2017-5-8  Research carried out by compared concrete made with coconut shell and palm kernel shell as replacement of coarse aggregate and concluded that coconut shell performed better than palm kernel shell in concrete in terms of strength. Studies by also indicated some of the advantages of using coconut shell as coarse aggregate replacement in concrete include high strength, reduction of dead load, modulus properties and lignin content. The high lignin content makes coconut shell aggregate concrete to be weather resistant and hence suitable for application as construction materials. More so, research by reported that the shells absorbs less moisture due to its low cellulose content, others are superior mechanical properties, reduction of shrinkage in concrete, reduction in permeability of concrete, increase resistance against chemical effect which results in the formation of denser concrete. Reference also identified that there is about 48% reduction in cost if coconut shells are properly used to replace coarse aggregate in concrete. This study is therefore, aimed at assessing the strength properties of concrete containing coconut shell as coarse aggregate replacement in concrete.
