This publication of 111 papers from around the world has been designed to examine the effect of various concreting materials and construction techniques on the ability of hydraulic cement concretes to remain durable under various aggressive exposure conditions found in todays environment. Examines the present state of knowledge, identifies and discusses problems and known solutions, and determines what improvements in practice are needed and how they may be achieved. Published in two volumes, and divided by subject matter (sulfate attack, alkali aggregate reaction, abrasion, corrosion and others) topics covered include durability of high strength concrete, why we have concrete durability problems, concrete durability in bridges, fly ash and concrete durability - and much more.
