Metric Concrete Self Mix with Moisture Correction
Calculate the material needed to mix concrete based on a mix ratio for pouring a slab. Includes option for moisture correction of aggregate's weights and the adjusted amount of water needed in the mix.
The Calculation
- enter your mix ratio's
- cement to water ratio
- length of slab (metres)
- width of slab (metres)
- depth of slab (millimetres)
- absorption of fine aggregate (%)
- total moisture content in fine aggregate (%)
- absorption of course aggregate (%)
- total moisture content in course aggregate (%)
Results
- volume of concrete needed in cubic metres
- cement volume and weight (cubic metres and kilograms)
- volume and weight of the fine aggregate (cubic metres and kilograms)
- volume and weight of the course aggregate (cubic metres and kilograms)
- water in litres and kilograms
- total weight of concrete mix (kilograms)
- adjusted weight of fine aggregate (kilograms)
- adjusted weight of fine aggregate (kilograms)
- adjusted amount of water needed (kilograms and litres)
Relationship between the compressible strength of concrete and the water to cement ratio.
Ratios for non-air-entrained concrete vary between 0.41 for a 28-day compressible strength of 6000 lb/in 2 (41 MPa) and 0.82 for 2000 lb/in 2 (14 MPa).
