A Block Mortar Calculator helps estimate the amount of mortar required for laying blocks or bricks, based on the number of blocks and the mortar coverage per unit. It calculates the mortar volume needed to fill joints between blocks for a specific project.
Step 1: Determine the total number of blocks
Total number of blocks = Length of the wall × Height of the wall ÷ Area of one block
Step 2: Calculate mortar required per block
Mortar required per block is typically measured in cubic inches or cubic feet. This depends on the size of the block and the thickness of the mortar joints. For example, if the mortar joint thickness is around 3/8 inch, you might use a specific standard.
Step 3: Total mortar needed
Total mortar required = Number of blocks × Mortar required per block
Step 4: Convert mortar volume to bags
Mortar coverage per bag is usually given (like 10 square feet of wall per bag of mortar). If you know the total mortar volume and the coverage per bag, you can calculate:
