American Society for Testing and Materials (ASTM). Current edition approved Jan. 1, 2005. Published January 2005. Originally approved in 1982. Last previous edition approved in 2004 as C 979–04. 5 p. This specification covers the basic requirement for colored and white pigments in powder form to be used as admixtures in concrete for the purpose of producing integrally colored concrete. Where the pigments are a constituent of a multicomponent admixture, this specification applies to the pigment constituent of the admixture. This specification is not intended to establish compatibility of pigments with any other concrete admixtures unless they are tested in combination in accordance with 3.7.
