About Cement Concrete Calculator

Cement Concrete Calculator — Calculate the exact quantity of cement bags, sand, and aggregate required for a specific volume of concrete based on standard mix proportions like M15 and M20.

How to use the Concrete Calculator

  1. Enter the total volume of concrete required (Length x Width x Thickness).
  2. Select the grade of concrete (M10, M15, M20, M25) depending on your structural needs.
  3. Click Calculate to determine the bags of cement, cubic feet of sand, and aggregate instantly.

FAQs

How many bags of concrete make a yard?
A cubic yard of concrete requires roughly 45 bags of 80lb pre-mixed concrete, or about 6 to 7 standard 50kg bags of cement if you are mixing it yourself with sand and aggregate.
How do I calculate concrete for a circular slab?
To calculate the volume of a circular slab, use the formula: Area = π × radius² × thickness. Once you have the total cubic volume, input it into the calculator above to find the material quantities.
