Edward Garboczi (Fed)

Dr. Edward J. Garboczi is a NIST Fellow in the Applied Chemicals and Materials Division of the Material Measurement Laboratory (MML) at the National Institute of Standards and Technology (NIST) in Boulder, Colorado. From 1988-2014, Dr. Garboczi worked in the NIST Inorganic Materials Group in the Engineering Laboratory, Gaithersburg, MD.

Dr. Garboczi's main research has been on the computational materials science of random composite materials, and especially of the computational materials science of concrete. This involves exploring relationships between microstructure and transport properties using realistic computer-based microstructural models and exact property calculation algorithms. Electrical, diffusion, and elastic properties, as well as fluid permeability, shrinkage, and A.C. electrical properties have been studied and found to be in quantitative agreement with experimental results. He has made extensive use of percolation and composite theory to understand numerical results. Much of his research has been built into the Virtual Cement and Concrete Testing Laboratory, a novel software package that used to optimize concrete using the power of the computational materials science of concrete. Dr. Garboczi has also extensively worked in applying finite element techniques to 3-D microstructure models of porous ceramics and polymer foams to accurately compute their linear elastic properties. Since 2001, he has used a novel combination of X-ray microcomputed tomography and spherical harmonic analysis to build quantitative mathematical models of random-shaped particles of cement, sand, gravel, fly ash, and slag, with applications by himself and others to lunar soil, chemical explosives, and concrete mix design. Dr. Garboczi applies particle shape to many powder problems, including additive manufacturing. Recently he has become interested in modeling atomic force microscopy and nanoindentation, studying the interrelation of surface topography and material heterogeneity.

Prior to coming to NIST in 1988, Dr. Garboczi was a research physicist at Armstrong World Industries, Inc. Research and Development Division, where he worked on the transport and mechanical properties of random porous building materials.

Dr. Garboczi received the Robert L' Hermite Medal from RILEM in 1992, a Silver Medal from the Department of Commerce in 2009, the 2009 Edward C. Henry award from the American Ceramic Society's Electronics Division, the 2012 Della Roy Lecture award from the American Ceramic Society's Cements Division, and the 2014 Robert E. Philleo award from the American Concrete Institute. He is a Fellow of both the American Ceramic Society and the American Concrete Institute, and a member of the American Physical Society.

Scanning Microwave Ellipsometer And Performing Scanning Microwave Ellipsometry

NIST Inventors

New strong, light, and compact formed carbon fiber components require shorter, higher-aspect ratio carbon fibers. Shorter carbon fibers must be aligned to realize the desired tensile strength. Before this invention, industry lacked a tool to characterize carbon fiber alignment for inline quality
