Concrete Block Calculator

Formulas Used:

Step 1: Wall Volume
Formula: Length × Width × Wall Thickness

Step 2: Brick Volume
Formula: Brick Length × Brick Width × Brick Height

Step 3: Brick with Mortar Volume
Formula: (Brick Length + 0.015) × (Brick Width + 0.015) × (Brick Height + 0.015)
The thickness of the mortar is 1.5cm

Step 4: Number of Bricks
Formula: Wall Volume / Brick with Mortar Volume

Step 5: Total Brick Volume
Formula: Number of Bricks × Brick Volume

Step 6: Mortar Volume
Formula: Wall Volume - Total Brick Volume

Step 7: Total Mortar Volume with Waste
Formula: Mortar Volume × 1.15

Step 8: Dry Mortar Volume
Formula: Total Mortar Volume with Waste × 1.25

Step 9: Cement Volume
Formula: (Cement Ratio / (Cement Ratio + Sand Ratio)) × Dry Mortar Volume

Step 10: Number of Cement Bags
Formula: Cement Volume / 0.035

Step 11: Sand Volume
Formula: (Sand Ratio / (Cement Ratio + Sand Ratio)) × Dry Mortar Volume

Step 12: Sand Weight
Formula: Sand Volume × 1550 kg
