PARTIAL REPLACEMENT OF FINE AGGREGATE WITH BRICK DUST: A REVIEW

Abstract

The widely used material in infrastructure development and construction throughout the world is concrete
and mortar. A significant role in the mix design is played by fine aggregate and coarse aggregate which are the prime
material used for the preparation of mortar and concrete. River sand is becoming a scarce commodity nowadays.
Hence the manufactured sand is playing a major role in the construction industry nowadays. The natural resources
due to excessive use are also exhausting very rapidly. Shortage of fine and coarse aggregate may affect construction
industry directly, therefore there is a need to find an alternative material which can replace fine aggregate or coarse
aggregate fully or partially so that the damage due to excessive erosion to the environment is prevented.
Thus the replacement of fine aggregate and coarse aggregate became a necessity in the recent times and this partial
or complete replacement will contribute a lot to nature and environmental problems created due to excessive use and
dumping of brick debris or construction waste. This research review will discuss the partial replacement of fine
aggregate with brick dust and how to reduce the dependency on the natural resources such as sand used as fine
aggregate and provide a new way to dispose of waste brick debris. Different replacement levels 10%, 15%, and 20%,
will be checked. Different tests showed that the compressive strength is enhanced by using optimum percentage
replacement of natural fine aggregate with brick debris compared to conventional mortar and concrete
