Strain Rate Effects in Particulate-Filled Epoxy
In recent years it has been determined that a vast majority of solid materials display mechanical properties that are dependent on the rate of load application. There is the necessity...

Spillway Stilling Basin Repair Using Bonded Concrete and Epoxy Mortar

Gravity and Surface-Load Stresses in Spheres
Stresses due to gravity are reported for a solid sphere and for a hollow sphere with an inner diameter one-half its outer diameter. The stresses were obtained using the freezing method...

Yield and Failure of Glass-Epoxy Composites
Unidirectionally reinforced fibrous glass-epoxy composite specimens cut at angles 0° and 90° to the fiber axis were tested to failure under tension and compression at different temperatures...

Delayed Yielding of Three-Phase Epoxy Composites
A three-phase particulate composite, consisting of filler and voids within a matrix, was tested in compression up to yield under several constant strain rates. The volumetric filler and...

Technique for Study of Granular Materials
A technique is proposed for measuring characteristics related to the grain-pore distribution of granular deposits without disturbing the original granular structure. The technique consists...

Strengthening Rock by Injection of Chemical Grout
Chemical grout was injected into locally unstable areas in fractured granite in the North American Air Defense Underground Combat Operations Center (NORAD) near Colorado Springs, Colorado,...

Dynamic Loading of Several Concrete-Like Mixtures
An investigation was conducted to determine the static and dynamic properties of a group of potential structural materials consisting of conventional concrete, a mixture of cement and...

Photoelastic Analysis of Folded-Plate Structures
Two span folded plates with interior column and gable supports are studied by means of three dimensional photoelasticity. Small scale epoxy models fabricated from two commercially available...

Stresses in a Pressurized Cylinder with a Hole
The stresses in a long pressurized thin hollow cylinder capped at the ends, and with a circular hole far from the ends are experimentally determined. Brittle coating, mechanical and electrical...

Effect of Foreign Inclusions on Properties of Solids
Approximate expressions are given for the elastic properties of heterogeneous solids made of inclusions imbedded in a matrix with dissimilar properties and for the upper and lower limits...

Ultrasonic Evaluation of Reinforced Plastics
Bursts of ultrasound from 1.5 to 2.1 and of few microseconds duration were transmitted through unreinforced polyester and epoxy castings and through laminates of glass fiber reinforced...

Epoxy Resin for Structural Repair of Concrete Pavement
Results of tests performed in Laboratory of Corps of Engineers in formulating epoxy resins which will satisfactorily repair surface defects in portland cement concrete pavements, will...

Epoxy Asphalt Concrete for Airfield Pavements
Epoxy asphalt concrete is suited for heavy loads, high temperature and velocity blast, and fuel spillage; it is combination of graded mineral aggregate and EPON asphalt binder; conventional...

Epoxy Resin for Structural Repair of Concrete Pavement
Results of tests performed in Laboratory of Corps of Engineers in formulating epoxy resins which will satisfactorily repair surface defects in portland cement concrete pavements, will...

Epoxy Asphalt Concrete for Airfield Pavement
The author reviews epoxy asphalt concrete (EAC), a new type of paving material that addresses airfield pavement problems caused by the combined effects of heavy load, fuel spillage, and...
