Quality control for Autoclaved Aerated Concrete (AAC) blocks involves several steps, from inspecting raw materials to testing the final product for density, compressive strength, water absorption, and dimensional accuracy. Key control points include verifying the precision of the raw material mix, monitoring the autoclaving process, and conducting final product testing to ensure it meets standards for strength, durability, and safety before packing and dispatch. Quality control checkpoints

  • Raw material inspection: Before production, check that raw materials like cement, lime, gypsum, fly ash, and aluminum powder meet quality standards.
  • Production process: Monitor the slurry consistency and quality during mixing and casting. Ensure molds are clean and the autoclaving process (pressure, temperature, time) is controlled for uniform curing.
  • Final product testing: After production, test samples from each batch for key properties:
  • Density: Should be within the specified range, often 550–650 kg/m³.
  • Compressive strength: Must meet the minimum standard, typically 3.8–4.2 N/mm² or higher.
  • Water absorption: Should not exceed 10–15% by mass.
  • Dimensional accuracy: Check that the length, width, and height have a small tolerance, typically ±1–2 mm.
  • Soundness: The blocks should not show cracks after curing.
  • Packing and dispatch: Inspect for any surface defects like cracks or broken edges. Ensure blocks are stacked and packed correctly to prevent damage during transport.

Additional quality assurance

  • Certifications: Look for manufacturers with relevant certifications like ISO 9001 (quality management) or compliance with national and international standards like IS/ASTM.
  • Manufacturer reputation: Choose a reputable manufacturer that provides consistent quality and reliable products.
