A state-of-the-art review
When compressive strength drops, coconut shell is replaced. As a result coconut shell concrete is employed as low weight concrete [22]. Kanojia, Apeksha (2017) results showed after replacing 40% coarse aggregate with coconut shell, compressive strength of concrete decreased by 62% over 7 days but only by 21.5% over 28 days.
