Production line and factory setup overview
A strategic autoclaved aerated concrete plant producing defined lightweight wall blocks from prepared silica sand or fly ash, lime, cement, gypsum, water and controlled aluminium paste through milling, batching, casting, pre-curing, wire cutting, autoclave curing, packing and strength/density release. It is not a simple concrete-block machine.
Recommended lowest-entry line configuration Screen one 100,000-200,000 m3/year block size family only after proving silica/lime chemistry, steam generation, autoclave safety, water, laboratory control, covered curing/packing and contractor off-take.
Production process and implementation sequence
- Silica preparation and slurry milling
- Lime/cement/gypsum dosing and aluminium addition
- Casting and controlled pre-curing
- Wire cutting and green-cake handling
- Autoclave pressure curing
- Packing, density/strength testing and dispatch
Products, capacity and market fit
- Lightweight masonry can reduce wall weight and thermal load.
- AAC quality depends on raw-material chemistry, density and controlled autoclave curing.
- Steam, pressure-vessel compliance and buyer acceptance are non-negotiable.
- AAC lightweight blocks - Density, compressive strength, dimensions, moisture, thermal performance and edge quality - Afghan contractors, housing developers and block distributors
