Abstract : With restrictions on indiscriminate dredging of river sand and breaking of mountains there has been a growing need in civil construction industry for identification of alternate eco-friendly aggregates. Some of the feasible and economical solutions that have emerged in recent years are to reuse the industrial process wastes such as slags and recycled aggregates through reprocessing. In India use of alternative aggregates has never been popularized due to nonavailability of codes, specifications, standards and guidelines. With ecological concerns and environmental restrictions, availability of natural aggregates is greatly reduced and most of the developed countries have amended their aggregate standards to allow alternative or artificial aggregates such as slags and recycled concrete, in roads and construction. Much of research has been carried out on various alternative aggregates, its testing, specifications and limit of applications. It is the time in India to change/amend the existing standards to include artificial and recycled materials as aggregates along with natural materials. This paper highlights the scope of alternative aggregates, their specifications and required amendments in the standards.
