EUROLAB laboratory provides testing and compliance services within the scope of ASTM C979 standard. The ASTM C979 standard covers the basic requirement for powdered colored and white pigments to be used as additives in concrete to produce integrated colored concrete. Where pigments are a component of a multicomponent mixture, this specification applies to the pigment component of the mixture.
This specification is not intended to determine the compatibility of pigments with other concrete additives unless they have been tested in combination for compatibility.
This specification does not include determination of pigment stability when using elevated temperature using low pressure (atmospheric) or high pressure (autoclave) steam to accelerate the curing process.
In addition to the tests that describe the pigments themselves, a limited number of tests on concrete are included to identify effects on setting times, air content and compressive strength. If more comprehensive information is required for a particular job, additional testing criteria and procedures should be agreed between the vendor and the user.
The maximum prescribed dosage rate of a pigment determined by substance shall be less than or equal to 10% by 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.
Cement (Type I or Type II), aggregates and additives shall be subjected to the following test methods: water wettability; alkali resistance; sulfate percentage; water solubility; atmospheric curing stability; light resistance; effects on concrete including preparation of mixes, making and curing, setting time, air content and compressive strength; and the color matching of the shipment.
Values stated in SI units should be accepted as standard. The inch-pound units in parentheses are for informational purposes only.
