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...
The Civil Engineering Foundation ? A New Beginning
The United States' construction industry is ailing, experiencing a decline that rivals that of the auto and other US manufacturing industries. How the decline is to be halted...
Suburban Superfund
Discovery of methane seeping into houses at a new development near Newark, Del. set off investigations that eventually led to the U.S. EPA declaring the site eligible for Superund cleanup...
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...
Ground Modification for a 14-Story Structure Over a Deep Peat Deposit
The foundation design and construction for a 14-story reinforced concrete office building northwest of Minneapolis is described. The building's geometry provided unusual foundation...
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...
Human Factors and Communication Problems in Foundation Engineering
Recent findings in non-engineering fields related to human factors are reviewed with emphasis on communication difficulties. Foundation engineering tasks are discussed in the context of...
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...
Fouling and Wood-Boring Communities Distribution on the Coast of Rio De Janeiro
The paper reports on a study of the dynamics of fouling communities and the distribution of wood-boring organisms along the coast of Rio de Janeiro, Brazil, which was motivated by the...
Sulfated Polysaccharides from Marine Invertebrates
The authors Laboratory is involved in the chemical and structural determination of sulfated polysaccharides from different sources. The main purpose of such studies is to compare these...
Managing a Megaproject
The tunnel beneath the English Channel is an unusual construction project because of the private sector financing of infrastructure as well as the price, $9 billion, and the international...
