ASTM C979/C979M − 10 Standard Specification for Pigments for Integrally Colored Concrete

ASTM C979/C979M − 10 Standard Specification for Pigments for Integrally Colored Concrete

Scope
1.1 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 4.7.

1.2 This specification does not include the determination of pigment stability when elevated temperature using

low pressure (atmospheric) or high-pressure (autoclave) steam is used to accelerate the curing process.

1.3 In addition to tests defining the pigments themselves, a limited number of tests on concrete are included to define the effects on setting times, air content, and compressive strength.

If more extensive information is required for a particular job, additional testing criteria and procedures should be agreed upon between the seller and user

Materials for Tests
7.1 Cement—For the atmospheric curing stability and the light resistance tests, using white cement is suggested.
