• 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.

Fire Resistance: AAC blocks can withstand high temperatures, providing essential fire protection in industrial settings

Precision and Consistency: AAC blocks are manufactured in precise dimensions, ensuring uniformity and reducing the need for on-site adjustments. This precision contributes to a neater construction process and a more aesthetically pleasing finish.

Thermal Insulation:Their excellent thermal insulation properties help maintain comfortable indoor temperatures, reducing energy costs for heating and cooling.
