ASTM C827 – Standard Test Method for Change in Height at Early Ages of Cylindrical Specimens of Cementitious Mixtures
This test method covers the determination of change in height of cylindrical specimens from the time of molding until the mixture is hard.
This test method covers height change measurements at early ages for cementitious mixtures of paste, grout, mortar, and concrete.
This test method is intended for determination of changes in height that occur from the time of placement until the specimen is fully hard. These include shrinkage or expansion due to hydration, settlement, evaporation, and other physical and chemical effects.
