Comment calculer le volume de Blocs de Béton
Pour calculer le nombre de blocs, divisez la surface du mur par la surface frontale d'un bloc, puis multipliez par 1,10.
Chaque sac de mortier couvre environ 25 à 35 blocs. Nous incluons la perte de 10% automatiquement.
Conseils de pros
1
Standard CMU blocks are 8"×8"×16" (height × width × length). Always include a 10% waste factor for cuts and breakage.
2
One bag of mortar mix (80 lb) covers approximately 25–35 standard CMU blocks.
3
For retaining walls over 2 feet tall, always consult a structural engineer — wall failure can be catastrophic.
Foire aux questions
What size is a standard cinder block?▼
A standard CMU (Concrete Masonry Unit) is 8 inches high × 8 inches wide × 16 inches long. When laid with a ⅜-inch mortar joint, the installed size becomes 8 × 8 × 16 inches nominal.
How many cinder blocks are in a pallet?▼
A standard pallet of 8×8×16 cinder blocks contains 108 blocks and weighs approximately 3,000 lbs. This covers roughly 96 square feet of wall at one block high.
How many bags of mortar do I need for cinder blocks?▼
One 80 lb bag of mortar mix will set approximately 25–35 standard CMU blocks, depending on joint thickness. Factor 1 bag per 30 blocks as a planning estimate.
What is the difference between cinder blocks and concrete blocks?▼
Cinder blocks (legacy term) historically used coal cinders as aggregate and were lighter but weaker. Modern CMU blocks use concrete aggregate. The terms are now used interchangeably, but today's blocks are all concrete masonry units.
