Some trends in the use of concrete : Indian scenario

摘要

Concrete has undergone rapid and phenomenal development in the past few years in India. Revision of IS 456:2000 with emphasis on durability, appreciation of the quality assurance in general, setting up of a large number of RMC plants in metros, thrust on infrastructure development, etc have contributed to this growth and transformation. On the other hand, globalisation of the Indian economy paved the way for easy availability of micro-silica and latest superplasticisers in the country. M60 and higher grades of concrete are now becoming popular in the country with its proven utility in the construction of important structures. A brief account of the trends in the use of concrete and its production in the country is presented in the paper. Also presented is a glimpse of the current research and development scenario in the areas of self-compacting concrete, PQC and triple blend concretes in the country.
