Anotace textu normy ASTM C979/C979M-24 :
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.
Keywords:
color match, integrally colored concrete, light resistance, pigment,, ICS Number Code 87.060.10 (Pigments and extenders),91.100.30 (Concrete and concrete products)
