Presents techniques of applying and repairing concrete in freshwater and marine environments for the practicing engineer. Covers materials, inspection, defect evaluation, repair methods, and factors influencing long-term durability of concrete underwater. Includes numerous diagrams and photos. Enables engineers to identify and overcome the many problems associated with concreting in both fresh and sea water. Focuses on the major factors influencing long term durability of concrete in the underwater environment. Discusses inspection, evaluation of defects and methods of repair for existing underwater structures. --
This essentially practical book will enable engineers to identify and overcome the many problems associated with concreting underwater. Written by experts in the field, it contains much information plus extracts from recent research programmes and presents current ideas and techniques.
"In addition, four case studies are presented to illustrate the application of the above knowledge. The first case study describes the special aspects of underwater repairs to a concrete storm surge barrier damaged during construction. The second case study summarizes the procedures used for repairing a cracked concrete gravity dam by polyurethane resin injection methods. The third case study presents the various procedures used for repairing concrete railway bridge piers in a marine environment which were damaged by severe alkali-aggregate reaction. The final case study describes underwater repair procedures and concrete investigation techniques used in repairing the piers of a highway bridge." --
The success of a repair or rehabilitation project depends on the specific plans designed for it. Concrete Structures: Protection, Repair and Rehabilitation provides guidance on evaluating the condition of the concrete in a structure, relating the condition of the concrete to the underlying cause or causes of that condition, selecting an appropriate repair material and method for any deficiency found, and using the selected materials and methods to repair or rehabilitate the structure. Guidance is also provided for engineers focused on maintaining concrete and preparing concrete investigation reports for repair and rehabilitation projects. Considerations for certain specialized types of rehabilitation projects are also given. In addition, the author translates cryptic codes, theories, specifications and details into easy to understand language. Tip boxes are used to highlight key elements of the text as well as code considerations based on the International Code Council or International Building Codes. The book contains various worked out examples and equations. Case Studies will be included along with diagrams and schematics to provide visuals to the book. Deals primarily with evaluation and repair of concrete structures Provides the reader with a Step by Step method for evaluation and repair of Structures Covers all types of Concrete structures ranging from bridges to sidewalks Handy tables outlining the properties of certain types of concrete and their uses
