AAC Block Calculator — blocks, m³ and adhesive for your wall
Enter the wall length, height and block thickness, deduct doors and windows, and get the number of AAC blocks, the volume in cubic metres, adhesive bags and pallets — based on ASLAN block specifications.
How the calculator works
- Block face size is 600 × 250 mm, so one square metre of wall takes about 6.67 blocks at any thickness.
- Volume (m³) = net wall area × block thickness.
- Thin-bed adhesive: 3 to 4 kg per m² of wall; one 25 kg bag covers about 6 to 8 m² of 200 mm blockwork.
- Pallets are based on the packing table for each grade and thickness.
