1. User's Guide to the NIST Virtual Cement and Concrete Testing Laboratory. Version 1.0 (NISTIR 6583)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6583
Published: 11/1/2000
Authors: Dale P Bentz, Glenn P Forney
Abstract: This NISTIR serves as the user's manual for Version 1.0 of the Virtual Cement and Concrete Testing Laboratory (VCCTL). Using the VCCTL, a user may create starting microstructures of cement (gypsum, fly ash, etc.) particles in water, hydrate the micr ...

2. A Comparison Study of Portland Cement Hydration Kinetics as Measured by Chemical Shrinkage and Isothermal Calorimetry
Published: 5/1/2013
Authors: Xueyu Pang, Dale P Bentz, Christian Meyer, Gary Funkhouser, Robert Darbe
Abstract: Two different methods of evaluating cement hydration kinetics, namely chemical shrinkage and isothermal calorimetry tests, are used to investigate the early stage hydration of different classes of oilwell cement at various temperatures. For a given c ...

3. A Computer Model to Predict the Surface Temperature and Time-of-Wetness of Concrete Pavements and Bridge Decks
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6551
Published: 8/1/2000
Author: Dale P Bentz
Abstract: This report provides documentation and example results for a computer model developed to predict the surface temperature and time-of-wetness (and time-of-freezing) of concrete pavements and bridge decks. The model is based on a one-dimensional finite ...

4. A Dual Concentric Ring Test for Evaluating Residual Stress Development Due of Restrained Volume Change
Published: 9/1/2010
Authors: John Schlitter, Andrew Senter, Dale P Bentz, Tommy Nantung, Jason Weiss
Abstract: The standard restrained ring test (ASTM 1581-04) is a simple, economical method to evaluate a concrete mixture s susceptibility of shrinkage cracking. Unfortunately, the test only provides restraint against samples that shrink and can not be used to ...

5. A Hard Core/Soft Shell Microstructural Model for Studying Percolation and Transport in Three-Dimensional Composite Media
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6265
Published: 1/1/1999
Authors: Dale P Bentz, Edward Joseph Garboczi, Kenneth Alan Snyder
Abstract: This user's manual provides documentation and computer program listings for the three-dimensional hard core/soft shell microstructure model developed at the National Institute of Standards and Technology. The model has been developed to represent th ...

6. A Materials Science-Based Approach to Characterizing Fire Resistive Materials
Published: 4/9/2009
Authors: Dale P Bentz, Christopher C White, Kuldeep R Prasad, Daniel Robert Flynn, Donald Lee Hunston, Kar T. Tan
Abstract: While ASTM E119-07a is commonly employed to establish a fire rating for a fire resistive material (FRM)/steel assembly, the test method provides little quantitative information on either the thermophysical or adhesion properties of the FRM, beyond in ...

7. A Stokes Permeability Solver for Three-Dimensional Porous Media
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7416
Published: 4/4/2007
Authors: Dale P Bentz, Nicos Martys
Abstract: A set of C and Fortran computer programs have been developed for computing the permeability of three-dimensional porous media under incompressible Stokes flow conditions. In this NISTIR, the background for developing these codes is reviewed and the ...

8. ADVANCES IN PORE STRUCTURE CHARACTERIZATION AND PERFORMANCE PREDICTION OF PERVIOUS CONCRETES
Published: 5/3/2010
Authors: Narayanan Neithalath, Dale P Bentz, Milani S Sumanasooriya
Abstract: Pervious concrete is receiving renewed interest as a sustainable construction material for parking lots, sidewalks, and low-traffic-volume roads. A key characteristic of this material is its coarse porosity, achieved by omitting the fine aggregates ...

9. Accelerated and Natural Carbonation of Concretes with Internal Curing and Shrinkage/Viscosity Modifiers
Published: 1/5/2014
Authors: Alejandro Duran-Herrera, Jose Manuel Mendoza-Rangel, Edgar de los Santos Rodriguez, Francisco Vazquez, P Valdez, Dale P Bentz
Abstract: In many parts of the world, corrosion of reinforcing steel in concrete induced by carbonation of the concrete continues to be a major durability concern. This paper investigates the accelerated and natural carbonation resistance of a set of 7 concret ...

10. Acoustic Emission and Low Temperature Calorimetry Study of Freeze and Thaw Behavior in Cementitious Materials Exposed to NaCl Salt
Published: Date unknown
Authors: Yaghoob Farnam, Dale P Bentz, Allison Hampton, Jason Weiss
Abstract: This paper describes a series of experiments that were performed to assess the freeze-thaw behavior of mortar samples exposed to NaCl solutions. A low-temperature longitudinal guarded comparative calorimeter was used to perform cyclic freeze-thaw te ...
