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 ... -
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 ... -
Improved Design-Oriented Confinement Models for FRP-Wrapped Concrete Cylinders based on Statistical Analyses
This paper introduces improved design-oriented confinement models for cylindrical concrete members wrapped with fiber reinforced polymer (FRP) composites based on a rigorous statistical evaluation of a large database. As ... -
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 ... -
Bond-Slip Analytical Formulation toward Optimal Embedment of Concrete-Filled Circular FRP Tubes into Concrete Footings
This paper presents a robust analytical model for a moment connection of concrete-filled fiber reinforced-polymer (FRP) tubes (CFFTs) to concrete footings. The CFFT connection is based on a simple approach of direct embedment ... -
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 ... -
Experimental Study of Rectangular RC Columns Strengthened with CFRP Composites under Eccentric Loading
This paper presents the results of experimental studies on reinforced concrete columns strengthened with CFRP composites under combination of axial load and bending moment. A total of seven large-scale specimens with ... -
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 ... -
Flexural Behavior of Sandwich Panels made of FRP Composites: Synthetic and Natural Fibers
Sandwich panels made of fiber-reinforced polymer (FRP) skins and light-weight core materials have the potential to be effectively used in several structural applications such as cladding, decking, and roofing panels. The ... -
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 ... -
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 ... -
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 ... -
Manufactured aggregate from cement kiln dust
This paper presents the results of a laboratory study that evaluated the geotechnical and geoenvironmental properties of a manufactured aggregate derived from cement kiln dust (CKD). The aggregate manufacturing process ... -
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 ... -
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 ... -
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 ... -
Numerical Analysis of Longwall Mining Layout for a Wyoming Trona Mine
At Solvay Mine, located in southwestern Wyoming, a subhorizontal trona seam is mined at depths of between 460-490 m using mechanized room-and-pillar and longwall mining methods. The stratigraphy at the mine generally ... -
ASSESSMENT OF TWO THERMALLY TREATED DRILL MUD WASTES FOR LANDFILL CONTAINMENT APPLICATIONS
Offshore oil and gas drilling operations generate significant amounts of drill mud waste, some of which is transported onshore for subsequent thermal treatment (i.e. via thermal remediation). This treatment process results ... -
Statistical Sample Size for Quality Control Programs of Cement-Based Solidification/Stabilization
Sampling requirements for the quality control (QC) of cement-based solidification/stabilization (S/S) construction cells do not currently specify the sample size considering the accuracy of the estimated effective hydraulic ... -
