3. Significance and Use
3.1 This test method is intended to be used to determine the flow of hydraulic cement mortars, and of mortars containing
cementitious materials other than hydraulic cements.
3.2 While flow is not usually included in hydraulic cement specifications, it is commonly used in standard tests that require the
mortar to have a water content that provides a specified flow level.
