ASTM C1141-06

Standard Specification for Admixtures for Shotcrete

ABSTRACT
This specification covers materials proposed for use as admixtures to be added to a Portland-cement shotcrete mixture for the purpose of altering the properties of the mixture. The material shall be classified as Type I (dry mix shotcrete, with Grades 1-9) and Type II (wet-mix shotcrete, with Grades 1-9). Each of the grades shall be further classified by identifying it accordingly as Class A (liquid) or Class B (non-liquid). Shotcrete admixtures shall conform to the requirements for the applicable type and grade. Samples shall be either grab or composite samples, as specified or required by this specification. The number of tests and retests to be performed on the specified materials shall be the number stipulated in the referenced standard.
SCOPE
1.1 This specification covers materials proposed for use as admixtures to be added to a portland-cement shotcrete mixture for the purpose of altering the properties of the mixture.
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.
1.2 The values stated in inch-pound units are to be regarded as the standard.
