Evaluating Impact Resonance Testing as a Tool for Predicting Hydraulic Conductivity and Strength Changes in Cement-Stabilized Soils
(American Society of Civil Engineering, 2015)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 ... -
Statistical Sample Size for Quality Control Programs of Cement-Based Solidification/Stabilization
(NRC Press, 2015)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 ... -
Examining freeze/thaw cycling and its impact on the hydrualic conductivity of cement-treated silty sand
(American Society of Civil Engineering, 2015)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 ... -
Hydraulic and strength performance of three cement-stabilized soils subjected to cycles of freezing and thawing
(NRC Research Press, 2015-03)A total of 108 specimens were prepared to examine the hydraulic performance and strength performance of nine different cement-stabilized soils under unexposed and freeze–thaw exposed conditions. Specimens from each mix ... -
Improved Design-Oriented Confinement Models for FRP-Wrapped Concrete Cylinders based on Statistical Analyses
(Elsevier, 2015-03-15)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 ... -
Strengthening Slender Reinforced Concrete Columns Using High-Modulus Bonded Longitudinal Reinforcement for Buckling Control
(American Society of Civil Engineers, 2015-04)This paper introduces a model for strengthening slender reinforced concrete columns. The proposed technique aims at controlling second-order lateral deflections using longitudinal high-modulus bonded reinforcement, thereby ... -

Manufactured aggregate from cement kiln dust
(Institute of Civil Engineers Publishing, 2016)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 ... -
Numerical Analysis of Longwall Mining Layout for a Wyoming Trona Mine
(Elsevier, 2016)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 ... -
Experimental Evaluation of Design Procedures for Fillet Welds to Hollow Structural Sections
(American Society of Civil Engineers, 2016)This paper discusses contemporary design procedures for fillet welds to Hollow Structural Sections (HSS) in several prominent design codes. The structural reliability associated with the "directional strength enhancement ... -
Experimental and Analytical Behavior of Sandwich Composite Beams: Comparison of Natural and Synthetic Materials
(SAGE, 2016-05-31)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 ... -
Long-Term Tensile Properties of Natural Fibre-Reinforced Polymer Composites: Comparison of Flax and Glass Fibres
(Elsevier, 2016-06)Despite of significant research on the mechanical properties of fibre-reinforced polymer composites made of natural fibres, long-term performance of the natural fibre composites against moisture and other environmental ... -
Flexural Behavior of Sandwich Panels made of FRP Composites: Synthetic and Natural Fibers
(CSCE, 2016-06-01)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 ...
