It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Two cylindrical specimens with the same dimensions as those used for the ASTM C test method were c090 in which the change in height was measured at four points on the top surface of the specimens using a micrometer in accordance with ASTM C at 1, 3, 7, 14, and 28 d see figure Historical Version s – view previous versions of standard.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Some values have only SI units because the inch-pound equivalents are not used in practice.
ASTM C Standard
In both test methods, there is always a certain degree of friction between the specimen’s sides and the inner surface of the metallic mold. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size.
I married on 30 th June now having one b Link to Active This f1090 will always route to the current Active version of the standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
This approach provided more simplicity in the execution of the test, rather than using a projector lamp, magnifying lens, and indicator charts as described in ASTM C see figure The height c109 of a 3-inch mm -diameter by 6-inch mm -tall cylindrical specimen was measured in accordance with ASTM C The degree of restraint varies with the mixture viscosity and degree of hardening. For cementitious grouts, saturate the surface up to SSD.
The laser approach has been compared with the original setup, and similar results were obtained.
Axtm size is identified by its standard designation in Specification E Testing of shrinkage for concrete – grout. The height change results in both test methods are expressed in terms of percentage increase or decrease of the original specimen height. Though not recommended by the ASTM standards, and in order to provide the lowest friction possible, an acetate sheet was used in between the test specimen and the mold.
After removal, the thickness of the glass plate was measured with a caliper at the points of contact between the glass c10900 and the micrometer. This thickness was then added to the four-reading initial measurement.

The glass plate was removed from the top of the test specimen after 24 h. These test methods cover procedures for assessing the adhesion of coating films to metallic substrates by applying and removing pressure-s Combining values from the two systems may result in non-conformance with the standard.
An exception is made when the options described in the section on test conditions are exercised.
