This test method measures the ability of a grout mixture to retain its mixing water.

It is used for qualifying grout fluidifiers to be used in the production of PA concrete.

It may be used to compare the effects of various admixtures or materials combinations on the water retentivity properties of any cement-water grout.

1. Scope

1.1 This test method covers the procedure for determining the water retentivity of freshly mixed hydraulic cement grout mixtures for preplaced-aggregate (PA) concrete.

1.2 The values stated in SI units are to be regarded as the standard. The values given 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
