Aerogel?A Transparent, Porous Superinsulator
Silica aerogel is an unusual, transparent, low density, thermally insulating solid useful for a variety of applications. We have been investigating silica aerogel for use in transparent...
Implementation of Material Requirements in Specifications
This paper focuses on where to find information on materials, their compatibility, minimum standards and specifying of materials and their use. The paper also presents case histories on...
Composites Performance in the Infrastructure
Fiberglass reinforced plastics (FRP) composites have been used in demanding structural applications, mostly for special corrosion resistant construction products, for several decades....
Unidirected Twined-Strand Composites and Their Uses
Twined strand composites are a new class of unidirected continuous-fiber-reinforced composite materials where the orientation of the continuous fibers is a twine of unidirected helically...
Nonprestressed and Prestressed FRP Sheets as External Reinforcement of Wood Members
The paper presents a summary of an analytical and experimental investigation of a new form of wood construction involving external bonding of thin fiber reinforced plastic (FRP) sheets...
Evaluation of Partial Depth Spall Repair Materials and Procedures
In 1990, as a part of a Strategic Highway Research Program project (SHRP H-106, Innovative Materials Development and Testing), an investigation was initiated to evaluate the performance...
Seattle Plays It Safe
To ensure the reliability of its aging water system in a major earthquake, the Seattle Water Department commissioned a comprehensive assessment of the system's seismic reliability...
Dallas Goes Trenchless
Dallas Water Utilities (DWU) has stopped relying solely on traditional open-cut trenching methods. Instead, we look to trenchless technologies to minimize costs and disruption to the public....

Effects of Freezing on Impact Properties of RTM Composites, and Their Applications in Offshore Structures
Resin transfer molding is rapidly being acknowledged as the process with potential to create perhaps the purest form of a composite material as representative of the concept of `material-by-design.'...
Internationalization of Engineering Professions
The most salient features impacting the development of our deepwater frontier areas are considered. The areas of higher potential for deepwater reserves are identified. The integrated...

Utilization of Waste Materials in Civil Engineering Construction
Industrial growth has increased the volume of wastes generated from energy production, mining, industrial processes and civil works. For economic and related reasons, the use of waste...
RCC at 10
Tens years after the first roller-compacted concrete (RCC) dam in the U.S.�the 169 ft high Willow Creek Dam in Oregon�was completed, the method has gained wide acceptance around the world...
Instrumenting the `Y'
Segmental bridges are still relatively new to the U.S. and questions persist about their design and behavior. To expand the knowledge base, a number of laboratory and field studies have...
Put to the Test
In the construction industry, the concept of life-cycle cost applies not only to the infrastructure itself, but to the materials that go in to building that infrastructure. To improve...
Settling Down Easy
In order to more fully participate in the international and Asian Pacific aviation network, it was decided to establish a highly efficient 24-hour a day operation at the New Kansai International...
Underground Research: Here and There
Geotechnical research in Europe, Japan and the U.S. were compared in a study funded by the National Science Foundation. Visits to research facilities and several surveys resulted in two...
Rethinking the Competitive Bid
Concern that the U.S. construction industry is losing its competitive edge is nothing new. Ironically, the problem is not so much rooted in foreign technical expertise as it is in our...
Dome Over Orlando
The article describes Orlando's new City Hall, a 267,000 sq ft nine-story reinforced concrete tower, clad in granite-aggregate precast concrete panels and topped by a 120...
