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.
