Evaporation Volume Calculator

Note: that wind speeds should be determined at 0.5m above the evaporation surface elevation.
  • Conditions that increase the possibility of cracking include low air temperature, high concrete temperature low humidity and high wind speed (ACI 305).
  • Formula for evaporation losses from concrete surfaces from Concrete International, Title No 95-M34, “Plastic Shrinkage Cracking and Evaporation Formulas” by Dr. Paul J. Uno of Australia.
