Sulfate Attack on Concrete Containing Fly Ash
The use of fly ash as a portland cement replacement in concrete may provide many technical and economic advantages. One such technical advantage is to improve the resistance of concrete...
Freezing and Thawing Durability of High Strength Silica Fume Concrete
Specimens from 27 batches of concrete with a water to cementitious (cement plus silica fume) ratio of 0.25 to 0.32, with and without entrained air, were tested for freeze-thaw durability...
Fatigue and Fracture Evaluation of Riveted Bridge Members
Among the major concerns of bridge engineers today are the fatigue damages that have been accumulated in riveted members and the safety of riveted structures. Many of these structures...
Fatigue Strength of Corroded Rolled Beams
Highway and railway bridges fabricated from ASTM A7, A36, and A572 steels will corrode if the paint system is allowed to fail for lack of maintenance. Corroding members lose cross section...
Fatigue Behavior of Steel Connection Angles
A method for predicting the fatigue behavior of flange angle elements is presented. The primary emphasis herein concerns an analytical approach for evaluating the fatigue life of flange...
Application of BEM to Two-Dimensional EPFM
This paper describes the authors' current and continuing research in application of the Boundary Element Method (BEM) to crack growth problems in Elastoplastic Fracture Mechanics...
Fiber Composite Materials in an Arctic Environment
This paper summarizes a study on the behavior of light-weight structural composite materials in cold environments. Results are presented for two composite materials: fiberglass-epoxy and...
Water Transport in Limestone by X-Ray CAT Scanning
The transport of water through the interior of Salem limestone test briquettes can be dynamically monitored by computer aided tomography (commonly called CAT scanning in medical diagnostics)....
Service Life of Underground Concrete Structures
The service life of underground concrete depends on both the physicochemical properties of the concrete materials and the properties of the in-service environment. The major factors controlling...
Fiberglas Reinforced Plastic Rebars in Lieu of Steel Rebars
Fiberglass reinforced plastics have recently been introduced in the market in the form of rebars for concrete reinforcement. The light weight, corrosion resistance and non-magnetic properties...
Surface Treatments for Concrete
The US Army Corps of Engineers initiated in 1984 a research program designated Repair, Evaluation, Maintenance, and Rehabilitation (REMR), one of the work units being the evaluation of...
Use of Copper Slag for Construction Purposes
Standard laboratory test results on the fine- and coarse-grained fractions of a copper slag have been presented. Based on the results of these tests, the possible use of the fine fraction...
Production of Masonry Blocks for Developing Countries
The need for nuturing of low cost building materials industry in developing countries has long been recognized throughout the world. costs of building materials. Therefore, construction...
Sprayed-On Polymer Mortar Construction
Sprayed-on polymer mortar has been used to construct low-cost, lightweight structures in a variety of locations. The addition of the two-component additive to one cubic yard of mortar...
Fatigue of Reinforcement in Partially Prestressed Beams
A summary of the findings of an extensive experimental program on the fatigue characteristics of partially prestressed concrete beams is described. It is observed that the stress range...
Fatigue Strength of Welded Steel Mesh
Welded steel mesh (WSM) is prefabricated by welding cold-drawn wires in a grid-like mesh. Engineers avoid using WSM as main reinforcement in highway structures due to their lack of knowledge...
Low-Cycle Fatigue Reliability of Offshore Structures Subjected to Earthquakes
This paper develops and implements a methodology for predicting probabilistically the damage an offshore structure will experience in an earthquake. The analysis begins with the probability...
Concrete Strength-Quality Assurance
