Designing for Drama
Near the Passaic River in Newark, N.J., not far from the famous Iron Bound restaurant district and Newark's Penn Station, construction crews swarm around the steel skeleton...

A Primer on Micropiles
A major study of micropile technology has recently been funded by the Federal Highway Authority and completed by the authors. The subject is defined as a drilled and grouted, cast-in-place,...

Analysis of Glass-Ceramic Production from Lunar Resources
Two simulated regoliths were used to investigate the effects of processing and composition on the properties of lunar-derived glass-ceramics. For the simulant with moderate iron concentration,...

Tests of Full-Size Pretensioned AASHTO Beams with Debonded Strands
A summary of an experimental investigation dealing with the effects of strand debonding on the flexure and shear behavior of simply supported pretensioned AASHTO beams with a cast-in-place...

Evaluation of Cast Iron Columns for Safety and Reliability
Cast iron columns exist in numerous vintage buildings. Alterations to these buildings often require analysis and modification of the structural system. This paper identifies codes that...

Controlling Lead and Copper Corrosion and Sequestering of Iron and Manganese
With the recently enacted Lead and Copper Rule (LCR), many utilities are faced with the conflict of meeting the requirements of the Rule and controlling aesthetic problems caused by source...

The Relationship of Speciation to Iron and Manganese Removal Strategies
Case studies are presented describing how Fe and Mn speciation procedures were used to solve process problems at two water utilities. A series of filtration steps are used to separate...

Comparison of Biological and Chemical/Physical Iron Removal
The report compares the efficiency of chemical/physical and biological iron removal processes during the entire filter cycle. The results of the first three pilot studies performed in...

Recovery and Recycling of Copper from Wastewater using Iron Coated GAC
The purpose of this study was to prepare composite adsorbents that could be packed into a column and have adsorption characteristics similar to Fe oxide. This adsorbent was targeted to...

The Use of Iron Salts to Control Dissolved Sulfide in Districts' Trunk Sewers
Headspace H2S removal via the precipitation of dissolved sulfide was investigated using iron chlorides. Full-scale experiments were conducted in...

Analysis of Sand Movement on Noto Coast by Geochemical Method
The analysis of sand samples by X - ray fluorescent spectroscopy (abbreviated by XRF) gives the ratio of the geochemical elements to construct the sand samples. This shows the geochemical...

Restoring Freedom at the Capitol Dome
Early one morning last spring, a helicopter lifted that Statue of Freedom off its pedestal at the top of the U.S. Capitol Dome where it had stood undisturbed since shortly after the Civil...

The Use of Built-Up Compression Members—A Fabricator's Viewpoint
A variety of cross-sections of built-up compression members that have been used are shown. Suggested items that need to be addressed for the successful design and fabrication are discussed....

Cask Storage Verification Test—Full Scale Test
In Japan, the cask-storage method of spent fuel will be licensed in the near future and the related R&D works (partly of the Japanese Government have been carried out mainly by...

Structural Design on Ductile Iron Pipe
The thickness class designation for Ductile Iron pipe has been changed to a pressure class designation in the 1991 revision of the C150/A21.50 ANSI standard. However, the same conservative...

High-Performance Construction Materials and Systems
An Essential Program for America and Its Infrastructure—Executive Report
Prepared by American Concrete Institute; American Institute of Steel Construction; American Iron and Steel Institute; ASCE; Civil Engineering Research Foundation; Concrete Research and...

Design of Pena Colorada Tailings Retention Dam
This paper discusses the details involved in the design of a 66 meter high RCC dam to be used to create storage for slurry from an iron ore mining operation located near Manzanillo, Mexico....

Colorimetric Determination of Fe²+/Fe³+ Ratio in Radioactive Glasses

Evaluations of Glass Vitrification Techniques on Iron Ratio Determinations

Lunar Oxygen — The Reduction of Glass by Hydrogen
The direct reduction of volcanic glass by hydrogen has been proposed as a method of extracting oxygen from the lunar soil. Experiments using lunar simulant glasses reacted with flowing...
