Vapor Hydration and Subsequent Leaching of Transuranic-Containing SRL and WV Glasses
High-level nuclear waste glass that is subject to disposal in the proposed unsaturated environment at Yucca Mountain, Nevada, initially will be altered through contact with humid air....
Recent Results on the Effect of Gamma Radiation on the Durability and Microstructure of DWPF Glass
The effect of gamma radiation on the durability and microstructure of a simulated nuclear waste glass from the Savannah River Site has been carefully investigated. Three large pieces of...
Volatilization of Cesium and Ruthenium From High-Level Waste Glass
The contamination of the air above high-level waste glass by 134Cs, 137Cs and 106Ru...
The DWPF Product, and Its Qualification Program
The Defense Waste Processing Facility (DWPF) at the Savannah River Site (SRS) will be the first facility in the nation capable of immobilizing high-level nuclear waste. Production of DWPF...
Aggregates, Fibers and Coupling Agent in Polyester PC
This study investigated the influence of fine aggregate, glass fiber and silane coupling agent on the mechanical and mode I fracture behavior of a polyester polymer concrete (PC). The...
Laboratory Fatigue Investigation of a GRP Bridge
A fatigue study of a 4.9 m glass-reinforced plastic bridge indicated a resistance to 1.6 million cycles of load without extensive damage to joints or elements. Viscoelastic creep occurred...
Bond Stress-Slip Relationships of FRP Rebars in Concrete
A newly developed type of reinforcement bar for concrete, Fiberglass Reinforced Plastic (FRP) rebar, can be used advantageously in concrete exposed to marine or corrosive environments....
Fatigue Behavior of Bond-Anchored Unidirectional Glass-FRP's
The contribution reports on the fatigue behavior of fiberglass reinforced plastic (FRP) bars, consisting of endless E-glass fibers embedded in a polyester (PE) matrix and anchored in a...
Flexural Strength of Externally Reinforced Concrete Beams
Results from tests of one rectangular and one T-beam are reported. The beams were strengthened by epoxy-bonding a 1/4 in. (6 mm) thick Glass Fiber Reinforced Plastic plate along the tension...
Bond Strength of Fiber Reinforced Plastic Bars in Concrete
In this study, 27 beam specimens were tested to determine the bond strength of fiber reinforced plastic bars (FRP) in tension. The specimens were reinforced with #4, #6, or #8 FRP bars....
A Seawall for Sea Mammals
With glass walls only 75 ft from Lake Michigan, an aquarium addition demanded solid seawall protection. Yes, in a strange twist of logic, the first step in creating a whale habitat for...
Effect of Temperature on the Load-Carrying Capacity of Fiber Glass Reinforced Plastic Beams
This paper describes an experimental investigation into the behavior of two T shaped beams made of fiber glass reinforcement and polyester or vinylester binders. Tests were performed at...
Application of Fiber-Composites in Civil Engineering
Two potential applications of Glass-Fiber-Reinforced-Plastics (GFRP) in civil engineering type structures are investigated: (1) GFRP rebars in concrete beams; (2) strengthening of concrete...
The Church on Stilts
Christ Church Cathedral is an Anglican church situated in the heart of downtown Montreal. Constructed in 1859, it is a perfect example of English neogothic architecture, characterized...
Using Borosilicate Glass as a HLW Storage Medium
There is growing concern over the quality of present high level waste management techniques. Instances of nuclear accidents and contamination at nuclear waste sites in the United States...
Instant Landmark
The 42 story curved glass facade of an $80 million structure at 17 State St. is destined to appear on the New York City postcards that show the tip of Manhattan Island. The site offers...
Suspended Polycarbonate Shield to Defeat Terrorist Threats
The Navy Civil Engineering Laboratory is conducting research on a window concept that offers great potential for overcoming the disadvantages of blast resistant windows. The concept is...
Strengthening of a Multi-Story Building with Deflection Constraints
Occasionally the existing structural or nonstructural systems of a building being strengthened require the imposition of deflection constraints or limits in order to avoid an undesirable...
Nonlinear Dynamic Response ofWindow Glass Plates Using Finite Difference Method
C. V. G. Vallabhan has established an efficient iterative procedure to solve the Von Karman nonlinear plate equations using finite difference method for a rectangular plate. Here the method...
Cladding Design for Tall Buildings
In the past twenty years, glass cladding has emerged as a popular and economic building material. Its use in tall buildings which are constructed in high-risk wind and seismic geographical...
