Durability of Flax FRPs Exposed to Accelerated Environmental Conditions
It is well known that synthetic fiber reinforcements, such as glass fibers, elevate the mechanical properties of polymer materials. Considering the synthetic material’s renewability challenges, natural fibers, such as flax ... -
The effect of different dewatering techniques on resulting effluent particle size.
A paucity of literature has compared geotextile dewatering methods to more conventional dewatering methods (i.e. centrifuge, sedimentation) in the context of how geotextile dewatering performs at reducing particulate matter ... -
Effect of Fiber Orientation on Nonlinear Behavior of CFRP Composites
Fiber orientation is one of the important parameters that affect strength and ductility of FRP-confined concrete columns. A number of studies have been conducted on various fiber orientations and wrap thicknesses, but have ... -
THE EFFECT OF FREEZE/THAW CYCLES ON THE PERFORMANCE AND MICROSTRUCTURE OF CEMENT-TREATED SOILS
In this paper, the performance and structural changes in cement-treated soils under influence of freeze/thaw (f/t) exposure are investigated. Specimens from plastic and compacted soil-cement mix designs were exposed to ... -
Effects of long shredded rubber particles recycled from waste tires on mechanical properties of concrete
The goal of this research is to study the mechanical properties of recycled rubber particles extracted from scrap tires in concrete to introduce a sustainable waste management system and subsequently to reduce the use of ... -
Enhancing the Interface Friction between Glass Fiber-Reinforced Polymer Sheets and Sandy Soils through Sand Coating
Soil-pile interface friction is an important geotechnical engineering factor to be considered in achieving a safe, cost-effective design. Conventional construction materials such as concrete, steel, and wood exhibit serious ... -
Evaluating Impact Resonance Testing as a Tool for Predicting Hydraulic Conductivity and Strength Changes in Cement-Stabilized Soils
In this paper the impact resonance (IR) test method is used as a nondestructive tool to examine the curing progression, freeze/thaw (f/t) resistance, and healing potential of cement-stabilized soils. Resonant frequency ... -
Evaluating the movement of dissolved porewater species through a marine sediment 51 years after establishment of a pulp and paper effluent stabilization basin
Over 50 years ago, a marine estuary was converted to a wastewater stabilization basin for treatment of primarily pulp and paper effluent. As a result, the basin was immediately converted to a “freshwater” environment and ... -
Examining freeze/thaw cycling and its impact on the hydrualic conductivity of cement-treated silty sand
Cement-based solidification/stabilization (s/s) is a remediation technology that has been widely used for treatment of a range of contaminants. Currently there is limited published data on changes in hydraulic performance ... -
Examining metal migration through geotextiles during dewatering
This paper presents a study conducted to assess the influence that a filter cake deposited on the surface of the geotextile has on the mobility of three metals (Cu, Pb, Zn) during filtration of a contaminated sediment. Two ... -
Examining the Ultraviolet Optical Screening Tool as a Viable Means for Delineating a Contaminated Organic Sediment
Rapid and accurate delineation of contaminated sediments in marine environments is critical for the effective assessment of site risks and the development of appropriate remedial action plans. In this study, a new application ... -
Experimental and Analytical Behavior of Sandwich Composite Beams: Comparison of Natural and Synthetic Materials
In this study, the flexural behavior of sandwich composite beams made of fiber-reinforced polymer (FRP) skins and light-weight cores are studied. The focus is on the comparison of natural and synthetic fiber and core ... -
