|Publication Date:||10 July 1998|
|ICS Code (Cement. Gypsum. Lime. Mortar):||91.100.10|
1.1 This is a laboratory test method that covers the determination of the time of setting of hydraulic-cement mortars containing additives for shotcrete for comparison with control mixes containing no additives or to compare the performance of shotcrete mixtures which contain additives that produce rapid setting or rapid stiffening of shotcrete.
1.2 The values stated in SI units (see IEEE/ASTM SI 10) are the standard.
1.3 This standard may involve hazardous materials, operations, and equipment. 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.
