Common Indian AAC sizes (Length × Height × Thickness). Wall thickness follows the block — thicker blocks use more mortar per m².
▼Thin-bed jointing mortar is laid at 2–3 mm — far thinner than a 12 mm sand-cement bed. That's the whole point of AAC.
Supplied in one standard pack.
Extra for spillage, mixing loss & uneven courses.
Consumption is calculated from block geometry — bed and perpend joints at your chosen thickness — at roughly 25–30 kg of mortar per m³ of masonry for a 3 mm joint. A 40 kg bag of Block Jointing Mortar covers about 1.3–1.5 m³ of AAC blockwork. Actual usage varies with block flatness, workmanship and site conditions; always confirm against the product datasheet.
