Abstract -The cost of conventional building materials is
rising day by day which is of great concern, which forces us to use alternative materials for civil engineering construction. Different waste materials such as fly ash, silica flumes, copper slag, brick bat, demolished concrete has been successfully employed to produce various materials for building construction such as concrete, flush door, plywood, jute boards etc. Aggregate in abundance is required for making concrete, it occupies almost 70-80% part of concrete. Conventionally crushed rocks are used as coarse aggregate and river sand as fine aggregate. Both are naturally available material. Due to rapid growth of construction activities, conventional aggregate sources are depleting very fast leading to significant increase in cost of construction. For sustainable development, these materials should be used wisely and alternative materials need to be searched to replace conventional aggregate. Large number of studies has been done to search alternative materials for production of concrete. India is the third largest coconut producing country in the world. Huge amount of waste is generated by coconut. The waste coconut shell can be used as conventional coarse aggregate. It may help to produce concrete economically and at the same time also will help to reduce its disposal problem.
Keywords: Concrete, Coconut Shells, Compressive Strength, Coconut Shell Concrete.
1. INTRODUCTION Increase in waste is directly proportional to increase in population. As population of India is constantly increasing waste is increasing. To control this waste we can reuse, reduce or dispose it by some chemical process. As advancement in infrastructure created demand for construction material, concrete is premier civil engineering construction material and among all aggregate form the major part. So we thought of using agricultural waste in construction industry i.e. as partial replacement of coarse aggregate. Different waste materials such as fly ash, silica flumes, copper slag, brick bat, demolished concrete has been successfully employed to produce various materials for building construction such as concrete, flush door, plywood, jute boards etc. © 2017, IRJET

Aggregate in abundance is required for making concrete, it occupies almost 70-80% part of concrete. Popularity for concrete in the construction that uses normal weight aggregates like gravel and granite significantly reduces the natural stone deposits and this cause’s environmental degradation leading to ecological imbalance, there is a need to explore and to find out suitable replacement material to substitute the natural stone. Many developed countries, are using natural materials like Pumice, Scoria and Volcanic debris and manmade materials like expanded blast-furnace slag, vermiculite and clinker as substitutes for natural stone aggregates. Lightweight aggregate concrete (LWAC) is vital and flexible material in modern construction. Low density and superior thermal insulation properties makes it popular. Many architects, engineers, and contractors appreciate the intrinsic economies and benefits offered by this material. Although lightweight concrete has strengths comparable to normal concrete; it is typically 25-35% lighter. Structural LWC gives design flexibility and reduces cost due to self-weight reduction, improved seismic structural response, and lower foundation costs. Transportation and placement costs are low in lightweight precast element. High porosity of light weight concrete gives low specific gravity. Commercially available lightweight aggregate has more demand for manufacture of LWC, but more environmental and economical benefits can be achieved if waste materials can be used as lightweight aggregates in concrete. In view of the increasing environmental harms, the use of aggregates from by-products and/or solid waste materials from various industries is highly enviable. In recent years, researchers have also paid more attention to some agriculture wastes for use as building material in construction. In India, use of non-conventional aggregates in concrete construction should take place commercially.
