What it’s Made From
Cement
The primary binding material, providing strength and durability to the block.
Lime
Used to enhance the block's strength and stability.
Sand
Fine aggregates that provide bulk and structural integrity.
Water
Essential for the hydration process, allowing the cement and lime to bind the sand.
Aluminium Powder
Reacts with lime to form tiny air bubbles, giving the block its lightweight and insulating properties.
Variations
High-Density AAC Block
Description: Denser and stronger, providing enhanced load-bearing capacity.
Applications: Suitable for load-bearing walls and structural elements.
Low-Density AAC Block
Description: Lighter and more insulating, offering superior thermal properties.
Applications: Ideal for non-load-bearing walls and partitions where insulation is key.
Fire-Resistant AAC Block
Description: Enhanced fire resistance, providing additional safety in construction.
Applications: Used in fire-rated walls and partitions to improve building safety.
Installation
Tools Required
Trowel | Spirit level | Tape measure | Rubber mallet | Hand saw
Materials Required
Aerated concrete blocks | Thin-bed mortar | Water | Reinforcement mesh (if needed)
Step-by-Step Guide:
Preparation: Clear the site and lay out the foundation lines.
Mix Mortar: Use a thin-bed mortar mix designed for AAC blocks.
Lay First Course: Start with a mortar bed, place the first row of blocks, and check alignment.
Cut to Size: Use a hand saw to cut blocks to the required size.
Build Up: Continue laying blocks with thin-bed mortar, ensuring each layer is level.
Reinforcement: Add reinforcement mesh if required for additional strength.
Final Checks: Ensure all blocks are properly aligned and joints are filled with mortar.

Purchasing Quantities
Single Units
Perfect for small projects, repairs, or when only a few blocks are needed.
Pallets
Typically sold in bulk, with each pallet containing around 50 to 100 blocks. This option is suitable for medium to large construction projects.
Bundles
Smaller quantities than pallets, often sold in bundles of 10, 20, or 30 blocks, suitable for minor projects or additions.
Environmental Impact
Sustainability Considerations
Production involves lower energy consumption compared to traditional concrete blocks. AAC blocks are recyclable and reduce the overall environmental footprint of construction projects.
Eco-friendly Alternatives
Using recycled materials or fly ash in the production process further enhances the environmental benefits of aerated concrete blocks.
Waste Reduction
Precise planning and ordering minimize waste. Surplus blocks can be crushed and recycled into new blocks.
Energy Efficiency
High thermal insulation properties significantly reduce heating and cooling costs, contributing to overall energy savings in buildings.
