Concrete & Mortar Bucket Calculator

Concrete & Mortar Bucket Calculator

Field-friendly · 20L buckets · Sarim brand

Inputs

Mix type Concrete Mortar Custom (volume ratio)

Preset ratios

Cement (bag size, kg)

Bucket size (L)

Cement bulk density (kg/m³)

Wastage/Contingency (%)

Rounding Round up to full buckets Round to 0.5 bucket No rounding

Custom ratio (Cement : Sand [: Stone]) — only if "Custom" selected

Results

Cement volume (per bag)– L

Per 1 bag ⇒ Sand– buckets

Per 1 bag ⇒ Stone– buckets

Material	Litres	Buckets

Notes: Uses volume-batching based on cement bag volume (bag kg & density). Default density 1440 kg/m³ ⇒ 50 kg ≈ 34.7 L (~1.7 buckets of 20 L). Wastage added to sand & stone by default.

How it works (quick)

1. Compute cement volume from bag size & bulk density.
2. For ratio C:S[:St], sand L = (S/C) × cement L; stone L = (St/C) × cement L.
3. Add wastage to sand & stone; convert litres → buckets by bucket size.
4. Apply rounding rule.
