Abstract: In construction industry the rising cost of construction materials is the major factor. The high cost of conventional building materials is the greater factor effecting housing delivery in the world. The project aim is to analyze compressive strength characteristics of concrete produced using crushed, granular coconut shell and quarry dust as substitute for conventional coarse and fine aggregate respectively with partial replacement. Coconut shell is the natural material which is commonly available in all over the world. It is an abundant, versatile, renewable and cheap remain in the environment as waste material. Quarry dust which is a waste product from aggregate crushers could replace sand. It has very recently gained good attention to be used as an effective filler material instead of fine aggregate. So the utilization of these materials for construction will be an important step to improve sustainability and eco-friendly construction. They must be accessible to the standard individuals and be low in financial value. It is economically profitable material in the construction field. The main purpose is to encourage the use of these waste products as construction material to reduce the cost of housing. In this studies, two different concrete mixtures i.e., M 20 and M 40 with different combination of natural materials content namely 0%, 5%, 10% and 15% of coconut shell and as well as 0%, 15%, 30% and 45% of quarry dust. The compressive strength of concrete reduced as the percentage replacement of coconut shell increased and to compensate this compressive strength quarry dust is replaced with fine aggregate. Properties like compressive strength, water absorption, specific gravity were investigated in the laboratory. Workability decreased with increase in coconut shell replacement and increased with increased in quarry dust replacement. All precautions are taken to maintain serviceability, strength and durability. Thus it will be helpful for civil engineers and society to adopt this concept to fulfill the basic need of human that is housing.
Key words: Coconut shell, Quarry dust, Coarse aggregate, Fine aggregate, Cement, Compressive strength.
