Calculate the material needed to mix concrete based on a mix ratio with volume calculation for pouring a slab. Includes the option to use moisture correction of the aggregate's weights and the adjusted amount of water needed in the mix.

Calculator

1. enter your concrete mix ratio's
2. the cement to water ratio (c/w)
3. the length of the slab in feet
4. the width of the slab in feet
5. the depth of the slab in inches

The following are optional:

1. the effective absorption of fine aggregate in a percentage
2. total moisture content in fine aggregate in a percentage
3. the effective absorption of coarse aggregate in a percentage
4. total moisture content in coarse aggregate in a percentage

Results

1. volume of concrete needed in cubic feet and cubic yards
2. cement volume and weight in cubic feet and pounds
3. the volume and weight of the fine aggregate in cubic feet and pounds
4. the volume and weight of the course aggregate in cubic feet and pounds
5. the amount of water needed in US gallons, pounds and Imperial gallons
6. the combined weight of concrete mix in pounds
7. the adjusted weight of fine aggregate in pounds
8. the adjusted weight of coarse aggregate in pounds
9. the adjusted amount of water needed in pounds, US and Imperial gallons
