The standard ASTM C a “Change in Height at Early Ages of Cylindrical Specimens from Cementitious Mixtures”  describes a method. ASTM C Standard Test Method for Change in Height at Early Ages of Cylindrical Specimens from Cementitious Mixtures. Lab ID: Use This test is used. ASTM A/AM Steel, Sheet and Strip, Heavy-Thickness Coils, Hot- Rolled, Carbon, Commercial, Drawing, Structural, High-Strength Low-Alloy.
These notes and footnotes shall not be considered as requirements of the test method.
Use This test is used to determine the change in height of a 3×6-in cylinder from the time of casting until final set is reached. Print and complete the following order form. It is the responsibility of cc827 user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Further, the degree of restraint to which the specimen is subjected varies with the viscosity and degree of hardening of the mixture. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Order Form 2 Email sstm form to contact listed below. Contact Mike Morrison for additional information. Instructions Submit all necessary materials to perform test including mixing instructions, mix design.

It is particularly applicable to grouting, patching, and form-filling operations where the objective is to completely fill a cavity or other defined space with a freshly mixed cementitious atm that will continue to fill the same space at time of hardening. Historical Version s – view previous versions of standard.
However, the specimen used in this test method is not completely unrestrained so that the measurements are primarily useful for comparative purposes rather than as absolute values. Results Produced All height change measurements will be reported c872 percent change over time. The maximum change in height will be reported, maximum decrease, maximum increase, change in height at set time and change in height at conclusion of test.
These include shrinkage or expansion due to hydration, settlement, evaporation, and other physical and chemical effects.
It would be appropriate to use this test method as a basis for prescribing mixtures having restricted or specified volume change before the mixture becomes hard.
