Waste marble powder

Abstract

Every manufacturing process generates waste. The amount of generated wastes increases as total production in every sector increases around the world. These wastes need to be managed somehow. Some byproducts and wastes can be utilized for using in construction sector and construction materials offer great potential about recycling wastes. For instance, 70% of marble block is wasted after quarrying and cutting and 40% of this waste becomes sludge. Recycling the generated wastes of marble industry in concrete production is an important aspect of both waste management and cleaner concrete production. The usability of waste marble dust in concrete and its effects on fresh concrete properties, hardened concrete properties and durability of concrete has been researched by various researchers. As a summary, it can be interpreted that waste marble dust usage with 5-20% replacement ratio in concrete can enhance the mechanical properties of concrete. Also, reuse of waste marble dust in concrete has environmental and economic benefits. Waste marble dust in concrete leads a reduction in cost and in carbon footprint of concrete. This chapter mainly focuses on the effects of waste marble dust in concrete on fresh concrete properties, hardened concrete properties, durability properties, environmental, and economic benefits. © 2022 Elsevier B.V., All rights reserved.
