Abstract: In a field of construction, eco-friendly, cost and time are the three key factors which every civil engineer have to satisfies, For that purpose we use human hair which is going as a waste in our experimental study and determining the positive effect in the properties of concrete as fibre reinforced concrete. Annually 40 tones of hair is available throughout the world causing problems in degradation, by using hair as a fragmentary replacement of cement in concrete can reduce environmental problems. Though hair is a typical bio-degradable matter available in abundance at cheaper cost so that we can also reduce some cement content and cost factor. On the other hand a new technology named self-compacting concrete which is developed by the skilled work man ship is used. Using SCC can shorten the time and decrease the cost of building process. SCC has good elastic property in fresh state and have high resistance to segregation, it can spread under gravity due to its self weight without any vibration or compaction. The incorporation of randomly distributed hair fibre in SCC enhances its tensile property (i.e. human hair is strong in tension), and effective in delaying micro cracks and also hope combination of these two made a new technology views saving environment and making a construction with ease come reducing cost and saving the time of project. Experiments were conducted on concrete cubes of standard sizes (0.15m3 ) with addition of different proportions of human hair fibres (i.e. 0%, 0.25%, 0.5%, 0.75%, and 1%) by weight of cement. In this work, fly ash is used as mineral admixture and PCE based super plasticizer as chemical admixture for achieving fluidity nature. For each percentage of hair fibre added in concrete, the 7 days, 14 days and 28 days compressive strength of cubes are obtained by crushing in compression testing machine.
