The aim of this study is to Using waste product like bottle caps and coir fibre to make ecofriendly concrete. Large quantities of waste can be generated from empty cans and bottle caps of juices and soft drinks. This study is aimed at addressing such issues by investigating the possibility of using waste bottle caps to partially substitute for coarse aggregate in concrete production. Hence an attempt has been made in present investigations to study the influence of addition of waste materials bottle caps dosage of 0%, 1%, 2%,3% , 4% & 5% of total weight of coarse aggregate .M20 grade of concrete was produced by replacing coarse aggregate by plastic bottle caps .Coir fibre is a natural fibre is a natural consist of cellulose , lignin ,pentosans and ash in varying percentage when dried . Also coir fibre is locally and economically available. Hence an attempt has been made in present investigations to study the influence of addition of coir fibre dosage of 2% of total weight of cement. Addition of coir fibre increases the crack resistance of concrete, produces the structural light weight material. Hence coir fibre can be used in construction and can reduce environmental waste by proper utilization. Also the use of coir fibre is cost effective and eco friendly.
