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
