Analytical Formulas for Interfacial Transition Zone Properties.

January 1, 1997
Author(s)
Edward J. Garboczi, Dale P. Bentz
Two analytical results are presented that are of use to concrete material technologists. Using a model of concrete in which the aggregates are spherical, but with an arbitrary size distribution, a result from statistical geometry can be used to accureately

Benchmarking the Length Measurement Capabilities of the National Institute of Standards and Technology

January 1, 1997
Author(s)
Richard M. Silver, J Land, Jack A. Stone Jr., Ronald G. Dixson, Bryon S. Faust, James E. Potzick, Michael T. Postek, et al
A cross-section of measurements from the Precision Engineering Division within the National Institute of Standards and Technology is benchmarked against other leading National Measurement Institutes. We present a variety of length-related calibration

Calibration and Fabrication Facilities for Optical Surfaces

January 1, 1997
Author(s)
Theodore V. Vorburger, Christopher J. Evans, C Asmail
NIST has calibration facilities and research services available for characterization of optical surfaces and optical figuring and finishing. The calibration facilities are for measurement of optical scatter, figure, and surface finish, and the fabrication

Capillary Transport in Mortars and Concrete.

January 1, 1997
Author(s)
Chiara F. Ferraris, N S. Martys
Results are presented of a study concerning capillary transport of water in concretes and mortars as a function of water/cement ratio, sand size distribution, and curing. Our studies indicate that the capillary sorption (1) of water in concrete exhibits a
