Concrete Evaporation Rate Calculator

Concrete evaporation rate is the rate at which water evaporates from freshly poured concrete. It is influenced by factors like temperature, humidity, wind speed, and concrete mix design. Monitoring evaporation is crucial to prevent premature drying and cracking. Evaporation rates can vary widely depending on environmental conditions and need to be carefully managed during concrete curing.
