Masonry Unit & Mortar Volume Formula
N_{bricks} = frac{V_{net}}{(L_b + j)(W_b + j)(H_b + j)}; quad V_{dry_mortar} = 1.33 times (V_{wall} - N times V_{actual})
Engineering Specifications & Method of Calculation
Calculate required masonry bricks and mortar for single or double leaf partition and structural walls. Includes exact opening deductions for doors and windows plus mortar joint calculations.
Standard Masonry Calculations
Bricks are laid with standard 10mm (3/8 inch) cement-sand mortar joints. Deduct opening areas for doors and windows before calculating net wall volume. Dry mortar requires a 1.33 factor to account for joint filling and shrinkage.
Frequently Asked Questions
What is the standard size of a modular brick?
Standard modular bricks measure 190 mm x 90 mm x 90 mm. With 10 mm mortar joints, the nominal size becomes 200 mm x 100 mm x 100 mm.
How many modular bricks are needed per cubic meter?
Exactly 500 nominal modular bricks are required per cubic meter of masonry work.
