|Publication Date:||10 May 1998|
|ICS Code (Concrete and concrete products):||91.100.30|
significance And Use:
This method is useful for determining the expansion and bleeding characteristics of freshly mixed fluid grout used in PA concrete.
1.1 This test method determines the amount of expansion and accumulation of bleed water at the surface of freshly mixed hydraulic-cement grout used in the production of preplaced-aggregate (PA) concrete.
1.2 It is for use with cement grout whether or not it includes fine aggregate or mineral admixtures or both.
1.3 The values stated in SI units are to be regarded as standard.
1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
