Gap Analysis for Durability of Fiber Reinforced Polymer Composite in Civil Infrastructure
Prepared by the Civil Engineering Research Foundation. This report provides the results of a study on what is known and not known about the use of...
Closing in on Approval
A lack of qualification criteria and design standards has hindered some engineers from using fiber-reinforced polymers to restore concrete structures. But several organizations�among them,...
Quality Check
Composite materials, also known as fiber reinforced polymers (FRPs), have traditionally been reserved for aerospace engineering applications because of their high cost. FRPs'...
Emerging Materials for Civil Infrastructure
State of the Art
Prepared by the Emerging Materials Committee of the Materials Division of ASCE. This report presents a review of the state of the art on emerging materials...
Battling Concrete Corrosion
For decades engineers have fought concrete corrosion, but few methods have offered a long-term solution�until now. Electrochemical techniques such as electrochemical chloride extraction...
Glass Rebar's Growing Pain
Although engineers have used glass fiber reinforced polymer (GFRP) reinforcing bar in applications as diverse as winery roofs and bridge decks, a lack of standards and understanding by...
Finding the Right Bond
Professors and students from a Swiss university built a dual-span glass fiber reinforced polymer (FRP) bridge to gain a better understanding of how composite materials behave and how best...
Muscle Made of Carbon Fiber
Carbon fiber reinforced plastic (CFRP) extends service life and increases load-bearing capacity when applied to concrete structures. CFRP is less expensive than traditional strengthening...
Repeated Loading of Stabilized Recycled Aggregate Base Course
The fatigue behavior, resilient properties, and progressive accumulation of damage due to repeated flexural loads on a fiber-reinforced pavement base course material composed of cement-stabilized...
Better Salt Storage
Facing tighter maintenance budgets and stringent environmental regulations, many highway departments are designing and building innovative structures to store road salt. One such structure...
Journal of Composites for Construction
The Journal of Composites for Construction publishes original research papers, review papers, and case studies dealing with the use of fiber-reinforced composite materials in construction. Of special interest...
Catching Up on Composites
Until recently, Japan and Germany were way ahead of the U.S. in composite material technology for construction. Lighter, stronger and possibly more durable than conventional materials...
Dynamic Optimal Groundwater Remediation by Granular Activated Carbon
Objective functions to describe the operating and capital costs of GAC treatment are incorporated into a control theory model for optimal pump-and-treat groundwater remediation design....
Removal of Arsenic From Ground Water Using Granular Activated Carbon
Batch adsorption isotherm studies found that activated carbon (Hydrodarco, 14 X 40 mesh, American Norit) had removals of arsenic as high as 94% for a GAC dosage of 100 g/L and an initial...
Vapor Phase Biofiltration for Removal of VOCs
The selection of an appropriate packing material for the biofiltration process is an important factor in the removal of contaminants from vapor phase. This study evaluates two different...
Specification of Cu, Pb and Cr in Contaminated Sediment Effected by pH
Sediment was sampled from a contaminated river. Sequential extraction was applied to determine the speciations of Cu, Pb, and Cr in the sediment with varied pH (5?9), and the redox potential...
Climate Change: What the North American Water Engineer Should Know
Long-range forecasts of future global warming have been made based on the increase in carbon dioxide and trace gases in the air from human activities. Potential changes which would especially...
Simulating DBP Precursor Transport in Sacramento Delta
Fate and movement of disinfection by-product organic precursors in California's Sacramento-San Joaquin Delta was simulated for a 365-thy period with a hydrodynamics and transport...
New Construction Materials Proliferate in Japan
Research and development of new construction materials is extensive in Japan, and many new materials are being used in Japan now. The author analyzes the research environment in Japan,...
Large Deformation Theory Using Truncated Rotations
