Preparation of Simulants for Lunar Surface Materials

A Survey of Lunar Construction Techniques

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...

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....

Fiber Reinforced Plastic Grids for the Structural Reinforcement of Concrete
The use of fibre resin plastic grid is investigated as a primary bending reinforcement in concrete members. Laboratory bending data is compared with theoretical results using ACI 318-83...

MIIT; International In-Situ Testing of Simulated HLW Forms—Preliminary Analyses of SRL 165/TDS Waste Glass and Metal Systems
The first in-situ tests involving burial of simulated high-level waste (HLW) forms conducted in the United States were started on July 22, 1986. This effort, called the Materials Interface...

Magnetic Beneficiation of Highland and Hi-Ti Mare Soils: Rock, Mineral, and Glassy Components

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....

Some General Remarks on the Structural Behavior and Load-Extension Characteristics of Coated Fabrics with Special Reference to PTFE-Coated Glass-Fiber Fabric
The understanding of fabric behavior, and of coated fabrics in particular, is essential for the design and analysis of fabric structures. Although many research papers have been published...

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...

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...

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...

Lunar Resources: What is Known and Expected
The lunar regolith is the source of a number of basic materials which can be utilized in lunar construction. These materials include those which are obtained directly from the regolith...

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...

Utopia Under Glass
We stand within sight of the day when our reserves of fossils fuel will be inadequate to maintain the type of energy inefficient cities we have grown used to. This exercise in urban planning...

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...
