Abstract: Biomedical waste is being generating from hospitals, health clinics and laboratories. Disposal of this waste ash is in environmental concern, potentially lead to spread infectious diseases. In India, presently biomedical waste is generating 550.9 tons per day, and it is annually increasing by 8%. There is a scope of utilization of biomedical waste ash in the production of concrete. In this work, compressive strength, split tensile strength and durability of concrete with partial replacement of OPC with biomedical waste ash with different percentages (5%, 10%, 15% and 20%) and keeping Meta kaolin (20% constant were studied and the results were compared with that of control concrete by casting 30 concrete cubes and 25 cylinders. For durability study, concrete cubes were exposed to chloride attack (NaCl) and the results were compared with that of control concrete. Flexural behavior of reinforced concrete beams were also studied by using binder material with biomedical waste ash with Meta kaolin under different loading conditions and finally results were compared with that of ordinary Portland concrete beams.
Keywords: Biomedical Waste Ash, Metakaolin, Durability and Flexural Behavior.
Scope of the Article: Properties and Mechanics of Concrete
