Extending the Service Life4

Cronulla Marina: Cronulla, NSW, Australia

The Cronulla Maria was built in 1994. The concrete was a specially designed, 50year service life, concrete mix which incorporated  Xypex Admix , for protection of the reinforcing steel from chloride ingress. In May 2013, independent consultants carried out extensive testing for chloride levels and corrosion potential and it was determined that "the predicted critical chloride concentration of 0.4% by weight of cement at 40mm is reached at an age of 129 years with the current exposure conditions."
