Concrete Surface Treatments—A Selection Guide
Concrete deterioration can take many forms. The most common forms of concrete surface deterioration includes delaminations, spalling and scaling. This deterioration is usually caused by...

Coal Mine Waste Formation and Changes of Microstructure Under Artificial Salting

Effects of Freezing on Impact Properties of RTM Composites, and Their Applications in Offshore Structures
Resin transfer molding is rapidly being acknowledged as the process with potential to create perhaps the purest form of a composite material as representative of the concept of `material-by-design.'...

Sludge Dewatering in Freezing Beds
This paper summarizes the results of laboratory and pilot scale studies on the development of the sludge freezing bed. Laboratory studies indicated that a freezing bed could dewater up...

PS 5 Sewage Lagoon Embankment Stabilization
In 1981 an embankment containing a three-cell wastewater treatment lagoon was constructed adjacent to the northern edge of the Pump Station 5 gravel pad on the Trans Alaska Pipeline System....

Evolution of Ice Cover Roughness
The formation of an ice cover on a river results in an increase of stage relative to open water stages at the same discharge. Due to the formation process, especially for freeze-up ice...

Heat Exchange at the Ice/Water Interface on Flowing Water
Any time the water flowing under an ice cover has a temperature above freezing, there is an exchange of heat between the water and the ice. Earlier work by Ashton and others provided adequate...

Small-Scale Meteorology of Freezing Precipitation
Freezing rain and glazing are extremely disruptive to transportation, communication and power transmission. Local variations in the occurrence of freezing rain may be difficult to forecast....

Freezing Out Sludge
Sludge dewatering is one of the most difficult problems in water and wastewater treatment. This has been especially true for treatment plants in cold regions. Drying beds, the most common...

Creede, Colorado—Channel Rehabilitation
The existing grouted stone channel in Creede, Colorado, is approaching the end of its useful life. The channel is subjected to repeated freeze-thaw cycles causing spalling of the grout...

Effect of Fly Ash on the Microstructure and Durability of Concrete
The influence of fly ash on the microstructure and durability of concrete was investigated. It was found that the use of 50% fly ash in concrete reduced greatly its resistance to freezing-and-thawing...

Durability of High-Strength Concrete Containing Fly-Ash and Silica Fume
The durability of high-strength concrete made with local materials were tested with regard to the freezing and thawing resistance of concrete in accordance with ASTM C666 procedure A....

Effect of Environment on Durability of Pavement Materials: An Overview
The best known causes of material degradation in pavements include environment, traffic loads, and the use of substandard materials. Presented in the paper is a critical review of the...

Accurate Computation of Freezing Index
'Freezing index' (cumulative degree-days below freezing) is used for predicting frost penetration depths and modelling pavement performance. Contour maps which...

Cold Weather Concreting in the St. Paul-Minneapolis Area

Fire Hydrant Winter Maintenance Program for Anchorage

Pressure Buildup in Permafrost Pile Supports Induced by Freezeback

Influence of Ground Ice Variability on Settlement in Thawing Permafrost

Deep Frost Effects on a Longitudinal Edge Drain

Freezing and Thawing Durability of High Strength Silica Fume Concrete
Specimens from 27 batches of concrete with a water to cementitious (cement plus silica fume) ratio of 0.25 to 0.32, with and without entrained air, were tested for freeze-thaw durability...
