Epoxy Repair of a Glulam Beam
The repair of timber structures by epoxy injection techniques is a recently developed repair alternative. Theoretical and experimental studies have resulted in the formulation of design...

Biggest Highway Rebuild
The reconstruction of the Wisconsin Interstate 90 and 94 involved 32 miles of 6-lane pavement. Most of the concrete aggregate for the job was recycled concrete pavement and all pavement...

KEMCOR—A Chemical and Corrosion Resistant Piping System
KEMCOR is a new underground composite pipe system designed for chemical process use in such industries which require a high degree of corrosion resistance to varying concentrations and...

Sensitivity Study of Composite Cylindrical Shells

Mechanics of Shear Failure in Epoxy-Jointed Concrete

Acoustic Emission and Birefringence Behavior of Epoxies

Epoxy-Repaired Concrete Walls Under Fire Exposure
The strength properties and other important parameters regarding the behavior of epoxy repaired concrete walls during fire exposure are experimentally determined. Both ASTM E-119 and the...

Composite Reinforced Fiber Glass Pipe

Temperature Effects on Epoxy Adhesives
The strength properties of structural epoxy adhesives at elevated temperatures is experimentally determined. Finite element analysis of thermal gradients in typical columns is provided....

Buckling Stresses of Stiffened Hyperboloidal Shells
Three hyperboloidal shell models made of epoxy resin (araldite) having nearly perfect geometry and constant wall thickness were tested first without stiffeners, afterwards with five, nine...

Creep of Coated Reinforcing Bars in Concrete
The creep properties of organic coated and uncoated No. 6 deformed steel reinforcing bars, embedded in concrete prisms, were measured for 2 yr with corresponding tensile stresses in the...

Behavior of Epoxy Repaired Full-Scale Timber Trusses
An experimental study has been conducted to determine the effectiveness of the epoxy repair method for full-scale timber trusses. A series of Pratt trusses (constructed of primarily new...

Epoxy Repair of Timber Roof Trusses
An epoxy injection repair project for timber roof trusses is described. Two 200-ft (61-m) trusses over four 50-ft (15.3-m) spans were visually inspected to select the weakest-appearing...

Epoxies — Miracle Materials Don't Always Give Miracle Results
In civil engineering applications, in the past 15 years epoxies have become widely used and have given excellent performance in floor surfacing, corrosion protection, repair of cracked...

Polymerization of Concrete Fights Cavitation
The techniques and materials used for the repair of concrete are many and varied. The repair at Dworshak Dam utilized epoxy resins, dry pack mortar, fibrous concrete and a new technique,...

Bond of Coated Reinforcing Bars in Concrete
The bond strengths were determined for 23 epoxy-coated (10 different epoxy coatings), six polyvinyl chloride-coated (three different coating materials), and five uncoated reinforcing bars....

Ventura City Hall Restoration
Describes the modernization of a concrete frame unreinforced masonry filler wall historical structure originally constructed in 1912. Newly developed and novel materials and procedures,...

Epoxy-Repaired Bolted Timber Connections
A major maintenance cost associated with timber construction is the repair of structural members in which checking, cracking, and splitting have occurred, in particular, near bolted joint...

Application of Epoxy Resins in Tunnel Lining Concrete Repair
Concrete lining in a large diameter tunnel spillway damaged by cavitation erosion caused by variable high flows up to 20,000 cfs was repaired by use of bonded concrete, and epoxy bonded...

Large Deflection of Rectangular Orthotropic Plates
