Concrete quantity

Wet concrete0 m³ · 0 CFT
Dry volume (× 1.54)0 m³
Cement (50 kg bags)0 bags
Sand0 m³ · 0 CFT
Aggregate (20 mm)0 m³ · 0 CFT
Water (w/c 0.5)0 litres
How it is worked out
  1. 1.Wet volume = 0 × 0 × 0 m = 0 m³
  2. 2.Dry volume = wet × 1.54 (standard practice) = 0 m³
  3. 3.M20 M20 (1 : 1.5 : 3) → cement 0 bags · sand 0 m³ · aggregate 0 m³
  4. 4.Water ≈ 0.5 × cement content = 0 litres (about 0 drums)

Brickwork quantity

Brickwork volume0 m³ · 0 CFT
Bricks (incl. 5% wastage)0 nos
Mortar (dry, 1:6)0 m³
Cement0 bags
Sand0 m³ · 0 CFT
How it is worked out
  1. 1.Net area = (0 × 0) × 1 wall(s) = 0 m²
  2. 2.Volume = 0 m² × 230 mm = 0 m³
  3. 3.Bricks = 0 m³ × 500/m³ (modular, with mortar joints) + 5% wastage = 0 nos
  4. 4.Mortar ≈ 25% of brickwork volume = 0 m³ wet → × 1.33 dry = 0 m³
  5. 5.Mortar 1:6 → cement 0 bags · sand 0 m³ (0 CFT)

Blockwork quantity

Blockwork volume0 m³ · 0 CFT
Concrete hollow block 400 × 200 × 200 blocks (incl. 3% wastage)0 nos
Mortar (dry, 1:6)0 m³
Cement0 bags
Sand0 m³ · 0 CFT
How it is worked out
  1. 1.Net area = (0 × 0) × 1 wall(s) = 0 m²
  2. 2.Concrete hollow block 400 × 200 × 200 mm blocks with 10 mm joints → 11.61 blocks per m² (0.41 × 0.21 m face each)
  3. 3.Blocks = 0 m² × 11.61/m² + 3% wastage = 0 nos
  4. 4.Volume = 0 m² × 200 mm = 0 m³
  5. 5.Mortar = blockwork volume − block volume = 0 m³ wet → × 1.33 dry = 0 m³
  6. 6.Mortar 1:6 → cement 0 bags · sand 0 m³ (0 CFT)

Sand, aggregate & filling

Fill volume (compacted)0 m³ · 0 CFT · 0 brass
Order loose (+7%)0 m³ · 0 CFT
Approximate weight0 tonnes
Tractor loads (~100 CFT)0
Tipper loads (~400 CFT)0
How it is worked out
  1. 1.Volume = 0 × 0 × 0 m = 0 m³ (compacted in place)
  2. 2.Order ≈ 7% extra loose = 0 m³ = 0 CFT
  3. 3.River sand ≈ 1600 kg/m³ → about 0 tonnes
