It is particularly applicable to grouting, d827, and form-filling operations where the objective is to completely fill a cavity or other defined space with a freshly mixed cementitious mixture that will continue to fill the same space at time of hardening.

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.
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. If you need more info or have any questions, please note the Lab ID number and contact us at: Print and complete the following order form.
MSDS must accompany all samples submitted.
Historical Version s – view previous versions of standard. Instructions Submit all necessary materials to perform test including mixing instructions, mix design. These notes and footnotes shall not be considered as requirements of the test method.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. It would be appropriate to use this test method as a basis for prescribing mixtures xstm restricted or specified volume change before the mixture becomes hard.
Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.
These include shrinkage or expansion due to hydration, settlement, evaporation, and other physical and chemical effects. If you need more info or have any questions, please note the Lab ID number and contact us at:. Order Form 2 Email complete form to contact listed below.

Results Produced All height change measurements will be reported as percent change over time. Contact Mike Morrison for additional information. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Combining values from the c8277 systems may result in non-conformance with the standard. Further, the degree of restraint to which the specimen is subjected varies with the viscosity c872 degree of hardening of the mixture.
