161. The Microstructure of Portland Cement-Based Materials: Computer Simulation and Percolation Theory
Published: 4/1/1998
Authors: Edward Joseph Garboczi, Dale P Bentz
Abstract: Cement-based materials are usually composites, where the matrix consists of cement paste. Cement paste is a material formed from the hydration reaction of cement, usually a calcium silicate material, with water. The microstructure of cement paste c ...

162. Cement Hydration in the Presence of Municipal Solid Waste Incineration of Fly Ash
Published: 3/1/1998
Authors: S J. Remond, Dale P Bentz, M. Pimpinella, J P Bournazel
Abstract: This study is part of a wider research program aimed at developing an assessment methodology of waste-containing concrete. This methodology is developed based on the study of mortars containing an experimental waste: MSWIFA (Municipal Solid Waste Inc ...

163. Concrete: A Multi-Scale Interactive Composite
Published: 3/1/1998
Authors: Edward Joseph Garboczi, Dale P Bentz
Abstract: Methods have been developed for predicting the overall diffusion coefficient of ions in concrete using a multi-scale interactive analysis, ignoring any chloride binding interactions. The analysis makes use of microstructure models of mortar/concret ...

164. Computational Materials Science on the Internet
Published: 12/1/1997
Authors: Dale P Bentz, Edward Joseph Garboczi
Abstract: The magazine article describes the background, motivation, and structure of the monograph, and how the monograph describes the computational materials science of concrete. Monograph is found on http://ciks.cbt.nist.gov/garboczi

165. 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 ...

166. Activation Energies of High-Volume Fly Ash Ternary Blends: Hydration and Setting
Published: Date unknown
Author: Dale P Bentz
Abstract: Because ready-mixed concrete is placed under a wide variety of environmental conditions, the influence of temperature on the hydration reactions and the accompanying setting (hardening) process is of critical importance. While contractors are general ...

167. Anticipating the Setting Time of High-Volume Fly Ash Concretes Using Electrical Measurements: Feasibility Studies Using Pastes
Published: Date unknown
Authors: Dale P Bentz, Kenneth Alan Snyder, Amzaray M Ahmed
Abstract: One common concern limiting the proliferation of high-volume fly ash (HVFA) concrete mixtures is the significant delay in setting that is sometimes encountered in field concrete mixtures. While several methods to mitigate the delayed setting times of ...

168. Measuring Freeze and Thaw Damage in Mortars Containing Deicing Salt Using a Low Temperature Longitudinal Guarded Comparative Calorimeter and Acoustic Emission (AE-LGCC)
Published: Date unknown
Authors: Yaghoob Farnam, Dale P Bentz, Aaron Richard Sakulich, Daniel Robert Flynn, Jason Weiss
Abstract: Deicing salts are often applied to the surface of pavements and bridge decks in the winter to melt ice; thereby improving safety for the travelling public. In this paper, the influence of NaCl deicing salt on freezing and thawing temperatures of pore ...
