Role of Pozzolanic and Cementious Material in Sustainable Development of the Concrete Industry

Among the major problems facing the concrete industry at the end of the twentieth centry are the enormous infrastructural needs of a rapidly urbanizing world, the premature deterioration of many concrete structures, the need to improve concrete durability in a cost-effective way, and increasing public interest in finding ecological solutions for safe disposal of millions of tons of industrial by-products that might be suitable for incorporation into cementitious materials and concrete. In this paper the author shows that all these problems are interrelated and can be resolved by adopting a holistic approach.
