    Conditions That Cause Surface Shrinkage and CrustingThe NomographKestrelIR ThermometersWhat If.?Surface CrustingCuring IssuesSurface Crusting and CrackingThere are several ambient conditions working together that contribute to cracking on the surface of fresh concrete: air temperature, wind speed, relative humidity, and direct sunlight. Surface crusting is a phenomenon involving excessive temperature differentials between freshly placed concrete and the temperature of the surface being heated by the sun. The temperature of the ground can have a contributing effect if it causes ready-mix temperatures to drop. Concrete mix ingredients such as the a
