About This Item

Legal Notices*

ASTM C404 is the standard specification for aggregates for masonry grout, giving buyers, specifiers, and quality teams a clear technical reference for material selection. It helps define the characteristics expected of aggregates used in masonry grout so that products can be evaluated consistently for project requirements. By using this ASTM standard, stakeholders can support more reliable procurement, better material control, and a more consistent grout supply for masonry applications.

What is ASTM C404?

ASTM C404 is a specification focused on the aggregates used in masonry grout. As a product-page reference, it identifies the technical framework for describing and evaluating those aggregates rather than the grout itself. The standard is useful when a project needs a common basis for ordering, reviewing, or verifying aggregate materials intended for grout applications. In practice, it supports clearer communication between manufacturers, suppliers, and specifiers.

Where is ASTM C404 used?

ASTM C404 is commonly used in masonry-related procurement and quality control workflows where grout aggregates must meet a defined specification. It is relevant when selecting aggregate materials for grout intended for masonry construction, including projects that require consistent material documentation and review. The standard may also be used by labs, suppliers, and specifiers who need a shared technical reference during submittals, acceptance checks, or material comparison.

Why is ASTM C404 important?

ASTM C404 matters because a clear aggregate specification helps reduce ambiguity in product selection and evaluation. It supports compliance efforts, helps align purchasing with project requirements, and provides a more consistent basis for quality control. For teams working with masonry grout, this can reduce the risk of material mismatch and improve confidence in technical documentation. ASTM C404 is especially useful when uniformity and specification-driven decision-making are important.
