ASTM C1797 is the ASTM standard specification for ground calcium carbonate and aggregate mineral fillers intended for use in hydraulic cement concrete. It provides a technical basis for describing and evaluating these filler materials so they can be selected with greater confidence in concrete-related applications. For buyers, specifiers, and quality teams, the standard helps support more consistent material procurement and product comparison when mineral fillers are part of the concrete mix design.

What is ASTM C1797?

ASTM C1797 sets out a specification framework for ground calcium carbonate and aggregate mineral fillers used in hydraulic cement concrete. As a product-focused ASTM standard, it is intended to guide how these filler materials are identified and considered for concrete use. The standard is relevant when a mineral filler must meet defined expectations for quality and consistency. In practice, ASTM C1797 supports clearer communication between suppliers, laboratories, and end users.

Where is ASTM C1797 used?

ASTM C1797 is commonly used in concrete material supply, specification review, and quality control workflows where ground calcium carbonate or aggregate mineral fillers are incorporated into hydraulic cement concrete. It is relevant to producers, testing laboratories, and project teams that need a shared technical reference for filler materials. The standard is typically used during material selection, procurement review, and acceptance documentation for concrete ingredients that include mineral fillers.

Why is ASTM C1797 important?

ASTM C1797 matters because it gives stakeholders a consistent specification reference for mineral fillers used in hydraulic cement concrete. That consistency can help reduce ambiguity in purchasing, testing, and product evaluation, especially when comparing materials from different sources. Using the standard may also support better quality control and compliance efforts by giving specifiers and suppliers a common technical language. For concrete-related applications, that clarity can help lower the risk of mismatched expectations.
