1. Quality Control of Raw Materials

All necessary tests and measurements are continuously performed on raw materials. If the quality is confirmed and specifications meet the requirements, the materials are approved for use. For example, the raw materials used in the production of autoclaved aerated concrete (AAC) include cement, quicklime, silica, gypsum, aluminum powder, aggregate, cement, and polymer additives. The tests performed on raw materials include determining purity levels, particle size distribution, setting time of cement (Vicat test), and reactivity.

2. Quality Control of the Production Process

During various stages of production, the quality control unit focuses on identifying and controlling the quality of the product being manufactured. The production process for autoclaved aerated concrete (AAC) includes the following steps:

  • Production of Sand Slurry
  • the Raw Materials and Pouring them into Molds
  • Keeping the Mold in the Rising Chamber to Produce a Green Cake
  • Cutting the Green Cake into Desired Dimensions
  • Curing the Green Cake in the Autoclave
  • Packaging

The production process for products in the dry mortar unit includes the following steps:

  • Weighing and Measuring
  • Mixing the Raw Materials Uniformly
  • Packaging

3. Quality Control of the Final Product

After the visual inspection of the produced product and to ensure that it complies with standard specifications, the following tests are conducted on the autoclaved aerated concrete (AAC). Once confirmed, the product is packaged, labeled, and delivered to the warehouse for shipment to customers.

In addition to the mandatory tests specified by the Iranian national standards, all defined international tests for autoclaved aerated concrete (AAC) are performed, and the information is recorded. These data are available upon request from customers.
