Corrosion Effects of Cement Stabilized Backfill on Galvanized Steel EarthReinforcements

摘要

Cement stabilization of backfill has been used for some time in mechanicallystabilized earth type retaining walls. However, there has been no data on the corrosion life of galvanized steel reinforcement in this environment, which is intermediate in pH between normal soil and pure cement. Field observations had indicated a potential corrosion problem at a particular site in District 12. The use of crushed concrete as backfill did not accelerate corrosion. This material, therefore, appears to be acceptable for this application.
