ASTM WK35609

    New Test Method for Test Method for Consistency of Grouts

    (What is a Work Item?)

    Developed by Subcommittee: C09.41 | Committee C09 | Contact Staff Manager


    1. Scope

    1.1 This test method covers a procedure, used both in the laboratory and in the field, for determining the consistency of hydraulic cement grout of less than fluid consistency; however, the test method may also be used for other grouts and mortars that are of greater than plastic consistency. 1.2 It is for use with neat grout and with grouts containing aggregate all passing a 9.5-mm (3/8 in.) sieve. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4 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.

    Currently C1437 is modified by C1107 for determination of consistency of less than fluid consistency grouts and is usable only in the laboratory. This test method provides a simple, rapid, and economical means to evaluate the consistency of grout less than fluid consistency but more plastic than non-sagging consistency both in the laboratory and in the field based on the spread diameter of a specified volume and dimension of grout under the force of gravity. It is intended to better define grout consistency that is placed without additional vibrational energy.
