Virtual Testing of Cement and Concrete

May 10, 2006
Author(s)
Dale P. Bentz, Edward J. Garboczi, Jeffrey W. Bullard, Chiara F. Ferraris, Nicos Martys, Paul E. Stutzman
Concrete is a unique multi-phase, random, complex, and composite material that provides both strength and impermeability to engineered structures. Unlike most construction materials, the properties of concrete continue to develop over time and in place an

Using LADAR to characterize the 3-D shape of aggregates: Preliminary results

March 1, 2006
Author(s)
Edward J. Garboczi, Geraldine S. Cheok, William C. Stone
In previous publications, we have shown how using x-ray computed tomography to obtain the raw 3-D data for the coordinates of the surface, and then converting this raw data into an analytical function for the surface via an expansion in spherical harmonic

Shape Analysis of a Reference Cement

October 1, 2004
Author(s)
Edward J. Garboczi, Jeffrey W. Bullard
Recently, techniques for acquiring, analyzing, and using 3-D shape information for aggregates (sand, gravel) have been developed and demonstrated. These mathematical techniques, based on spherical harmonic coefficient analysis, have been applied to x-ray

Ultrasonic Evaluation Methods Applicable to Polymer Concrete Composites

April 1, 2003
Author(s)
A Garbacz, Edward Garboczi
Polymer composites (PC) appear as useful materials for repair and protection of building structures, as well as for manufacturing pre-cast elements. In the case of pre-cast elements as well as repair materials, the usefulness and durability of polymer
