31. The Seventh Industrial Fluid Properties Simulation Challenge
Topic: Chemistry
Published: 10/8/2013
Authors: Riaz Ahmad, John K. Brennan, Kevin A Frankel, Jonathan D Moore, Joshua D Moore, Raymond Dale Mountain, Richard Ross, Vincent K Shen, Nathan E Schultz, Daniel W Siderius, Kenneth D Smith, Matthias Thommes
Abstract: The primary goal of the seventy industrial fluid properties simulation challenge was to test the ability of molecular simulation methods to predict the adsorption of organic adsorbates in zeolite materials. Zeoliet adsorbents are used in a variety o ...

32. Fluid Transport in High-Volume Fly Ash Mixtures with and without Internal Curing
Topic: Chemistry
Published: 10/7/2013
Authors: Igor de la Varga, Robert Spragg, Carmelo di Bella, Javier Castro, Dale P Bentz, Jason Weiss
Abstract: The transport of fluid and ions in concrete mixtures is central to many aspects of concrete deterioration. As a result, transport properties are frequently measured as an indication of the durability that a concrete mixture may be expected to have. T ...

33. A note on the critical enhancement of transport properties and correlation length of fluids
Topic: Chemistry
Published: 10/6/2013
Authors: Richard A Perkins, Jan Vincent Sengers
Abstract: The thermal conductivity and viscosity are known to exhibit an enhancement in fluids due to critical fluctuations. We have reviewed procedures proposed in the literature for estimating the correlation length determining the magnitude of these enhance ...

34. Influence of Sample Curing Conditions on Internal Curing Benefits Seen in Cementitious Materials
Topic: Chemistry
Published: 9/27/2013
Authors: Michael Golias, Dale P Bentz, Jason Weiss
Abstract: Internal curing uses pre-wetted fine lightweight aggregate (LWA) to supply cementitious systems with water. This increases the hydration of cement and reduces the influence of self-desiccation resulting in concrete with increased compressive strength ...

35. Best Practices Guide for High-Volume Fly Ash Concretes: Assuring Properties and Performance
Series: Technical Note (NIST TN)
Report Number: 1812
Topic: Chemistry
Published: 9/18/2013
Authors: Dale P Bentz, Chiara F Ferraris, Kenneth Alan Snyder
Abstract: A best practices guide is developed from a synthesis of recent research on high-volume fly ash (HVFA) concrete mixtures. These best practices can be applied by the concrete construction industry to achieve desired properties and ensure the (high) per ...

36. Viscosity Modifiers to Enhance Early Age Performance and Long Term Durability of Concrete
Topic: Chemistry
Published: 9/1/2013
Authors: Dale P Bentz, Kenneth Alan Snyder, Max A Peltz, K H Obla, Haejin Kim
Abstract: The service life distribution of concrete structures typically follows a ,bathtubŠ-shaped function, with a finite probability of early-age failures being followed by a life with a relative low probability of failure that ultimately increases dramatic ...

37. An Assessment of 25-Hydroxyvitamin D Measurements in Comparability Studies Conducted by the Vitamin D Metabolites Quality Assurance Program
Topic: Chemistry
Published: 8/12/2013
Authors: Mary Bedner, Katrice A Lippa, Susan Shu Cheng Tai
Abstract: Background: The National Institute of Standards and Technology (NIST), in collaboration with the National Institutes of Health Office of Dietary Supplements, established the first accuracy-based program for improving the comparability of vitamin D me ...

38. Sensors and Monitoring to Assess Grout and Vault Behavior for Performance Assessments
Topic: Chemistry
Published: 8/12/2013
Authors: Kenneth Alan Snyder, Jason Weiss
Abstract: To support performance assessment (PA) of waste vaults and grout monoliths, the National Institute of Standards and Technology (NIST) has performed a preliminary evaluation of the state-of-the-art of sensors, nondestructive evaluation methods, and an ...

39. Ternary Blends for Economical and Environmentally Friendly Concretes
Topic: Chemistry
Published: 7/31/2013
Authors: Dale P Bentz, Jussara Tanesi, Ahmad Ardani
Abstract: As sustainability moves to the forefront of trends in construction, concrete mixture proportions must be adjusted and adapted to a new set of economic and environmental demands. While high-volume fly ash concretes have been investigated extensively s ...
