How Cement Requirement Is Calculated
This calculator finds the total volume of your slab or structure, then applies your selected mix ratio to determine how much cement, by weight and standard 50kg bags, is required for the job.
Formula Used
Volume = Length × Width × Thickness
Cement Bags = (Volume × Cement Ratio Part / Total Ratio Parts) × 1440 ÷ 50
