Microsilica (Silica Fume) Concrete Durability in Severe Environments
Microsilica (silica fume) concrete has provided increased durability in a variety of aggressive environments. Technical information is presented for microsilica concretes exposed to fire,...
Chloride Diffusion Constant for Concretes
Reinforced concrete exposed to chloride ions rapidly deteriorates once the chloride concentration level exceeds the corrosion threshold limit. The diffusion of the chloride ion through...
Use of Copper Slag for Construction Purposes
Standard laboratory test results on the fine- and coarse-grained fractions of a copper slag have been presented. Based on the results of these tests, the possible use of the fine fraction...
Coal Gas Legacy
The remains of a former coal gasiication plant were uncovered during redevelopment of a site for the new City Hall in Waterloo, Ont. The coal tar waste was a dense, immiscible tarry fluid...
What's Wrong With Superfund
In nine years of the federal government's Superfund program, $4 billion has been spent and only 38 of the 1,175 sites on the national priority list have been cleaned. There...
The Challenge of Yucca Mountain
Yucca Mountain is the most likely site for the nation's high level nuclear wastes. Congress chose the site out of three candidates for further study before designating it...
Fast Tracking Military Waste
The installation restoration program, the military version of Superfund, helped fast track the cleanup contracts for four military hazwaste sites located at Hanscom Air Field, Bedford,...
The Saga of Senate Bill 2067
With the advent of the California Superfund program, liability related to toxic waste cleanup became a critical issue in California. The state had no authority to indemnify consultants...
Accelerating Electrons
At a wastewater treatment plant in Miami, five scientists have pointed a 1.5 million v `e-beam' at pathogens and hazardous chemicals. It's the only full-scale...
The Model Cleanup
Standards for hazardous waste site cleanups may be inappropriate or inadequate to protect the public health. Civil engineers responsible for remediation decisions need to know about the...
High Hopes for Cattails
As other areas of wastewater treatment go high tech, man-made wetlands are treating wastewater from small towns and coal mines. Plants are grown in about 1 ft of water. Suspended solids...
Fracturing of Rock Using Expansive Soundless Chemical Demolition Agents
The theoretical principles of the action of expansive soundless chemical demolition agents are presented. The procedure for using these demolition agents are briefly outlined. Differences...
Chemically Induced Foundation Heave
The Kerr-McGee Electrolysis Plant in Henderson, Nevada has had recorded upward movements of portions of the building in excess of 18 inches. Contours of the measured heave indicate that...
Coastal Barrier Island Management in Florida
Coastal barriers in Florida have experienced the brunt of the state's rapid population growth. Excessive development of these environmentally sensitive areas has destroyed...
Dredge Disposal Monitoring by Fourier Shape Analysis
Fourier grain-shape analysis characterizes a population of sediments in terms of the shapes of the grains. The technique of grain-shape analysis has been successfully applied to the area...
Selection of Marine Bioindicators for Monitoring Radioactive Wastes Released from Nuclear Power Plants
