Description
Products from the corrosion of steel reinforcement, rock bolts and volume-expanding ettringite/monosulphate (see 5.3/2.07) or Friedel salts (chlorides) may form within the backfill. Due to volume increase the concrete may be disrupted. This would not affect mass transport significantly.
