Standard Specification for Pigments for Integrally Colored Concrete
ABSTRACT
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 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. Cement (either Type I or Type II), aggregates, and admixtures materials shall be subjected to the following test methods: water wettability; alkali resistance; percentage of sulfates; water solubility; atmospheric curing stability; light resistance; effects on concrete, which include preparation of mixtures, making and curing, time of setting, air content, and compressive strength; and color match of shipment.
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 .
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.
1.4 The maximum prescribed dosage rate of a pigment, established in accordance with , shall be equal to or less than 10 mass % of cement. When a combination of pigments is used to produce the desired color and color intensity, the total dosage rate of all pigments combined shall not exceed any of the individual maximum dosage rates of the component pigments.
1.5 The values stated in SI units are to be regarded as the standard. The inch-pound units in parentheses are for information purposes only.
