Learn how to perform the Standard Test Method for Soundness of Aggregates by Use of Sodium Sulfate or Magnesium Sulfate (ASTM C88). This test determines the resistance of aggregates to weathering and disintegration when exposed to freeze-thaw cycles or other environmental conditions.
In this video, we cover:
0:00 Introduction to Aggregate Soundness
1:12 Required Apparatus and Materials
3:45 Sample Preparation and Sieving
6:20 Immersion in Sulfate Solution
8:55 Drying and Cycling Process
12:30 Final Sieve Analysis
15:10 Calculating the Weighted Average Loss
18:05 Interpreting the Results & Spec Limits
This test is critical for ensuring the durability of concrete and asphalt pavements, bases, and other construction applications.
