Kinetics of Reaction of Calcium Hydroxide and Fly Ash

August 1, 2001
Author(s)
Joseph J. Biernacki, P J. Williams, Paul E. Stutzman
The alkali activated reaction kinetics of a type-F fly ash with calcium hydroxide (CH) and water has been investigated at temperatures between 25 and 60 C. Thermogravimetric analysis (TGA) was used to determine CH consumption and production of hydrates

Measured Performance of Building Integrated Photovoltaic Panels

August 1, 2001
Author(s)
Arthur H. Fanney, Brian P. Dougherty, Mark W. Davis
The photovoltaic industry is experiencing rapid growth. Industry analysts project that photovoltaic sales will increase from their current $1.5 billion level to over $27 billion by 2020, representing an average growth rate of 25%.(Cook et al. 2000)[1]. To

Natural Ventilation Review and Plan for Design and Analysis Tools

August 1, 2001
Author(s)
Steven J. Emmerich, William S. Dols, James W. Axley
Natural ventilation has the potential to reduce first costs and operating costs for some commercial buildings while maintaining ventilation rates consistent with acceptable indoor air quality. While a recent surge of interest in Europe has advanced natural

This paper is a derivative of G2001-1392, Database-Assisted Wind Load Capacity Estimates for Low-Rise Steel Frames, by Jang, S., et al., intended for publication in the Journal of Structural Engineering.The original paper's abstract was:A comparative study

LADAR Sensing Applications for Construction

June 1, 2001
Author(s)
Geraldine S. Cheok, William C. Stone
One potential breakthrough technology that stands to revolutionize construction surveying and status monitoring is known as laser range imaging. The device used to obtain the field data is known as a LADAR (Laser Distance and Ranging). With LADAR it is

Physical and Chemical Aspects of Fire Suppression in Extraterrestrial Environments

May 22, 2001
Author(s)
Fumiaki Takahashi, Gregory T. Linteris, Vishwanath R. Katta
A fire, whether in a spacecraft or in occupied spaces on extraterrestrial bases, can lead to mission termination or loss of life. While the fire-safety record of US space missions has been excellent, the advent of longer duration missions to Mars, the moon

Trioxane-Air Counterflow Diffusion Flames in Normal and Microgravity

May 22, 2001
Author(s)
Gregory T. Linteris, M D. Rumminger, D L. Urban
Trioxane, a weakly bound polymer of formaldehyde (C3H6O3, melting point 61 deg C, boiling point 115 deg C), is a uniquely suited compound for studying material flammability. Like many of the more commonly used materials for such tests (e.g. delrin
