What is ASTM C979 primarily concerned with?

• A. Curing compounds for concrete
• B. Pigments for integrally colored concrete
• C. Corrosion-inhibiting admixtures
• D. Mixing techniques

Answer: (B)

ASTM C979 focuses specifically on the use of pigments in integrally colored concrete. This standard provides guidelines for the quality and performance of pigments used to color concrete mixtures, ensuring that they achieve consistent color and compatibility with various concrete formulations. The inclusion of pigments is essential in achieving desired aesthetic characteristics while maintaining the structural integrity of the concrete. This standard helps manufacturers ensure that the products meet predetermined specifications for color intensity, stability, and overall performance in concrete applications, thus enhancing the visual appeal and marketability of concrete products. Understanding the significance of ASTM C979 is crucial for professionals involved in concrete production, as it ensures that any color added to the mixture does not compromise the durability or workability of the concrete while achieving the intended design appearance.
