alkali-silica reaction (physicochemical processes, <processes and techniques by specific type>, Processes and Techniques (hierarchy name)) |
|
Note: Materials-related distress arising from a simple acid-base reaction between alkali hydroxyl ions in portland cement and siliceous minerals. Found in many aggregates, it results in premature deterioration of concrete structures including bridges, dams, and pavements.

Additional Notes: |
|
| Dutch ..... Een verstoring die wordt veroorzaakt door een simpele zuur-basereactie tussen alkalihydroxylionen in portlandcement en in kiezelhoudende mineralen. Deze verstoring vindt plaats in veel aggregaten en resulteert in het voortijdige verval van betonnen constructies, zoals bruggen, dammen en bestrating. |
