Corrosion and Corrosion Protection of Prestressed Ground Anchorages


Book Description

This state of the art report summarizes the mechanisms and types of corrosion to which a ground anchorage based on a prestressing tendon can be subjected. The chemical, electrochemical and bacterial reactions between agressive soils and steel and concrete are dealt with in detail. There is a carefully recorded and analysed list of a number of known cases of tendon corrosion. A corrosion protection philosophy is proposed, with five classes of protection, with examples of such protection in current practice.

Factory Applied Corrosion Protection of Prestressing Steel


Book Description

Without doubt, active corrosion protection of prestressing steels by cement grout can be one of the most economic and durable solutions, if properly executed. Numerous other corrosion protection systems which fulfill requirements such as controllability and exchangeability are available. This state-of-the-art report, prepared by a task group and approved by fib Commission 9 Reinforcing and prestressing materials and systems, concentrates exclusively on factory applied corrosion protection that can be produced in controlled processes which should assure a better quality than corrosion protection applied on site. The report is addressed to designers and installers (executing persons) attempting to inform them about the various possibilities for industrially applied corrosion protection and to provide the necessary knowledge for their application.




Ground Anchorages and Anchored Structures


Book Description

This volume presents the proceedings of the first major international conference for over twenty years on the state-of-the-art of ground anchorage technology. Practical issues relating to construction and installation of anchorages are considered in a series of examples of engineering projects from around the world.
