About This Item

Legal Notices*

ASTM C88/C88M is the standard test method for soundness of aggregates by use of sodium sulfate or magnesium sulfate. It is used to evaluate how aggregate materials respond to repeated sulfate exposure, helping indicate their resistance to disintegration under test conditions. This makes it a useful reference for material qualification, acceptance decisions, and quality control when aggregate durability matters in construction and engineering applications.

What is ASTM C88/C88M?

This ASTM standard describes a test method for assessing the soundness of aggregates using sodium sulfate or magnesium sulfate. In practical terms, it provides a controlled way to measure how aggregate particles behave when subjected to cycles intended to simulate disruptive conditions. ASTM C88/C88M is commonly used as a technical basis for comparing aggregate quality and for supporting consistent testing practices across laboratories and projects.

Where is ASTM C88/C88M used?

The standard is generally used wherever aggregates are evaluated before being approved for use in construction materials. It is especially relevant in testing workflows for aggregate supply, specification compliance, and laboratory quality control. Because it focuses on soundness, the method is commonly associated with materials intended for concrete, asphalt, and other aggregate-based systems where durability and resistance to deterioration are important.

Why is ASTM C88/C88M important?

ASTM C88/C88M helps buyers, specifiers, and testing personnel make more consistent decisions about aggregate suitability. By providing a recognized method for soundness evaluation, it supports compliance with project requirements and reduces uncertainty during material selection. It also helps identify aggregates that may be more likely to break down under service or exposure conditions, improving reliability in procurement and performance-based quality control.
