1. Modeling and Measuring Chloride Ingress into Cracked Mortar
Published: 8/8/2016
Authors: Scott Z Jones, Jeffery Davis, John L Molloy, John R Sieber, Dale P Bentz
Abstract: Chloride ingress into reinforced concrete structures is responsible for initiating corrosion of steel embedded into concrete. To aide in the prediction of concrete service life, a chloride ingress model that includes chloride binding to the cemen ...

2. Chloride Diffusivity in Hardened Cement Paste from Microscale Analyses and Accounting for Binding Effects
Published: 8/5/2016
Authors: Pietro Carrara, Laura De Lorenzis, Dale P Bentz
Abstract: We study the diffusion of chloride ions in hardened cement paste (HCP) under steady-state conditions and accounting for the highly heterogenous nature of the material. The HCP microstructures are obtained through segmentation of X-ray images of r ...

3. On the Relation of Setting and Early-Age Strength Development to Porosity and Hydration in Cement-Based Materials
Published: 2/10/2016
Authors: Didier Lootens, Dale P Bentz
Abstract: Previous research has demonstrated a linear relationship between compressive strength (mortar cubes and concrete cylinders) and cumulative heat release normalized per unit volume of (mixing) water for a wide variety of cement-based mixtures at ages o ...

4. Minimizing Paste Content in Concrete Using Limestone Powders ‹ Demonstration Mixtures
Series: Technical Note (NIST TN)
Report Number: 1906
Published: 1/14/2016
Authors: Dale P Bentz, Scott Z Jones, Didier Lootens
Abstract: In recent years, there has been great interest in reducing the cement content of concrete, due to the high energy and carbon dioxide footprints of cement production. There are numerous (waste) materials that can be substituted for cement in the c ...

5. Comparative study of methods to measure the density of Cementitious powders
Published: 12/14/2015
Authors: Michelle Annette Helsel, Chiara F Ferraris, Dale P Bentz
Abstract: The accurate measurement of the density of hydraulic cement plays an essential role in the determination of concrete mixture proportions. As more supplementary cementitious materials (SCM), such as fly ash and slag, or cement replacement materials, ...

6. Effect of the Interface Moisture Content on the Bond Performance between a Concrete Substrate and a Non-Shrink Cement-Based Grout
Published: 12/10/2015
Authors: Igor de la Varga, Jose Munoz, Dale P Bentz, Benjamin Graybeal
Abstract: Prefabricated Bridge Element and System (PBES) construction commonly relies on field-cast grout-type materials to complete the connections between precast concrete elements. The interface bond between the grout and the substrate concrete can be a key ...

7. Effect of a micro-copolymer addition on the thermal conductivity of fly ash mortars
Published: 11/5/2015
Authors: Alejandro Duran-Herrera, Joana Ketterine Campos-Dimas, P Valdez, Dale P Bentz
Abstract: In this study, a copolymer composed of hollow spherical particles with an average particle size of 90 µm was evaluated as a lightweight aggregate in Portland cement-fly ash mortars to improve the thermal conductivity (k) of the composite. Mortars wer ...

8. Mitigation of autogenous shrinkage in repair mortars via internal curing
Published: 10/22/2015
Authors: Dale P Bentz, Scott Z Jones, Max A Peltz, Paul E Stutzman
Abstract: Repair mortars are being used with increasing frequency to maintain the aging US infrastructure. Durability is a key concern for such repair materials and both their volume stability and bond to the existing concrete are key attributes, the forme ...

9. Numerical Simulation of Heat and Mass Transport during Hydration of Portland Cement Mortar in Semi-adiabatic and Steam Curing Conditions
Published: 10/22/2015
Authors: Emilio Hernandez-Bautista, Dale P Bentz, Sadoth Sandoval-Torres, Prisciiano Cano Barrita
Abstract: The mass and heat transport during steam curing of concrete has a bearing on both the mechanical and durability properties. Therefore, it is essential to take into account the temperature evolution and the moisture distribution to prevent premature d ...

10. Influence of Internal Curing on Properties and Performance of Cement-Based Repair Materials
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 8076
Published: 10/6/2015
Authors: Dale P Bentz, Scott Z Jones, Max A Peltz, Paul E Stutzman
Abstract: Repair materials are playing an increasingly important role in the maintenance of our nation‰s aging infrastructure. Understanding their properties and performance is critical to planning and executing appropriate repairs that will provide the re ...
