Abstract This study is intended to explore the self-healing capacity of the concrete and suitability of medical vial waste as fine aggregate in concrete. Concrete is the product which is widely used in the construction industry. The problem faced in the concrete is the repair cost after construction due to the formation of cracks in them and can be overcome by usage of some kind of nonpathogenic bacteria in the concrete which will reduce the repair cost. Bacillus sphaericus is a satisfactory bacterium for application in self-healing concrete based on inclusion of bacteria. It also had been found that the disposal of waste vial glasses is polluting the environment. The usage of waste vial glass materials which are available from local hospitals as partial replacement of fine aggregate will reduce the cost of concrete. By using waste glass in concrete, wastage of glass can be reduced and also the environmental problems arise due to waste glass disposal are minimized. There are six varieties of mixes of concrete which have one control mix and other mixes consists of consists of 15% of medical vial waste with the different Bacteria concentration of 103, 105, 107, 109 and 1011 cells/ml of water were casted to get the optimum mix which bears the maximum load and has maximum healing capacity. Finally the results shows that the mix consist of 15% of medical vial waste with the Bacteria concentration of 107 cells/ml of water gives an improved properties in concrete and gave solutions to environmental and ecological problems and cost effective too.

Introduction Nowadays the major problem faced in the construction industry is the demand for the river sand. Due to the increase in the production for concrete, then the price for the raw materials also will increase due to the demand for the material. Due to this the construction cost will increases. This can be overcome by usage of waste vial glass which is being dumped as a waste as a partial replacement for the fine aggregate. These vial glass will be made available from the local hospitals which can be treated and can be used for the replacement purpose. These vial glass can be added in the 5 to 25% range. In India, about 330,000 tons of bio medical waste which is 15% of total waste generated in India is generated. These disposals cause health effects to human. These * M.

vial glasses are used for the injection purpose for storage of medicine. At last at one stage these glasses are disposed and no further retreatment can be done so thereby it had be
