71. Comparison of Concrete Rheometers: International Tests at LCPC (Nantes, France) in October 2000
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6819
Published: 9/1/2001
Authors: L Brower, Chiara F Ferraris
Abstract: The aim of the present project was to compare measurements from the five types of concrete rheometers to provide data to establish correlations among them. As a matter of fact, differences between the various rheometers were expected, due to the comp ...

72. Sorptivity-Based Service Life Predictions for Concrete Pavements
Published: 9/1/2001
Authors: Dale P Bentz, M A Ehlen, Chiara F Ferraris, Edward Joseph Garboczi
Abstract: The degradation of concrete pavements is often controlled by the transport of a deleterious species (chloride or sulfate ions, or water in the case of freeze/thaw) into the concrete. With this in mind, a three-year research project, funded by the Fe ...

73. NIST Recommended Practice Guide: The Use of Nomenclature in Dispersion Science and Technology
Series: Special Publication (NIST SP)
Report Number: 960-3
Published: 8/1/2001
Authors: Vincent A Hackley, Chiara F Ferraris
Abstract: This Special Publication is essentially a reprint of two NIST Special Publications, SP 945 and SP 946. This particular Practice Guide provides guidelines for the use of technical and scientific nomenclature related to ceramic dispersions.The use of n ...

74. Concrete Mixing Methods and Concrete Mixers: State of the Art
Series: Journal of Research (NIST JRES)
Published: 4/1/2001
Author: Chiara F Ferraris
Abstract: The performance of concrete is determined by its microstructure. Its microstructure, in turn, is determined by its composition, its curing conditions, and also by the mixing method used to process the concrete. This paper gives an overview of the var ...

75. The Influence of Mineral Admixtures on the Rheology of Cement Paste and Concrete
Published: 2/1/2001
Authors: Chiara F Ferraris, K H Obla, R Hill
Abstract: Rheological tests on cement paste were used to successfully select the type and dosage of mineral admixtures that improved concrete workability. Among the six different mineral admixtures tested, the ultra fine fly ash (UFFA), was determined to give ...

76. Guide to Rheological Nomenclature: Measurement in Ceramic Particulate Systems
Series: Special Publication (NIST SP)
Report Number: 946
Published: 1/1/2001
Authors: Vincent A Hackley, Chiara F Ferraris
Abstract: This document provides definitions of terms and expressions relating to the measurement of rheological properties in liquid-based ceramic particulate systems (i.e., suspensions, pastes, and gels). The definitions are largely generic and should be com ...

77. Concrete Materials Database
Published: 12/1/2000
Authors: C B Oland, Chiara F Ferraris
Abstract: ACI Committee 126 on Database Formats for Concrete Materials Properties was organized in 1990 to develop and report information on database formats for concrete and related materials. The committee is accomplishing this mission by preparing guides f ...

78. Workability of Self-Compacting Concrete
Published: 12/1/2000
Authors: Chiara F Ferraris, L Brower, C H Ozyildirim, J A Daczko
Abstract: The slump test is widely used to evaluate the workability of Concrete. However it has serious drawbacks, especially for self-compacting concrete (SCC). Other flow characteristics such as viscosity or filling capacity or time of flow through an ori ...

79. User's Guide to the NIST Virtual Cement and Concrete Testing Laboratory. Version 1.0
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6583
Published: 11/1/2000
Authors: Jeffrey W Bullard, Chiara F Ferraris, Edward Joseph Garboczi, Nicos Martys, Paul E Stutzman
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 ...

80. Using Impedance Spectroscopy to Assess the Viability of the Rapid Chloride Test for Determining Concrete Conductivity
Series: Journal of Research (NIST JRES)
Published: 7/1/2000
Authors: Kenneth Alan Snyder, Chiara F Ferraris, Nicos Martys, Edward Joseph Garboczi
Abstract: The suitability of using the initial current from the rapid chloride test (ASTM C 1202) to determine specimen conductivity is tested using impedance spectroscopy with a frequency spectrum of 10 Hz to 1 MHz. The specimen conductivity has an analytica ...
