Masonry Calculators
Last updated .
Pick the unit first. Brick, AAC, and concrete block pages count the units and, where the page does it, the mortar around them. Mortar, sand and cement, plaster, and screed are the mixes and the coats, without a wall count.
A brick wall’s mortar on this site is the joint around the brick, not a solid box the size of the wall. One leaf has no joint through the thickness. Two leaves add one collar joint. The Pakistan page is that method for a 9 × 4.5 × 3 in brick, in 50 kg bags and cubic feet. The room page is four walls with a door and a window. Sand and cement is the masonry mix. The concrete pour for a slab is the concrete hub, even when the wall sits on that slab. Stone veneer is flats and outside corners, with a scratch coat and a setting bed. Segmental retaining-wall blocks stay on the sand hub.
