Concrete and cement bags calculator.
Estimate dry materials, cement bags, sand and aggregate from volume and mix ratio.
Concrete and cement bags inputs
Material estimate only. Mix design, strength grade, moisture correction, aggregate grading and structural requirements need qualified engineering.
Method: Wet concrete volume is multiplied by the entered dry-volume factor, then divided among cement, sand and aggregate in the entered ratio.
Inputs used: Wet concrete volume = 1 m³; Cement ratio = 1 parts; Fine sand ratio = 1.5 parts; Coarse aggregate ratio = 3 parts; Wet-to-dry volume factor = 1.54 factor
Assumptions: Site and equipment inputs are planning assumptions supplied by the user or displayed by the calculator.
Scope and warnings: Material estimate only. Mix design, strength grade, moisture correction, aggregate grading and structural requirements need qualified engineering. Obtain site-specific engineering and equipment checks before purchase or installation.
How this concrete and cement bags calculator works
Wet concrete volume is multiplied by the entered dry-volume factor, then divided among cement, sand and aggregate in the entered ratio.
A worked example
One cubic metre at 1:1.5:3 has 5.5 total dry-material parts.
Is this a concrete mix design?
No. Strength grade, moisture correction, aggregate grading and structural specification need qualified engineering.
Calculations run on your device. Review your results before exporting or sharing them.
Keep volume and strength separate
The dry-volume and ratio calculation estimates ingredients from entered wet volume. It does not establish whether a mix meets M15, M20 or another structural requirement.
Use an engineer and the project specification for strength, reinforcement, aggregate, water and curing. Correct material quantities for actual batching and moisture conditions.
