Field-Cured vs. Standard-Cured Cylinders
How Curing Methods Affect High-Strength ConcreteASTM C31 is the standard that defines two different concrete curing conditions, standard curing and field curing. It is the standard that dictates the procedures for making and curing test cylinders and can become a problem when an engineer or purchaser argues that field-cured test cylinders must be the basis of acceptance for a project.

The results from standard-cured concrete break tests are primarily used for quality control and concrete acceptance.ASTM C31 section 10.2 defines…
