ABSTRACT: There has been a consistent research in the field of construction industry in a view to produce a concrete which could able to resist all varieties of loads. A concrete should be good at compressive strength, flexural strength and split tensile strength and should also be durable enough for all kinds of extreme environment conditions. Since years, the research is still under progress and there has been an evolution of various types of concrete which are having their own applications. In my present work, waste egg shell powder is being used as one of raw material in concrete. In addition to egg shell powder, a small amount of coconut fiber is also added to examine the change in the mechanical properties of concrete. Egg shell powder is used as a substitution in place of cement in various percentages such as 3%, 6%, 9% and 12% and initially the experiments were conducted to determine the properties, without including coconut fiber. In the second set, both egg shell powder and coconut fiber are introduced and the tests were conducted. Coconut fiber is added as 0.5%, 1%, 1.5% by volume of concrete in each percentage replacement of egg shell powder and tests were conducted to know the properties. For every replacement, water absorption tests were also conducted and studied.

KEYWORDS: Egg shell powder, coconut coir, water absorption, compressive strength, flexural strength.
