Partial replacement of biomedical waste ASH in concrete

Abstract

Cement is a binder, a substance used for construction that sets, hardens and adhering to other materials, binding them together. Cement is seldom used on its own, but rather to bind sand and gravel together. Cement is used with fine aggregates to produce mortar for masonry, or with sand and gravel aggregates to produce concrete. Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement that hardens over time. Annual production of cement is nearly 425 million tonnes, India is the second largest cement producer in the world and accounts for 6.9 percent of worlds cement output. Biomedical waste, generated from medical sources and activities is a cause of concern for environmentalist. These wastes are generated in the process of diagnosis treatment and similar activities pertaining to human and animals. Also in the production or testing of biological instruments/components. Biological waste is broadly classified as biological and non-biological wastes that may or may not be infectious.
