Print Fidelity Metrics for Additive Manufacturing of Cement-based Materials

March 24, 2022
Author(s)
Edward Garboczi, Newell Moser, Joseph Biernacki, Hajar Afarani, Ebrahim Esfahani
Additively manufactured cement-based structures for infrastructure applications suffer from in-construction shape deformations, which are a strong function of process conditions and the rheology of the printing material (cement paste, mortar, or concrete)

Author(s)
N. Alan Heckert, Laura Mundy, Paul E. Stutzman
A new Standard Reference Material® (SRM) for portland cement clinker has been produced for the Office of Standard Reference Materials at the National Institute of Standards and Technology (NIST). The SRM clinkers are intended for use in developing and

Homogenization of Concrete Microstructures in Nuclear Power Plants

December 31, 2020
Author(s)
Christa Torrence, Aishwarya Baranikumar, Zachary Grasley, Edward Garboczi
Nearly all nuclear power plants in the United States are operating past their intended lifetimes or are requesting lifetime extensions, therefore understanding changes to the concrete containment structure over time is crucial to evaluate the structure's

Microstructure Homogenization of Concrete Used in Nuclear Power Plants
