About This Item
ASTM C897 is the ASTM standard for aggregate used in job-mixed Portland cement-based plasters. It provides a clear technical reference for the materials placed into plaster mixtures, helping support consistency in sourcing, quality control, and product evaluation. By defining the aggregate-related requirements for this application, the standard helps buyers and producers align on material expectations and reduce uncertainty during specification and procurement.
Purpose of ASTM C897
The purpose of ASTM C897 is to establish a specification for aggregate intended for job-mixed Portland cement-based plasters. In practical terms, it serves as a common basis for evaluating whether an aggregate is suitable for this use and for communicating requirements between suppliers, contractors, and specifiers. The standard is especially relevant where material consistency matters, since aggregate selection can affect mixture control and the overall performance of the plaster system.
Common use cases of ASTM C897
This specification is commonly used when selecting aggregate for field- or site-mixed Portland cement-based plaster applications. It is useful in procurement documents, material submittals, and quality checks where the aggregate source must be matched to the intended plaster work. ASTM C897 may also support acceptance decisions during product review, helping project teams confirm that the aggregate aligns with the expected plaster formulation and job conditions.
Why ASTM C897 matters
ASTM C897 matters because consistent aggregate selection can influence both compliance and day-to-day construction results. Using a recognized specification helps reduce ambiguity in purchasing, testing, and inspection, which can improve coordination among suppliers and users. For specifications involving job-mixed Portland cement-based plasters, this standard provides a practical reference point for quality control and material consistency, supporting more reliable outcomes and lowering the risk of avoidable product variation.
