(Test Method)Standard Test Method for Flow of Hydraulic Cement Mortar
Standard Test Method for Flow of Hydraulic Cement Mortar
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.
SCOPE
1.1 This test method covers the determination of flow of hydraulic cement mortars.
1.2 The values stated in SI units are to be regarded as the standard. Values in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.

7. Procedure
7.1 Determination of Flow:
7.1.1 Carefully wipe the flow table clean and dry, and place the flow mold at the center. Place a layer of mortar about 25 mm
(1 in.) in thickness in the mold and tamp 20 times with the tamper. The tamping pressure shall be just sufficient to ensure uniform
filling of the mold. Tamping should be uniformly distributed over the cross section of each layer. For the bottom layer this will
necessitate inclining the tamper slightly when tamping near the perimeter. Then fill the mold with mortar and tamp as specified
