Utilization of Coal Slurry Waste as an Alternative Raw ...

2017-6-15  It is a common knowledge that manufacturing of various construction raw materials such as lime and cement continuously increase the atmosphere emission of high concentration of carbon monoxide, sulphur oxides, nitrogen oxides etc. These toxic gases are one of the main reasons of air, water and soil pollution. In recent years, huge amount of solid wastes are recycled and used in various construction materials production as a result of environmental concerns. One of the types of these industrial pollutant solid wastes is coal slurry wastes. Coal slurry is the liquid coal waste and is produced by coal preparation and washing processes at coal enrichment plants. After mining process, coal is crushed and washed. The washing process generates large amounts of liquid and solid waste. There are lots of studies to utilize coal slurry in various industrial and building materials production. Because of consisting of high amount of clay minerals, using of coal slurry was frequently investigated in brick production as raw materials [2-5]. However, utilization of coal slurry in cement production was rarely researched and it was seen that literature and industrial studies for using in cement
