Alfred Addai-Nimoh
About Candidate
I am Alfred and I am a Ph.D candidate who will be graduating in December of this year from Missouri S&T from the Civil Engineering Department.My Ph.D research has been on developing ultra high performance concrete for 3D printing applications and bridge deck overlays. As a result I have worked with and I am familiar with ASTM test methods for fresh, mechanical and durability properties of concrete. My research has gone deeper into studying the rheology of ultra high performance concrete at different scales and evaluating how different types of cement and SCM’s affect the rheology.One unique aspect about my research that makes me stand out is that the UHPC I developed has moved beyond the lab to being used to repair material for a real bridge. This experience I garnered has given me insight into what works on the field and thus what to think about when developing materials in the lab.My Ph.D. experience has given me the opportunity to work with organizations such as Missouri Department of Transportation and the US Army Corps of Engineers who have benefited from my research.
In addition to my core knowledge in concrete science, I possess other skills such as R&D project management, data analysis and presentation and proficiency in Revit
