Investigation of Possible Usage of Electric Arc Furnace Dust in Cement Industry
Synopsis-In this research, possible usage of EAF dust on cement is investigated. Therefore, effects of addition of different percentages of EAF dust on the most important properties of cement such as hydration heat, water coefficient, viscosity, initial and final setting times, strength development and leachability of heavy metals were studied. Results showed that EAF dust alters the characteri...
متن کاملMaintenance Practices in Cement Industry
This paper analyzes an existing maintenance management system in a cement factory in the Kingdom of Saudi Arabia using a modified questionnaire. The analysis shows that there are strong areas such as predictive maintenance and maintenance automation. Other areas are found weak such as training programs and maintenance reporting. Some areas are found mix between strong and weak such as maintenan...
متن کاملCountervailing Power in the Icelandic Cement Industry
The Icelandic Competition Council recently ruled that a cement supplier with 75% market share did not enjoy a dominant position. The ruling was based on countervailing power of local concrete producers. To test whether there are economic arguments for the ruling, we present a simplified model of the industry and apply and adapt some recent work on bilateral oligopoly. We show that, in equilibri...

متن کاملDiagnosis of Mechanical Faults in Electric Motors
The ability to monitor the condition of an electrical machine has been a concern of industry for many years. Knowing when a machine requires maintenance allows users to perform the required maintenance at their convenience, rather than during costly unscheduled shutdowns. This need for improved industrial monitoring techniques has produced a number of studies on the detection of mechanical faul...
