ASTM C1437-20 PDF Download

ASTM C1437-20 is a standard test method used to determine the flow of hydraulic cement mortars. It can also be used for mortars containing cementitious materials other than hydraulic cements. Flow is not typically included in hydraulic cement specifications, but it is commonly used in standard tests that require the mortar to have a specified flow level based on its water content.

This standard provides guidelines for conducting the flow test and specifies the equipment and procedures to be followed. The flow of the mortar is measured and reported in millimeters. It is important to note that the explanatory material provided in notes and footnotes throughout the standard are not considered as requirements.
