The attempts to produce crushed or manufactured sand in India could be traced to early 50's primarily in major dam works. The focus was on using different size reduction techniques with available resources like rod mills, roller -crushers, and cone crushers.
The absence of research in the reputed Civil Engineering Institutions about manufactured sand aided a lot of unscrupulous quarry operators to perpetuate the myth that quarry dust can be used in production of concrete either by complete or partial replacement of river sand.
The progress in the building material research and identification of role of particle shape and gradation of fine aggregates triggered the use of manufactured sand in the production of concrete. The complexity of construction and use of high strength concrete in large number of buildings is the prime mover along with the scarcity of river sand in many cities.
