Evaporation Calculator

Note: that wind speeds should be determined at 0.5m above the evaporation surface elevation.
  1. Conditions that increase the possibility of cracking include low air temperature, high concrete temperature low humidity and high wind speed (ACI 305).
  2. 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.
