Building for Environmental and Economic Sustainability (BEES) Online 2.1 Technical Manual

September 20, 2021
Author(s)
Joshua D. Kneifel, Anne Landfield Greig, Priya Lavappa, Brian Polidoro
Building stakeholders need practical metrics, data, and tools to support decisions related to sustainable building product selection. The Engineering Laboratory of the National Institute of Standards and Technology (NIST) has addressed this national need

Using fine sand shape metrics determined from X-ray microcomputed tomography to illustrate the influence of particle shape on the properties of dispersed mortars

July 10, 2021
Author(s)
Edward Garboczi, Jeffrey W. Bullard, Olafur Wallevik, Pierre Estephane
This study follows a first paper written on some three-dimensional geometrical quantities of a selection of sand particles from the United Arab Emirates (UAE), determined using a combination of X-ray microcomputed tomography (µCT) and spherical harmonic

Certification of Standard Reference Material(R) 2686b Portland Cement Clinker

April 12, 2021
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

December 31, 2020
Author(s)
Edward Garboczi, Christa Torrence, Zachary Grasley, Aishwarya Baranikumar, William Lawrimore
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

Designing 3D printable cementitious materials with gel-forming polymers

December 11, 2020
Author(s)
Edward Garboczi, Hajar Taheri Afarani, William carroll, Joseph J. Biernacki
Cement based pastes for 3D printing applications were prepared using hydrogel-forming polymers. Preliminary results suggest that such gel-forming polymers can reduce the need for more complex admixture packages as printing aids. The influence of polymer

EFFECTS OF PRE-STRAIN ON THE NON-LINEAR VISCOELASTIC PROPERTIES OF A MODEL SEALANT

November 18, 2020
Author(s)
Christopher C. White, Donald L. Hunston, Kar tean Tan
The non-linear viscoelastic properties of a model sealant were measured using stress relaxation tests conducted at different strain levels, x. Some specimens were measured with no previous strain history while others were given a preconditioning that

NIST NeXT: a system for truly simultaneous neutron and X-ray tomography

September 14, 2020
Author(s)
Jacob LaManna, Daniel S. Hussey, Victoria H. DiStefano, Eli Baltic, David L. Jacobson
Neutrons and X-rays provide excellent complementary, nondestructive probes to understand internal structure of systems across engineering and material science. With its sensitivity to hydrogen, neutrons excel at separating fluids, such as water or oil

Temperature-induced heteroaggregation in polydisperse portlandite suspensions

August 17, 2020
Author(s)
Edward Garboczi, Gaurav Sant, Iman Mehdipour, Narayanan Neithalath, Mathieu Bauchy, Samanvaya Srivastava, Sharu Bhagavathi Kandy
Temperature is well-known to affect the aggregation behavior of colloidal suspensions. This paper elucidates the temperature dependence of the rheology of portlandite (calcium hydroxide: Ca(OH)2) suspensions that feature a high ionic strength and a pH

Bayesian Hierarchical Models for Service Life Prediction of Polymers

August 5, 2020
Author(s)
Adam L. Pintar, Christopher C. White, Li Piin Sung
Service life prediction for polymers remains an elusive goal. In this chapter, a general methodology first described in a previous study \cite{pintar2018predicting} is recapitulated and extended. A central component of the methodology is a Bayesian

Penetration Loss at 60 GHz for Indoor-to-Indoor and Outdoor-to-Indoor Mobile Scenarios

July 8, 2020
Author(s)
Sung Yun Jun, Derek Caudill, Jack Chuang, Peter B. Papazian, Anuraag Bodi, Camillo Gentile, Jelena Senic, Nada T. Golmie
This paper investigates the penetration loss of an office building in indoor-to-indoor and outdoor-to-indoor mobile scenarios. The measurements were collected using our 60-GHz double- directional switched-antenna channel sounder. During measurement, the

Certification of Standard Reference Material(R) 1450e Fibrous Glass Board

April 17, 2020
Author(s)
Robert R. Zarr, Nathanael A. Heckert
Thermal conductivity measurements at and near room temperature are presented as the basis for certified values of thermal conductivity for SRM 1450e, Fibrous Glass Board. The meas-urements have been conducted in accordance with a randomized full factorial
