Abstract - The present study aims at exploring the effect

strength. So there is good chance of formation of microcracks may later propagate to larger area thus causing a brittle failure. Incorporating hair fibre in concrete can prove a wise move as hairs are good crack arresters hence it will increase the tensile strength of con- Crete. Addition of hair fibres can help in reducing permeability and also help in controlling plastic shrinkage of concrete. Hence hair fibres in concrete will make concrete more homogeneous and isotropic in existence. GGBS which is ground granulated blast furnace slag is a waste material derived from manufacturing industries. India which is hugely populated where infrastructure development is heading at a faster pace in which cement is enormously consumed which is directly causing pollution in the environment. Hence partially substituting cement with GGBS will help in keeping a check on environmental degradation. Replacing GGBS with ordinary Portland cement will help in elevating the strength properties of concrete.

of Human hair and GGBS replacements on different properties of concrete and finding the efficient and alternate way for disposing the solid wastes to reduce the pollution generated from these wastes. The research focuses on both structural as well environmental implications of both human hair and GGBS. The different specimens consisting of both GGBS and human hair were casted and tested on CTM. The results of control specimens were also determined and comparisons of different samples have been illustrated in both graphical as well as in tabular form. From research findings it has been found that there is improvement in strength parameters of concrete with the incorporation of human hair along with GGBS. Strictly from the research it is observed that the maximum strength derived is at 1% human hair and 20% GGBS replacements. With the addition of both waste materials there is reduction in dead load of the structure thus this exploration would turn out to be quite useful for those structures where emphasis is on using lightweight materials.

2.1. Test on Cement:-

1. INTRODUCTION

The test on cement was carried for finding out its various physical properties using the following codes [IS 4031(part 3),IS 4031(part 4), IS 4031(part 5), IS 2720(part 3)]. The properties are given in table

In this present era there is huge necessity of fast and economic construction thus in order to achieve that various construction companies are incorporating admixtures into their into their construction process. One among them is the specific use of ground granulated blast furnace slag (GGBS) and human hair fiber which are both solid waste materials generated from industries and from human beings respectively. Concrete is used everywhere around the world to make the dream come true as the visualizing design adapted. Concrete is solid block made out of cement, water and aggregates. In real terms aggregates doesn’t play the crucial role of binding but it’s the filler material which are added that reduces voids in the dense matrix. Binding but it’s the filler material which is added that reduces voids in the dense matrix. Concrete is used to construct various elements like beams, slabs, domes, foundations and columns so concrete quality and economy is a must in this specified elements. Utilizing waste materials is really a benefit as it will help in huge decline in level of environmental deterioration but also parallel extraction of natural vital resources like fine aggregates, cement is also reduced. Concrete is very weak in tension and also has less tensile
