Standard gauging cement hydration rate to streamline trial mixture phase

Source: ASTM International, West Conshohocken, Pa.

ASTM C1753, Practice for Evaluating Early Hydration of Hydraulic Cementitious Mixtures Using Thermal Measurements, will help concrete producers evaluate relative binder differences in paste, mortar and other mixture specimens. The forthcoming standard describes the apparatus and procedure for such evaluations, and will augment efforts to screen and proportion materials—lowering or eliminating costs associated with trial mixtures.
