Portland Cement Mix Calculator

What is a Portland Cement Mix Calculator?

A “Portland Cement Mix Calculator” is a tool used to calculate the quantities of Portland cement, sand, and aggregate required to create a specific concrete mix based on a given cement-sand-aggregate ratio and the desired total volume of concrete.

Why is a Portland Cement Mix Calculator Used?

This calculator is used to accurately plan and budget for concrete construction projects.

It helps determine the right proportions of cement, sand, and aggregate to achieve the desired concrete mix strength and volume.

How to Use a Portland Cement Mix Calculator:

1. Enter the cement-sand-aggregate ratio in the format "Cement:Sand:Aggregate." For example, "1:2:3" indicates one part cement, two parts sand, and three parts aggregate.
2. Enter the total volume of concrete you need in cubic feet or cubic meters.
3. Click the "Calculate" button.
4. The calculator will display the quantities of cement, sand, and aggregate required in either cubic feet or cubic meters.

Example Calculation:

Suppose you want to make 1 cubic yard of concrete with a 1:2:4 ratio (1 part cement, 2 parts sand, 4 parts aggregate).

After entering the ratio and total volume as 1 cubic yard, the calculator will display the amounts needed:

• Cement: 0.117 cubic yards (or the equivalent in cubic meters)
• Sand: 0.233 cubic yards (or the equivalent in cubic meters)
• Aggregate: 0.467 cubic yards (or the equivalent in cubic meters).
