Utilization of waste rubber tires in artificially cemented alluvial clay
AL-SUBARI, LUTF NAGI AHMED; Ekinci, Abdullah; Ferreira, Pedro Miguel Vaz; Sustainable Environment and Energy Systems (2022-7)
Problematic soils possess unfavorable engineering properties that need to be treated before usage, whilst cement is one of the most common materials used for such purpose. However, cement production is one of the highest contributors to global CO2 emissions that cause global warming. On the other hand, a massive amount of waste rubber tires is being generated annually, which commonly are being disposed of in landfills causing many environmental and health problems. In this context, this study investigates t...
Utilization of soda and beer wastes in cementitious systems
Aleessa Alam, Burhan; Yaman, İsmail Özgür; Department of Cement Engineering (2009)
To maintain the sustainability of cement and concrete production, there is a trend to use wastes in their production. Soda waste, generated by soda ash production process, and beer waste, generated by beer filtration process, are two locally produced wastes in Turkey and many other countries. The nature of these wastes, mostly their fineness, makes them possible to be used in concrete production, especially as a viscosity modifying agent in the self consolidating type of concrete. In this study, the additio...
Utilization of fly ash from fluidized bed combustion of a Turkish lignite in production of blended cements
Kürkçü, Mehmet; Selçuk, Nevin; Department of Chemical Engineering (2006)
Fly ashes generated from fluidized bed combustion of low calorific value, high ash content Turkish lignites are characterized by high content of acidic oxides, such as SiO2, Al2O3 and Fe2O3, varying in the range 50-70%. However, there exists no study for the investigation of the possibility of using these ashes as concrete admixture. Therefore, in this study, characterization of fly ashes from fluidized bed combustion of a Turkish lignite and evaluation of these fly ashes as a substitute for Portland cement...
