Abstract
Typical Portland cement may contain up to 6 wt. % Fe2O3 as part of its chemistry. The iron content of the cement is important for maintaining the proper chemistry during the sintering of the cement. This paper will discuss the potential use of AMD treatment sludge for use in the manufacture of Portland cement. Important factors when considering the sludge chemistry will be presented. Logistics and handling issues will be discussed. The results of a preliminary assessment of the feasibility of this approach, including associated costs, will be presented.
Biography
Dr. Lykourgos Iordanidis is currently one the managers of the Chemistry Department at RJ Lee Group, Inc. Previously as a Senior Scientist at RJ Lee Group, Inc he was involved in the R&D of concrete additives and the development of analytical methods related to specific projects. Dr. Iordanidis’ initiation with the RJ Lee Group was in the sampling supervision, processing, interpretation and data presentation in the largest environmental study ever performed on a lower Manhattan building impacted by the collapse of the World Trade Center. Dr. Iordanidis holds a BS degree in Chemistry from the Aristotelian University of Thessaloniki, Greece and a PhD degree in Inorganic/Solid State Chemistry from Michigan State University. His post-doctoral studies took place at the University of Michigan. During his PhD thesis and postdoctoral studies his research involved several different classes of materials. He investigated the synthesis and characterization of relatively unknown semi-conducting bismuth chalcogenides for their potential as promising thermoelectric materials, as well as the synthesis and characterization of molecular compounds with potential anticancer activity and multimetallic clusters with redox properties. He has also conducted research in the area of porous and extended inorganic and organic solids. He has become experienced with a variety of X-ray diffraction, spectroscopic, thermal, microscopy and other materials characterization techniques.
