Concrete Water-Cement Ratio Calculator

Calculate water-to-cement ratio for target compressive strength. Abrams law: f_c = k₁/(k₂^(w/c)). ACI 318: w/c = 0.40 for 35 MPa, 0.45 for 28 MPa, 0.50 for 21 MPa. Maximum w/c for exposure conditions.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.
