Creep of Coated Reinforcing Bars in Concrete
The creep properties of organic coated and uncoated No. 6 deformed steel reinforcing bars, embedded in concrete prisms, were measured for 2 yr with corresponding tensile stresses in the...

Physical Model for Steel Corrosion in Concrete Sea Structures—Application
The theoretical physical model developed in a companion paper, is applied to a simplified calculation of corrosion rates and times to corrosion cracking of concrete cover. Setting up approximate...

Energy for Production of Consumable Materials
Energy requirements were determined for the production of the following consumable materials used in various water and wastewater treatment operations: activated carbon, alum, ammonium...

Direct Injection of Reclaimed Water Into an Aquifer
The changes in water quality that occur when reclaimed water is injected into a confined aquifer are being studied. The major objectives are: (1)To determine the quality changes; (2)to...

Counteracting Chloride-Induced Damage to Bridge Decks with Latex and Plastic
Salt used to control ice causes deterioration of reinforced concrete bridge decks, but recent developments, though still somewhat expensive, can prevent deterioration of existing decks....

Quality Control of Thermoplastic Waterstop Joints
A method of selecting, specifying, and inspecting polyvinyl chloride waterstop joints in concrete hydraulic structures to assure quality control under a zero-defects welded-joint concept...

Tunnel Sealing Method with Waterproofed PVC Sheets
A modern method of tunnel sealing with plastic waterproof polyvinyl chloride sheets for tunnels and all kinds of underground constructions is presented. Using the heating wedge manual...

Tunnel and Shaft Sealing Methods Using Polyvinyl Chloride Sheet
This report decribes a newly developed sealing method for tunnels and shafts showing many advantages, such as the possibility of sealing on a wet and rough surface and the tight fixation...

Bond of Coated Reinforcing Bars in Concrete
The bond strengths were determined for 23 epoxy-coated (10 different epoxy coatings), six polyvinyl chloride-coated (three different coating materials), and five uncoated reinforcing bars....

Effect of Catalyst in Soil-Resin Stabilization
With the soil-resin stabilized samples, experimental curves are obtained showing how unconfined compressive strengths are related to percent stabilizer at different temperatures with different...

Water Pollution and Associated Effects from Street Saltation
The bare pavement policy has resulted in a great increase in the use of deicing salts. They are more efficient and economical than abrasives. However, there is excessive application leading...

Removal of Lignin from Water by Precipitate Flotation
Flotation was effective for the removal of lignin from aqueous solution when alum (aluminum sulfate) was used as a precipitator and a cationic surface-active agent, such as a quarternary...

Water Quality Models Using the Box-Jenkins Method
The Box-Jenkins method, a time-based technique for time series analysis, is shown to be successful in modeling chloride and dissolved oxygen data for the St. Clair River near Corunna,...

Weather Modification for Use in High Plains
The users decision process on whether or not to utilize weather modification is not the same as the decision process involved in a scientific experiment. A decision to use weather modification...

Competitive Growth of Sewage Organisms
A Warburg study demonstrates the effects of low temperature, chloride ion concentration, and ultraviolet irradiated asphalt on the growth of activated sludge and sewage fungus Geotrichum...
