Enter the parts cement and the parts sand into the Calculator. The calculator will evaluate the Cement Sand Ratio. 

Cement to Sand Ratio Formula

CSR = C / S


  • CSR is the Cement to Sand Ratio ()
  • C is the parts cement
  • S is the parts sand

To calculate Cement Sand Ratio, divide the parts of cement by the parts of sand.

How to Calculate Cement Sand Ratio?

The following steps outline how to calculate the Cement Sand Ratio.

  1. First, determine the parts cement. 
  2. Next, determine the parts sand. 
  3. Next, gather the formula from above = CSR = C / S.
  4. Finally, calculate the Cement Sand Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.
