Integrated Design and Environmental Issues in Concrete Technology

The two themes of integration of structural and durability design, and integration of concrete technologies in relation to global environmental issues are drawn together in this book. It presents the views of distinguished international researchers and engineers on these key topics as the 21st century approaches. Derived from a workshop on rational design of concrete structures held in Hakodate, Japan, in August 1995, the book provides a focus for debate about the ways in which concrete technologies around the world must respond to the necessity of ensuring that concrete construction achieves higher levels of durability, and about the growing imperative to meet higher environmental standards in concrete production and use.
