Abstract:
Lucinda Jetty is a 5.76 km structure located in north Queensland. The jetty is part of the Lucinda Bulk Sugar Terminal operated by Queensland Sugar Limited. The deck consists of prestressed concrete girders supported by steel headstocks and piles. Soon after construction in 1979, concrete cracking in the girders was observed and this was subsequently attributed to alkalisilica reaction (ASR). The jetty has been the subject of detailed investigations and comprehensive monitoring since the mid 1980s. A regular monitoring program is currently in place and provides a unique record of condition versus time. Monitoring includes visual inspection and measurement of half cell potentials, transverse and longitudinal expansion, chloride ion ingress and response to load testing at selected locations
