DESCRIPTION:Materials Science and Engineering Seminar\n\nCasey Sundberg\n\n
 PhD Candidate\, Materials Science and Engineering\nMichigan Technological U
 niversity\n\n1–1:20 p.m.\n\nAbstract\n\nThis seminar discusses the high-tem
 perature plastic deformation characteristics of alkali activated cement (AA
 C). The AACs discussed in this seminar are inorganic sodium aluminosilicate
  polymers with an amorphous crosslinked network microstructure composed of 
 silicon and aluminum connected by oxygen bridges and sodium ions charge-bal
 ancing aluminum atoms. AACs can be used in place of portland cement in conc
 rete and have beneficial high-temperature properties. One benefit of AACs i
 s that they are plastic at high temperatures. This research posits that the
  high-temperature load-bearing capacity in the plastic region increases wit
 h increasing silica content due to an increase in oxygen bridge crosslinkin
 g. To determine if this is true hot compression tests were carried out on s
 amples with varying compositions\, and their viscosities were measured. Cha
 nges in crosslinking with composition were measured using solid-state nucle
 ar magnetic resonance spectroscopy. The changes in oxygen bridge crosslinki
 ng were then compared to changes in viscosity.\n\nBio\n\nCasey is a PhD can
 didate under the advisement of Dr. Sutter and Dr. Sanders. He is from Dulut
 h\, MN\, and received his BS in mechanical engineering in 2015 and his MS i
 n Civil Engineering in 2018\, both from the University of Minnesota Duluth.
  He is a member of various professional organizations\, including the Ameri
 can Concrete Institute where he has presented his previous research on AACs
  at four national conferences and is a member of several committees. He has
  also presented his previous work at a national conference of the American 
 Nuclear Society\, of which he is an Executive Committee member\, along with
  an accompanying conference proceedings paper. He has also taught Statics a
 nd Mechanics of Materials at UMD and has been a Researcher performing resea
 rch on other cement and concrete materials. He enjoys interdisciplinary col
 laboration\, but his primary focus is on materials science and engineering.
