ASTM C937-16

Standard Specification for Grout Fluidifier for Preplaced-Aggregate Concrete

ABSTRACT
This specification covers fluidifier for grout used for preplaced-aggregate (PA) concrete. Grout ingredients shall conform to the specified requirements for Portland cement, pozzolan, and fine aggregate composition. The fluidifier, tested in grout shall conform to the specified values of reduction in mixing water, expansion, bleeding, increase in water retentivity, initial and final setting time, and compressive strength.
SCOPE
1.1 This specification covers fluidifier for grout used for preplaced-aggregate (PA) concrete.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 The following precautionary caveat pertains only to the test method portion, Section 8, of this standard: 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.
