Feb 05, 2019· The water absorbed by the coconut shell during the course of soaking is stored and the pore structure in the coconut shell behaves like a reservoir. Intermittent curing condition produces the highest coconut shell aggregate concrete strength followed by full water curing . Coconut shell concretehave a good quality in itslater stage.
Abstract: Silica fume has been used for many years as a fine-grained supplementary cementitious material in ultra-high performance concrete (UHPC) to aid in improving strength and durability. Since silica fume is a waste product, much variability is present among different silica fume sources.

In this study the fine aggregate was replaced by PET, rubber crumb and coconut shell at 10, 20 and 30 % by weight of binder and tested for 7, 28 and 60 days of curing. The overall compressive strength of concrete decreased when fine aggregate was replaced with PET, rubber crumb, coconut shells and rubber crumb with either PET or coconut shells.
A combination of Egg shell with silica fumes are used in different combinations to find the feasibility of using the Egg shells as an alternate to cement Egg shell powder replaces 10%, 20% and 30% in addition with the silica fume by 5%, 10%, 15% of weight of cement. Concrete is cast and Compressive test, Tensile and Flexural tests
