Durability of Concrete Beams with Bonded FRP Composites made of Flax and Glass Fibers
(CSCE, 2016-08-24)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 ... -
Geotextile biofiltration of primary treated municipal wastewater under simulated artic summer conditions.
(Elsevier, 2016-12)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 ... -
THE EFFECT OF FREEZE/THAW CYCLES ON THE PERFORMANCE AND MICROSTRUCTURE OF CEMENT-TREATED SOILS
(American Society of Civil Engineering, 2016-12)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 ... -
Fillet weld effective lengths in CHS X-connections. I: Experimentation
(Elsevier, 2017)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 ... -
Numerical Investigation of Fillet Welds in HSS-to-Rigid End-Plate Connections
(American Society of Civil Engineers, 2017)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
(Balkema, 2017)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 ... -
Experimental and Analytical Behavior of Short Concrete Columns Reinforced with GFRP Bars under Eccentric Loading
(Elsevier, 2017)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 ... -
An Analytical Approach to Assess Quality Control Sample Sizes of Cement-Based Solidification/Stabilization
(NRC Research Press, 2017)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 ... -
Spatiotemporal assessment (quarter century) of pulp mill metal(loid) contaminated sediment to inform remediation decisions
(Springer, 2017)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 ... -
Monitoring Changes in Near-Well Hydraulic Conditions as a Means to Assess Aquifer Clogging

Compressive Behaviour of Concrete Cylinders Reinforced with Glass Fiber Reinforced Polymer Bars
(Canadian Society for Civil Engineering:, 2017-05-31)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 ... -
Structural Behaviour of Sandwich Panels Constructed of Foam Cores and Flax FRP Facings
(Canadian Society for Civil Engineering, 2017-05-31)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 ... -
Short Concrete Columns Reinforced with GFRP Rebars under Eccentric Loading
(Canadian Society for Civil Engineering, 2017-05-31)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 ... -
Tensile Properties of Flax FRP Composites
(6th Asia-Pacific Conference on FRP in Structures, 2017-07-19)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 ... -
Durability of Flax FRPs Exposed to Accelerated Environmental Conditions
(CDCC 2017, 2017-07-19)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 ... -
