The screed calculator uses the following formula:
Volume = Area × (Thickness / 1000) m³
Dry Volume = Volume × 1.15 (shrinkage factor)
Cement Volume = Dry Volume × (1 / 4) for 1:3 mix
Sand Volume = Dry Volume × (3 / 4)
Cement Mass = Cement Volume × 1400 kg/m³
Sand Mass = Sand Volume × 1600 kg/m³
Water = Cement Mass × 0.5
Standard Mix: Typical screed uses 1:3 cement-to-sand ratio (by volume).
Shrinkage Factor: We use 1.15 to account for compaction and air voids during mixing.
