²¹³ä¸ÃÊéµÄÓйØÐÅÏ¢£º Accession No 00754855 Authors Mehta, P K Publisher American Concrete Institute Editors Malhotra, V M Publication Date 19980000 Languages English Abstract 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.
