PCC Dimensions
ℹ️Typical: 75-100 mm (foundation blinding), 100-125 mm (flooring / floor base)
Common PCC thickness:
Cost
For a 12.00 m² footprint, you need approximately 1.26 m³ (44.5 cft) of PCC concrete — 5.6 cement bags.
PCC Concrete
Wet volume (before wastage): 1.200 m³
Dry volume: 1.848 m³
Final quantity (with wastage): 1.26 m³ (44.5 cft)
Materials
Cement: 5.6 bags (280 kg)
Sand: 0.58 m³ (20.6 cft)
Aggregate: 1.16 m³ (41.1 cft)
Assumptions Used
Dry volume factor: 1.54 | Cement bag: 50 kg / 0.0347 m³ | PCC is non-reinforced — no steel, and no shuttering (cast directly against the excavation or a prepared subgrade, not panel formwork).

Complete PCC material estimate
This page gives the full combined result for a Plain Cement Concrete (PCC) layer — wet and dry volume, cement bags, sand, and aggregate, with dry volume correction and wastage — from one set of length, width, thickness, and mix ratio inputs.
It's the same calculator behind every other PCC variant on this site, just without a specific scenario pre-selected — useful for a general PCC estimate before finalizing the exact layer with your site engineer.
- PCC is non-reinforced — used for blinding, levelling courses, and hard standing, not structural elements.
- Dry volume correction (×1.54) is applied before splitting into cement, sand, and aggregate.
- An optional cost estimate can be turned on from the same form.
How Is PCC Quantity Calculated?
PCC quantity is calculated from wet concrete volume, a dry-volume correction factor, and cement-sand-aggregate mix ratio distribution, then an optional cost estimate on top.
Step 1 — PCC Volume
Wet Volume = Length × Width × Thickness
Dry Volume = Wet Volume × 1.54
Dry volume accounts for the voids between aggregate particles that disappear once the concrete is mixed and compacted. The dry volume is split into cement, sand, and aggregate using the selected mix ratio, and wastage is applied once to the final quantities.
Step 2 — Cement Bags
Cement Volume = Dry Volume × (Cement Ratio Part ÷ Total Ratio Parts)
Cement Bags = Cement Volume ÷ 0.0347 m³/bag (50 kg bags)
Sand and aggregate are split the same way, using their own ratio parts. One standard cement bag (50 kg) occupies approximately 0.0347 m³.
Step 3 — Final Quantity with Wastage
Final Wet Volume = Wet Volume × (1 + Wastage %)
This final wet volume (and the wastage-adjusted cement/sand/aggregate figures) is the practical quantity to order or batch on site — shown separately from the theoretical pre-wastage volume.
Worked Example
This example walks through your current inputs above, using the same steps as the Formula section.
Input Values Used
| Input | Value | Why it is used |
|---|---|---|
| Length × width × thickness | 4m × 3m × 100mm | Sets the wet concrete volume |
| Mix ratio / wastage | 1:3:6, 5% wastage | Splits dry volume into cement/sand/aggregate and adds a buffer for site losses |
Step 1 — Volume
| Calculation | Substitution | Result |
|---|---|---|
| Wet volume | 4m × 3m × 100mm | 1.200 m³ |
| Dry volume | 1.200 × 1.54 | 1.848 m³ |
| With 5% wastage | 1.200 × 1.05 | 1.260 m³ (44.5 cft) |
Step 2 — Materials
| Material | Quantity |
|---|---|
| Cement | 5.6 bags (280 kg) |
| Sand | 0.58 m³ (20.6 cft) |
| Aggregate | 1.16 m³ (41.1 cft) |
Therefore, approximately 1.26 m³ (44.5 cft) of PCC concrete should be ordered or batched for this layer, needing 5.6 cement bags, while sand and aggregate are estimated separately for site mixing.
