PARTIAL REPLACEMENT OF AGGREGATES WITH COCONUT SHELL IN CONCRETE: A REVIEW

Abstract

Diverse waste materials, for example, fly ash, silica fumes, copper slag, devastated concrete has been
effectively utilized to create different materials for building development, for example, concrete , flush doors,
plywood and so forth. Aggregate is a noteworthy element for influencing concrete, to involve right around 70-80%
of cement. Traditionally pulverized rocks are utilized as coarse aggregate and river sand as fine aggregate. Both are
naturally accessible material. Because of quick development of construction exercises, traditional aggregates
sources are exhausting quick prompting noteworthy increment in expense of construction. For sustained
development, these materials ought to be utilized carefully and elective materials should be sought to supplant
conventional aggregates. Expansive number of studies has been done to scan elective materials for generation of
concrete. In the meantime because of quick industrialization, generation of waste material is expanding
continuously. Its disposal has turned out to be a genuine issue. Answer for this issue is to get rid of it by landfilling
on site or utilize this waste for some positive activity. Space for landfill site is winding up expense issues. In
perspective of this the alternative is it is possible that we ought to limit the waste at production level, or use it. India
is the third biggest coconut creating nation on the planet. Ample measure of waste is created by coconut. The waste
coconut shell might be utilized to supplant traditional coarse aggregate. The point of this paper is to deliver issue
related to scarcity of conventional material, issues of disposal of waste material and assess the works done on
utilization of waste coconut shell for production of concrete.
