摘要：The high cost of conventional construction material affects economy of structure. With increasing
concern over the excessive exploitation of natural aggregates, synthetic lightweight aggregate produced from
environmental waste is a viable new source of structural aggregate material. It is also help in reducing the cost of
concrete manufacturing. In the present work coconut shell as partial replacement for coarse aggregate and
manufactured sand as partial replacement for fine aggregate in concrete is used. Density of coconut shell is in the range
of 550-650 kg/m3 and these are within the specified limits for light weight aggregate. Water used for mixing of
concrete is potable water.Cube will be casted and the compressive strength and workability will be evaluated at 7, 14
and 28 days. Its utilization is cost effective and eco-friendly.
