Soil Cement Shore Protection in Arctic Environment
Suitability of compacted and plastic soil cement prepared with sea water, for shore protection of islands in Arctic marine environment, is investigated. The laboratory test results indicate...
Seabed Strengthening in the Arctic by Deep Mixing
Improvement of soft soil sites in the Beaufort Sea would increase the versatility and usefulness of bottom-founded gravity structures for both mobile drilling units and permanent production...
Cement Grouting: Water Minimising Practices
Water gives cement grout its mobility, but the water needed for mobility exceeds hydration requirements substantially in most applications. If this excess water is allowed to collect and...
Use of Asphalt in Treatment of Dam Foundation Leakage, Stewartsville Dam
This paper presents the recent development and application of a hot asphalt grouting technique used to stop a 5,000 Imperial Gallons Per Minute (IGPM) (22,000 lpm) dam leakage under full...
Computer-Assisted Grouting Evaluation Systems
Electronic monitoring of cement pressure grouting at Ridgway Dam provides a powerful tool for geologic assessment of drilling and grouting results. Graphic surveillance and analysis of...
New Pavement from Old Concrete
Recycling portland cement concrete has gained momentum as an alternative to resurfacing aging highway and airfield pavements. Recycling cuts down rawmaterial requirements, reduces the...
Factors Influencing Zinc Cementation of Cadmium
The research reported here examines an innovative procedure for removal of cadmium from wastewaters. This process is the cementation of cadmium by zinc metal. Cementation is highly attractive...
Tensile Fracture and Fatigue of Cement Stabilized Soil
Portland cement stabilized soil is widely used as a base material for roads, airfields, and similar structures. Cracking in this material is studied using fracture mechanics concepts....
Tension-Compression Test of a Concrete Specimen Via a Structure Damage Theory
The concrete sample is assumed to consist of a large number of aggregates and cement paste. Their material properties are assumed to be perfectly elastic. The effective elastic property...
State of the Art in Concrete-Polymer Materials
Concrete-polymer materials represent a relatively new technology in the construction industry. In some cases polymers are combined with portland cement concrete and, in other cases, polymers...
Developments in New and Existing Materials
Materials engineering has emerged as an identifiable professional practice within civil engineering in the past few years. Although materials engineering is not new, the concept that this...
Structural Design, Cementitious Products, and Case Histories
The papers in this book represent deverse topics in structural engineering. In design of beam-columns by the AISC interaction equations, it is demonstrated that an inadequacy exists when...
Slurry Trenches for Containing Hazardous Wastes
Slurry trench technology has not advanced much during the past 10 years due to a lack in research and development, the excerbated litigious climate in the environmental protection field,...
Flowable Fly Ash: A New Cement Stabilized Backfill
Cement stabilized fly ash placed at a plastic fluid consistency is a new structural backfill material that flows into place, either above or below water, without using sophisticated construction...
Superplasticizers: Reducing Water in Concrete
Superplasticizers or high-range water reducers are new types of chemical admixtures which when incorporated into concrete can cause significant increases in its slump but without any loss...
Recent Developments in Pavement Skid Resistance
As pavements wear, they lose some of their skid resistance. This article discusses some of the leading options for restoring a pavement's skid resistance. The possibilities...
World's First All-Rollcrete Dam
Willow Creek Dam in Oregon will be the world's first concrete gravity dam designed specifically for and exclusively by roller compaction methods. The average in-place cost...
Fiber-Reinforced Concrete Proves Worth for Airport Pavements
Laboratory and field tests indicate that fiber-reinforced concrete has higher flexural and tensile strength, higher impact resistance, and improved resistance to spalling and joint deterioration...
Hazadous Wastes Should be Destroyed by Incineration�Not Stored in Landfills; Cement Kilns Could do the Job
Presently, it is common practice to place in landfills various hazardous wastes. Yet, say some experts, landfilling these wastes is a mistake. Landfilling is not final disposal, but merely...
New Uses For Soil-Cement
Since 1961, the use of soil-cement in energy and water resource projects has increased from 51,000 yd� to over 9,100,000 yd�. Its primary applications are erosion protection and seepage...
