ASTM C1090/C1090M-15 + Redline

1.1 This test method covers measurement of the changes in height of hydraulic-cement grout by the use of 75 by 150-mm [3 by 6-in.] cylinders, when the cylinders are protected so that the tendency to change in height does not include evaporation so as to cause drying, uptake of moisture, carbonation, or exposure to temperatures outside the range 23 ± 2.0°C [73 ± 3.5°F] or, optionally, to another specified temperature controlled within ±2.0°C [±3.5°F].
