Concrete

Concrete mix: cement, sand, aggregate, water

Inputs

Formulas

V_sec = V × k
Σ = c + s + g
V_ciment = V_sec × c/Σ ; M_ciment = V_ciment × ρc
V_sable = V_sec × s/Σ ; V_gravier = V_sec × g/Σ
Eau = M_ciment × E/C

Assumptions

  • Nominal volumetric mix method (e.g. 1:2:4). The 1.54 factor accounts for the volume reduction of dry materials once mixed.
  • Quantity estimate only: structural concrete must be designed by a mix-design study and the project specification.
  • Aggregates assumed dry; correct water for actual sand moisture.

These tools provide estimates and calculation aids. They are neither design calculations nor an engineering approval: any design or safety decision must be checked by a qualified professional against the applicable standards.
