: Once hardened, the green cake is cut into blocks of specified dimensions using precision machines, ensuring uniformity.
  High-Pressure Autoclaving: The cut blocks are cured in an autoclave at high temperatures (180-200°C) and pressure (12 bar) for 10-12 hours, achieving final strength and stability.

• 4. Quality Assurance and Packaging

  Rigorous Quality Control: Each batch undergoes tests for compressive strength, density, fire resistance, thermal insulation, and sound absorption to meet SBW Buildtech’s standards.
  Finishing and Packaging: The blocks are carefully packaged and prepared for shipment, ensuring protection during transportation.

Health and Indoor Air Quality: AAC blocks do not emit harmful substances, promoting better indoor air quality and a healthier environment for office occupants.

Fire Safety Standards Compliance: AAC blocks meet stringent fire safety standards, ensuring compliance with local building codes and regulations for office spaces.

Sound Barrier: AAC blocks offer superior sound insulation, minimizing noise pollution and enhancing the working environment.

Conclusion

SBW Buildtech’s commitment to excellence in AAC block manufacturing ensures that hospitals benefit from superior fire resistance, energy efficiency, sustainability, structural stability, and acoustic performance. These attributes make AAC blocks an optimal choice for creating safe, efficient, and healing environments in healthcare facilities.
