Calculate the exact amounts of cement, sand, and gravel needed for your concrete project

Understanding Concrete Mix Ratios

The concrete mix ratio determines the strength and durability of your concrete. The ratio represents the proportions of:

  • 🏗️ Cement - The binding agent
  • 🏖️ Sand - Fine aggregate
  • 🪨 Gravel - Coarse aggregate
  • 💧 Water - Activates the cement

Common applications for different mix ratios:

  • • 1:5:10 - Basic concrete slabs and footings
  • • 1:3:6 - Driveways and patios
  • • 1:2:4 - Structural concrete
  • • 1:1:2 - High-strength applications
