The high cost of construction materials like cement and reinforcement bars, has led to increased cost of construction. This, coupled with the pollution associated with cement production, has necessitated a search for an alternative binder which can be used sorely or in partial replacement of cement in concrete production. More so, disposal of agricultural waste materials such as rice husk, groundnut husk, corn cob and coconut shell have constituted an environmental challenge, hence the need to convert them into useful materials to minimize their negative effect on the environment. Research indicates that most materials that are rich in amorphous silica can be used in partial replacement of cement. It has also been established that amorphous silica found in some pozzolanic materials reacts with lime more readily than those of crystalline form. Use of such pozzolana can lead to increased compressive and flexural strengths.The American Society of Testing Materials (ASTM) defines Pozzolans as siliceous or aluminous materials which possess little or no cementitious properties but will, in the presence of moisture, react with lime [Ca (OH)2] at ordinary temperature to form a compound with pozzolanic properties. Recycling of the disposed material is one method of treating the agricultural waste. The used of coconut fiber and coconut shell could be a valuable substitute in the formation of composite material that can be used as a housing construction, such as concrete hollow block [1].
