Plastic shrinkage cracks occur when the surface of the concrete dries rapidly and shrinks before it can gain sufficient tensile strength to resist cracking.
When ambient conditions & temperatures combine to produce conditions that create a high evaporation rate; the chances of the surface drying and shrinkage cracks forming increases.
Using this tool, you can quickly calculate the evaporation rate based on
•concrete temperature
•air temperature
•relative humidity
•wind velocity
