The height change results in both test methods are expressed in terms of percentage increase or decrease of the original specimen height.
An exception is made when the options described in the section on test conditions are exercised. Sieve size is identified by its standard designation in Specification E These test methods cover procedures for assessing the adhesion of coating films to metallic substrates by applying and removing pressure-s The degree of restraint varies with the mixture viscosity and degree of hardening.
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. The height change of a 3-inch mm -diameter by 6-inch mm -tall cylindrical specimen was measured in accordance with ASTM C Some values have only SI units because the inch-pound equivalents are not used in practice.
I married on 30 th June now having one b 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. Testing of shrinkage for concrete – grout.
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.
Combining values from the two cc1090 may result in non-conformance with the standard. The laser approach has been compared with the original setup, and similar results were obtained.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This thickness was then added to the four-reading initial measurement. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size.
Two cylindrical specimens with the same dimensions as those used for the ASTM C test method were prepared 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.
ASTM C Standard
After removal, the thickness of the glass plate was measured with a caliper at the points of contact between the glass plate and the micrometer. Link to Active This link will always route to the current Active version 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 Newer Post Older Post Home. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the atsm. For cementitious grouts, saturate the surface up to SSD. The glass plate was removed from the top aetm the test specimen after 24 h.
