Conservation of natural resources and prevention of environment is the essence of any development of the problem
arising from continuous technological and industrial development is the disposal of waste materials. If some of the waste materials are
found suitable in concrete making, the cost of construction can be cut down, but also safe disposal of waste materials can be achieved.
So an attempt has been made to access the suitability of different replacement materials in the concrete making. The project
implemented to coconut endocarp. Using Engineering properties of OPC cement and also the design mix (1:1.25:2.93) of concrete is
M20 grade of concrete. The 7th and 28th day compressive strength, Split tensile strength and flexural strength of conventional concrete
and coconut shell ash (CSA) concrete with replacement of 5% to 25%. Finally the results are tabulated and comparisons are plotted
using graphs.
