Advanced civil infrastructure materials
Concrete and steel are by far the most widely used man-made construction
materials in the world. Despite numerous successful constructions of worldwide
infrastructures, many of these infrastructures are now rapidly deteriorating.
It has been estimated that infrastructure rehabilitation costs, in the US alone,
will reach into trillions of dollars over the next twenty years. One of the
primary causes for the decay of our infrastructures is the deterioration of the
materials used in the construction and repair of these structures. Intrinsically,
concrete is brittle hence vulnerable to cracking, whereas structural steel is
heavy and prone to corrosion. These alarming infrastructural problems indicate
an urgent need for more durable construction materials ultimately to replace
conventional concrete and steel, and most likely to supplement these popular
materials in the near future.
In recent decades, material development in response to the call for more
durable infrastructures has led to many exciting advancements, especially
the paradigm design example of Fiber Reinforced Plastics Composites which
enjoys tremendous success in the aerospace and automotive industries. It has
inspired many composite designs involving concrete and wood. These fiber
reinforced composites, with unique properties, are now being explored in
many infrastructural applications. Even concrete and steel are being steadily
improved to have better properties and durability. Such advancement also
makes it possible to use advanced concrete or steel in an unprecedented way.
The purpose of this book is to provide an up-to-date review of several
emerging construction materials that may have a significant impact on repairs
of existing infrastructures and/or new constructions. Two areas take high
priority in this book. First, we emphasize the materials design concept which
leads to the creation of advanced composites by synergistically combining
two or more constituents. Such design methodology is made possible by
several key advancements in materials science and mechanics. Second, we
conclude each chapter with selective examples of real-world applications
using such advanced materials. This includes relevant structural design
guidelines and mechanics to assist readers in comprehending the uses of
these advanced materials.
