Mortar Volume Formula:
From: | To: |
Definition: This calculator estimates the amount of mortar needed for UK brickwork based on wall area, mortar thickness, mix ratio, and mortar yield.
Purpose: It helps builders and DIYers determine how many bags of mortar are required for bricklaying projects.
The calculator uses the formula:
Where:
Explanation: The wall area is multiplied by mortar thickness (converted to meters) and ratio, then divided by the yield per bag.
Details: Accurate mortar estimation ensures proper bonding of bricks, structural integrity, and cost-effective material purchasing.
Tips: Enter the wall area in m², mortar thickness (default 10mm), ratio (default 1.0), and yield (default 0.011 m³/bag). All values must be > 0.
Q1: What's a typical mortar thickness for UK brickwork?
A: Standard mortar joints are typically 10mm thick in the UK, but can range from 6-12mm depending on the project.
Q2: What does the mortar ratio represent?
A: The ratio accounts for mortar composition (e.g., 1:5 cement:sand would use ratio 1.2). Default is 1.0 for standard mixes.
Q3: What's the typical yield for a mortar bag?
A: A standard 25kg bag of mortar typically yields about 0.011 m³ when mixed, but check manufacturer specifications.
Q4: How do I calculate wall area?
A: Multiply wall length by height. For multiple walls, calculate each separately and sum the areas.
Q5: Does this include waste or overage?
A: No, consider adding 5-10% to the calculated amount for project contingencies and wastage.
