High-Efficient 20,000 m³/year AAC Block Manufacturing Plant Delivered to Cameroon
In 2025, we supplied and commissioned a 20,000 m³/year autoclaved aerated concrete (AAC) block manufacturing plant for a building materials company in Cameroon. This installation supports local production of lightweight AAC blocks to serve residential, commercial, and infrastructure construction projects in Douala, Yaoundé and other major urban centres. The plant was configured to suit Cameroon’s raw material availability, workforce conditions, and operational requirements, enabling stable production and consistent product quality.

Construction Market Conditions in Cameroon
The construction industry in Cameroon has experienced steady growth supported by urban expansion, residential development and infrastructure investments in cities such as Douala, Yaoundé and Bafoussam. Local builders and contractors seek modern building materials that support faster build times, improved thermal performance, and reduced labour requirements compared with traditional clay bricks or concrete blocks. AAC blocks meet these needs and offer a lightweight and energy‑efficient alternative.
Despite ongoing demand, imported AAC products have faced challenges such as fluctuating supply and higher costs due to import dependencies. Establishing local production provides an opportunity for building material suppliers and contractors to improve delivery times and control production quality.
Client Background and Project Motivation
The client is a Cameroonian construction materials supplier aiming to diversify from traditional block distribution toward in‑house manufacturing. Before this project, AAC blocks were either imported or sourced from distant suppliers, which affected lead times and increased costs. To gain a better market position and improve supply reliability, the client opted for a 20,000 m³/year AAC block plant tailored to local market demand.
Key objectives included:
- Establish local production capability for AAC blocks
- Improve product delivery timelines and consistency
- Align plant design with raw material availability in Cameroon
- Manage investment and operational costs through appropriate capacity selection
The chosen plant capacity provides a practical balance between production output and investment, allowing the client to serve local and regional projects effectively while maintaining flexibility for future growth.
AAC Block Production Process
The 20,000 m³/year Macchina per la produzione di blocchi AAC delivered to Cameroon was designed to cover the complete production workflow from raw material preparation to finished block handling.
Main Production Steps
Raw Material Storage & Batching
Cement, lime, gypsum and sand or fly ash are stored and measured precisely to maintain consistent mix ratios.
Slurry Mixing
Materials are blended into a homogeneous slurry with precise aluminium dosing to control aeration and ensure uniform block structure.
Casting & Pre‑Curing
The aerated slurry is poured into moulds and allowed to pre‑cure until it forms semi‑solid “green cakes.”
Demoulding & Cutting
Green cakes are demoulded and cut into standard block sizes with controlled dimensional accuracy.
Autoclave Curing
Blocks are loaded into autoclaves for steam curing under controlled temperature and pressure, developing strength and thermal properties.
Block Handling & Packing
Finished blocks are separated, stacked, and prepared for storage or delivery to construction sites.
This workflow ensures the production of blocks that meet performance expectations in varied applications.
Main Equipment Supplied
The AAC block manufacturing plant includes:
- Raw material batching and weighing systems
- Slurry mixing machines
- Casting moulds and tables
- Cutting machines for precise block sizing
- Autoclave chambers and steam systems
- Material handling and stacking equipment
Equipment is selected and configured to operate under local power standards and to support reliable production performance with minimal maintenance.
Installation and Training
The project was delivered on a turnkey basis with comprehensive support:
- Plant Installation: Guided assembly and alignment of equipment in the designated factory area
- Commissioning & Adjustment: Trial runs and fine‑tuning to ensure design capacity and output quality
- Operator Training: Practical training for local staff on equipment operation, safety procedures and basic maintenance
Hands‑on training ensures local operators can run the plant independently and confidently after handover.
Operational Results and Benefits
Following commissioning, the AAC block plant achieved stable production and delivered consistent block quality. The client now benefits from:
- Steady local supply of AAC blocks for construction projects across Cameroon
- Reduced dependence on imported products and external suppliers
- Improved production scheduling and delivery timelines
- Better control over product quality and consistency
AAC blocks produced by this plant are suitable for a variety of building needs, from residential housing to commercial and institutional structures.
Typical Applications of AAC Blocks
Blocks manufactured by this plant are appropriate for:
- Load‑bearing and non‑load‑bearing walls
- Partition walls and infill blocks
- Residential building projects
- Commercial and institutional building structures
AAC blocks deliver lighter weight, improved insulation, and ease of handling compared with traditional masonry units, supporting more efficient construction workflows.
