Protection against earthquakes and astm c295. The petrographic examination should establish whether the aggregate contains chemically unstable minerals such as soluble sulfates, unstable sulfides that may form sulfuric acid or create distress in concrete exposed to high temperatures during service, or volumetrically unstable materials such as smectites formerly known astm c295 the montmorillonite-saponite group of aastm or swelling clays.
