Aircrete Calculator

What is Aircrete?

Aircrete, also known as foam concrete or cellular concrete, is a lightweight building material made from cement, water, and stable foam. It offers excellent thermal insulation, fire resistance, and is much lighter than traditional concrete blocks, making it ideal for walls, domes, and various construction projects.

How to Use This Aircrete Calculator

• Wall dimensions: Enter the length and height of your wall in feet
• Block size: Enter your aircrete block dimensions in inches (standard US sizes: 24"×8"×8" or 24"×8"×4")
• Price per block: Enter the cost per block in USD
• Mortar joint: Specify the mortar joint thickness (typically 3/8" or 0.375")
• Waste factor: Add 5-10% for breakage and cuts

Why Choose Aircrete?

• ✅ Lightweight — Up to 80% lighter than traditional concrete
• ✅ Energy efficient — Excellent thermal insulation properties
• ✅ Fire resistant — Non-combustible material
• ✅ Easy to work with — Can be cut with standard woodworking tools
• ✅ Cost-effective — Lower material and labor costs
• ✅ Sustainable — Uses less cement and reduces carbon footprint

Aircrete vs Traditional Concrete Blocks

• Weight: Aircrete blocks weigh 25-40 lbs/ft³ vs concrete at 140 lbs/ft³
• Thermal insulation: Aircrete R-value ~10 for 8" block vs concrete R-value ~1-2
• Workability: Aircrete cuts easily with hand saws; concrete requires masonry tools
• Cost: Aircrete typically $2-5 per block; concrete blocks $1-3 per block

Aircrete Mix Proportions (for reference)

• Standard mix: 1 part cement : 1-2 parts sand : water : foam
• Typical density: 40-80 lbs/ft³ (640-1280 kg/m³)
• Compressive strength: 300-1,500 psi depending on density
• Curing time: 7-28 days for full strength

Frequently Asked Questions

• How many aircrete blocks do I need per square foot? — For standard 24"×8" blocks, you need about 0.75 blocks per square foot (including joints).
• What mortar is used for aircrete? — Use thin-bed mortar specifically formulated for aircrete, or Type S mortar with a bonding agent.
• Can aircrete be used for load-bearing walls? — Yes, aircrete blocks can be used for load-bearing walls with proper reinforcement and engineering.
• How much does aircrete cost in the US? — Prices typically range from $2 to $5 per standard 24"×8"×8" block, depending on supplier and quantity.
• Is aircrete waterproof? — Aircrete is porous and should be sealed or plastered for exterior applications.
