Concrete is an inherently complex material to produce and an even more complex material to repair. With growing pressure to maintain the built environment, and not simply to demolish and rebuild, the need to repair concrete buildings and other structures is increasing and is expected to become of greater importance in the future.
This straightforward book serves as a practical guide to engineers on the processes to be followed in commissioning a concrete repair. It stresses the need to fully understand the cause, extent and location of the problem, by appropriate insitu and laboratory testing. And it outlines the steps to a successful repair. It includes sections on the different repair techniques, giving good practical advice as to where and when to use them, and the warns of the pitfalls of their incorrect use. It also includes an up-to-date guide on the current standards for repair, and provides a good bibliography on other sources of information and books on the various techniques.

An industrial book that analyzes various theoretical problems, optimizes numerical applications and addresses industrial problems such as belt-conveyor bridge, pipeline, wind turbine power, large-span suspended roof and offshore jacket member. Multi-storey frames and pressure vessel-supporting frames are discussed in detail. The book’s emphasis is on economy and cost calculation, making it possible to compare costs and make significant savings in the design stages, by, for example, comparing the costs of stiffened and un-stiffened structural versions of plates and shells. In this respect, this book will be an invaluable aid for designers, students, researchers and manufacturers to find better, optimal, competitive structural solutions.

Sulfur construction materials can offer improvements over more traditional materials, especially in specific applications. These materials include sulfur concrete and sulfur-extended asphalt pavements as well as pre-cast concrete components, extrusions, and cast-in-place forms.
This one-of-a-kind book discusses the basic properties and behavior of sulfur cement and concrete materials and, based on these properties, new sulfur market applications are evaluated and the technological aspects of material production are presented.
Key Features:
--Reviews acceptable methods of disposing of unneeded sulfur without compromising environmental protection
--Reveals the advantages of using modified sulfur concrete materials for sub-ground and sub-marine structures, and immobilization of hazardous wastes
--Describes the unique features of sulfur construction materials such as corrosion resistance, low moisture penetration, high thermal and mechanical performance, and long-term stability in various environments
--Discusses sulfur concrete process design for use in waste management practices (barrier systems for waste containment, stabilization/solidification of waste, etc.)

The civil engineering sector accounts for a significant percentage of global material and energy consumption and is a major contributor of waste material. The ability to recycle and reuse concrete and demolition waste is critical to reducing environmental impacts meeting national, regional and global environmental targets. The editors and expert contributors summarize recent research in achieving these goals. Part one considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants, and the economics of managing construction and demolition waste. The middle section reviews key steps in handling construction and demolition waste. It begins with a comparison between conventional demolition and construction techniques before going on to discuss the preparation, refinement and quality control of concrete aggregates produced from waste. It concludes by assessing the mechanical properties, strength and durability of concrete made using recycled aggregates. Finally, the conclusion discusses environmental and safety issues such as the removal of gypsum, asbestos and alkali-silica reaction (ASR) concrete, as well as life cycle analysis of concrete with recycled aggregates.
