ASTM C953-17
(Test Method)Standard Test Method for Time of Setting of Grouts for Preplaced-Aggregate Concrete in the Laboratory
Standard Test Method for Time of Setting of Grouts for Preplaced-Aggregate Concrete in the Laboratory
SIGNIFICANCE AND USE
5.1 This test method determines the time of setting of grout mixed to the fluid consistency required for its use in PA concrete.
5.2 The time of setting is also useful in determining the acceptability of components of grout that must be mixed to the fluid consistency required for production of PA concrete.
SCOPE
1.1 This method covers the determination test of time of setting of hydraulic cement grout mixtures used in preplaced-aggregate (PA) concrete using the Vicat apparatus.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
