Calculating the required number of standard construction blocks:
Block producers are often asked how many standard blocks are needed for a project. The table below provides a very fast, simple and accurate way to find the answer.

MEASUREMENTS FOR 8X8X16 STANDARD FACE BLOCK
|
| Length |
To calculate the number of construction blocks by a specific length:
Multiply the length by .75
Example: 140 ft. x .75 = 105 blocks (includes the mortar joints)
|
| Height |
To calculate the number of rows of construction blocks by a specific height:
Multiply the height by 1.5
Example: 8 ft. x 1.5 = 12 rows (includes the mortar joints)
|
| Area |
To calculate the number of construction blocks by a specific area:
Multiply by 1.125
Example: 160 Sq. Ft. x 1.125 = 180 blocks (includes the mortar joint)
|
Mortar Quantities: 60 blocks to One(1)-80lb Bag of Mortar
Premix Quantities: 15 blocks to One(1)-80lb Bag of Premix
Mortar-Sand Quantities: Eight(8)-80lb Bags of Mortar Per/One(1) Yard of Mason Sand
Add to Block Amount: 5% to 10% should be added to all quantities for breakage, spillage and errors.
Concrete Volume Calculator
|
|
To use the Concrete Volume Calculator, simply
enter the width, length, and thickness of your pour, click on whether you are measuring
the thickness in feet or inches, then click on the Calculate button. The
calculator will estimate the number of cubic yards of concrete that will be required.

Block Wall Calculator
|
|
To use the Block Wall Calculator, simply enter the height and length of the wall, click on whether you are filling an 8-inch or 12-inch wall, then click on the Calculate button. The calculator will estimate the number of cubic yards that will be required. Note that this is an estimate. There is significant variation in fill space among different blocks. This calculator assumes the use of double open-ended bond beam (lintel) blocks.

Column Calculator
|
|
To use the Concrete Column Calculator, simply enter the height and diameter of the column, and click on the Calculate button. The calculator will display the number of cubic yards required.
