How this calculator works
Estimate cement, sand and aggregate from concrete volume and nominal mix proportions.
dry volume = wet volume × factor; constituents split by mix ratio

Estimate cement, sand and aggregate from concrete volume and nominal mix proportions.
The calculator uses the following core relationship:
Estimating note: Actual material quantities can vary with site conditions, detailing, product dimensions, installation method, and waste.
A cement calculator helps estimate cement quantities for concrete, mortar and construction projects.
Final quantities vary according to concrete or mortar mix design.
Construction tip: Always verify dimensions, material specifications and project conditions before ordering materials.
Estimate cement, sand and aggregate from concrete volume and nominal mix proportions.
The calculator uses inputs such as Concrete volume (m³), Dry-volume factor, Cement ratio, Sand ratio, and Aggregate ratio. Use values from your drawings, measurements, product data, or project specifications.
Use outputs such as Cement, Cement bags, Sand, and Aggregate for estimating and cross-checking. Before purchasing or construction, confirm the dimensions, units, waste factors, supplier packaging, and project specifications.
