The scientists emphasize that improving the quality of concrete used in creating marine structures can be accomplished by making it less permeable and increasing the clear cover.
Officials from some states told the U.S. Government Accountability Office that they use sealant on bridge decks to prevent corrosion.
In order for steel bridges to economically meet a 100-year design life, protective coatings with very long durability are needed to reduce maintenance costs. Thermal spray zinc (TSZ) duplex coatings have proven to be very durable.
A recent report from a civil engineering form suggests that San Diego’s Ocean Beach Municipal Pier has suffered significant damage over the last 55 years and “has reached the end of its service life,” as presently constructed.
Staff and leaders from the Association for Materials Protection and Performance (AMPP) and the International Union for Painters and Allied Trades (IUPAT) recently convened to renew their longstanding partnership, with a goal of increasing quality and public safety.
There are many offerings for both above- and below-ground pipeline isolation. But only certain designs may be appropriate, considering the varied applications that pipelines have, changing conditions, and the need to design for a sustainable future.
Viscoelastic coatings have been successfully used over the past two decades to solve corrosion issues in various circumstances. Highly aggressive soils, such as the Subkha soil in the Gulf Coast area, require excellent performance by a coating.
