Steps Involved in Building a HouseSpike's Calculators

Imperial Concrete Self Mix with Moisture Correction

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.

Mixing Ratio's
Cement # Sand # Gravel #
Cement/Water Ratio #
Length of Slab ft
Width of Slab ft
Depth of Slab in
Absorption Fine Aggregate %
Moisture Content Fine Aggregate %
Absorption Course Aggregate %
Moisture Content Course Aggregate %
Volume of Concrete Needed ft³ yd³
Volume and Weight of Cement ft³ lbs
Volume and Weight of Fine Aggregate ft³ lbs
Volume and Weight of Course Aggregate ft³ lbs
Water US gal lbs
Water Imp gal
Total Weight of Mix lbs
Aggregates and Water after Moisture Correction
Adjusted Weight of Fine Aggregate lbs
Adjusted Weight of Course Aggregate lbs
Adjusted Amount of Water
lbs US gal Imp gal

The Calculation

  1. enter your mix ratio's
  2. cement to water ratio
  3. length of slab (feet)
  4. width of slab (feet)
  5. depth of slab (inches)
  6. absorption of fine aggregate (%)
  7. total moisture content in fine aggregate (%)
  8. absorption of course aggregate (%)
  9. total moisture content in course aggregate (%)


  1. volume of concrete needed in cubic feet and cubic yards
  2. cement volume and weight (cubic feet and pounds)
  3. volume and weight of the fine aggregate (cubic feet and pounds)
  4. volume and weight of the course aggregate (cubic feet and pounds)
  5. water needed in US gallons, pounds and Imperial gallons
  6. total weight of concrete mix (pounds)
  7. adjusted weight of fine aggregate (pounds)
  8. adjusted weight of fine aggregate (pounds)
  9. adjusted amount of water needed (pounds, US and Imperial gallons)
Relationship between the compressible strength of concrete and the water to cement ratio.
