Dale P. Bentz

Dale P. Bentz is a chemical engineer in the Inorganic Materials Group of the Materials and Structural Systems Division (MSSD) of the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST).

Mr. Bentz received his Bachelor of Science degree in May 1984 from the University of Maryland, College Park. Having worked in the Building Materials Division full-time during the summer of 1983 and part-time during the subsequent school year, he permanently joined the Division upon graduation. Mr. Bentz received a Master's Degree in Computer Science from Hood College in May 1991 and a Master's of Arts Degree in Teaching from Mount Saint Mary's University in 2013.

Initially, his research activities were focused on the development of computer image processing software and hardware to quantify the properties and degradation states of building materials. In 1987, he, along with three colleagues, received an IR-100 award from Research and Development magazine for the development of the Infrared Emission Surface Profilometer. More recently, his research has focused on the application of computer modeling to relate microstructure to material properties for random porous media, such as cement-based materials and fire resistive materials.

Mr. Bentz spent 17 months in industry (from July 1987 to December 1988) at the corporate research facility of W.R. Grace & Co., where he was the recipient of one patent, before returning to NIST. At W.R. Grace, his research and development efforts were directed towards waterproofing and fireproofing materials and admixtures for concrete. From 1993 to 1994, he spent six months working at the Centre Scientifique et Technique du Batiment in Grenoble, France, collaborating on research on the transport and shrinkage properties of building materials.

In 1997, he took a one-year leave of absence from his research position to volunteer at Nuestros Pequenos Hermanos, an orphanage in Mexico. In the summer of 2002, he took an eighteen-month leave to volunteer at Hogar de la Esperanza, an orphanage in Santa Cruz, Bolivia.

Mr. Bentz is a former chairperson of the Cements Division of the American Ceramic Society, a member of the American Society for Testing and Materials (ASTM), and a member of the American Concrete Institute (ACI). He is a recipient of the 1997 Brunaeur Best Paper Award from the Cements Division of the American Ceramic Society, the 1998 Robert L'Hermite Medal from RILEM, and a 1998 Bronze Medal Award from the U.S. Department of Commerce. In 1998, he was named a Maryland Distinguished Young Engineer. In both 1999 and 2000, he was a Knud Hojgaard Foundation visiting professor on concrete technology in the Building Materials Laboratory at the Technical University of Denmark.

In 2007, he was awarded the ACI Wason Medal for Materials Research for the paper "Mixture Proportioning for Internal Curing." That same year, Mr. Bentz was also selected as the recipient of the Frank G. Erskine award by the Expanded Shale, Clay, and Slate Institute for his research on internal curing.  In 2009, he was awarded a U.S. Department of Commerce Silver Medal Award (along with Jeffrey Bullard, Edward Garboczi, William George, Nicos Martys, and Judith Terrill) for research on developing capabilities to predict the performance of concrete. That same year, he and Dr. Kenneth Snyder were awarded a U.S. Department of Commerce Bronze Medal award for their research on developing a new class of concrete admixtures to slow diffusion in cement-based materials based on nanoscale viscosity modifiers.  He is also a recipient of the 2009 BFRL Communicator Award for the research that led to the development of the REACT web site (http://concrete.nist.gov/REACT.html).  In October 2011, he received the 2010 best paper award from the Magazine of Concrete Research.  In June 2012, he was awarded honorary membership in ASTM Committee C01 on Cement.
