Field-Cured vs Standard-Cured Concrete Break Tests Giatec

02/06/2021  ASTM 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.
