Durability of Concrete Beams with Bonded FRP Composites made of Flax and Glass Fibers
Synthetic fibers, such as glass fibers, in the form of fiber-reinforced polymer (FRP) composites have been extensively used for the repair and strengthening of existing concrete structures in the past three decades. As ... -
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 ... -
Geotextile biofiltration of primary treated municipal wastewater under simulated artic summer conditions.
Wastewater stabilization ponds (WSPs) are common for wastewater treatment in remote Canadian Arctic communities. In this paper, two geotextiles of different mass/unit areas are examined as a potential biofiltration upgrade ... -
An Analytical Approach to Assess Quality Control Sample Sizes of Cement-Based Solidification/Stabilization
This paper presents an analytical approach to selecting the sample size required to achieve acceptable quality control in a cement-based solidification/stabilization construction cell program intended for the treatment/containment ... -
Experimental and Analytical Behavior of Short Concrete Columns Reinforced with GFRP Bars under Eccentric Loading
This paper presents experimental and analytical studies on short concrete columns reinforced with glass fiber-reinforced polymer (GFRP) towards characterizing compressive behavior GFRP bars. The experimental program consisted ... -
Numerical Investigation of Fillet Welds in HSS-to-Rigid End-Plate Connections
This paper presents a finite element (FE) investigation on the behavior of fillet-welded hollow structural section (HSS) rigid end-plate connections, wherein the entire weld length is effective. The FE models are validated ... -
Investigation of weld effective length rules for CHS X-connections
A laboratory-based test program was conducted to assess the performance of fillet welds in X-connections between circular hollow sections (CHS). Six full-scale, fillet-welded CHS-to-CHS X-connections were designed to be ... -
Fillet weld effective lengths in CHS X-connections. I: Experimentation
For the first time, an experimental test program was conducted to assess the strength of fillet welds in circular hollow section (CHS) connections. Six large-scale, fillet-welded CHS-to-CHS X-connections were designed with ... -
Spatiotemporal assessment (quarter century) of pulp mill metal(loid) contaminated sediment to inform remediation decisions
A bleached kraft pulp mill in Nova Scotia has discharged effluent wastewater into Boat Harbour, a former tidal estuary within Pictou Landing First Nation since 1967. Fifty years of effluent discharge into Boat Harbour has ... -
Compressive Behaviour of Concrete Cylinders Reinforced with Glass Fiber Reinforced Polymer Bars
Current design standards ignore any contribution of glass fiber reinforced polymer (GFRP) bars in concrete in a state of compression. This paper challenged this convention by testing 30 cylinders of 36 MPa concrete to ... -
Short Concrete Columns Reinforced with GFRP Rebars under Eccentric Loading
In this paper, the compressive performance of short concrete columns reinforced with glass fiber-reinforced polymer (GFRP) composite rebars is evaluated. A total of fourteen 500 mm long concrete specimens with square ... -
Structural Behaviour of Sandwich Panels Constructed of Foam Cores and Flax FRP Facings
In this study, the flexural behaviour of sandwich panels constructed of flax fibre-reinforced polymer (FRP) facings and closed cell polyisocyanurate foam cores was examined. A total of nine sandwich beam specimens (1200 ... -
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 ... -
Tensile Properties of Flax FRP Composites
In this study, the effects of the polymer matrix properties and shape of test specimens on mechanical properties of flax fiber-reinforced polymer (FRP) composites are examined. A total of 30 flax FRP coupons were fabricated ... -
Strengthening Concrete Columns using NSM CFRP Laminates
In this paper, the performance of concrete columns strengthened with longitudinal near surface mounted (NSM) carbon fiber-reinforced polymer (CFRP) composite laminates is evaluated. A total of fourteen medium-scale plain ...
