Hydromechanical Characterization of Cement-Bentonite Slurries in the Context of Cutoff Wall Applications
(American Society of Civil Engineers, 2016)In the one-phase construction of cutoff walls, the slurry plays two contradictory roles: it should be fluid while excavating the trench but behave like a solid of low permeability afterward. For hydraulic containment ... -
Effects of DC Stray Current on Concrete Permeability
(American Society of Civil Engineers, 2016)In the present study, the effects of direct current (DC) stray current on concrete structures were studied with the focus on the effect of concrete rather than corrosion of steel bars. Concrete samples were prepared with ... -
Comparative Thermal and Mechanical Performance of Geopolymers derived from Metakaolin and Fly Ash
(American Society of Civil Engineers, 2016)This paper presents comparative thermal and mechanical performance of geopolymers derived from metakaolin (MK), fly ash (FA), and their combinations. Bending and compression tests, thermogravimetric analysis, scanning ... -
Repeated Autogenous Healing in Strain-Hardening Cementitious Composites by Using Superabsorbent Polymers
(American Society of Civil Engineers, 2016)Autogenous healing is an already-present feature in strain-hardening cementitious materials, but it is an inferior mechanism because it can only heal small cracks in the presence of water. A cementitious material with ... -
Assesment of Pozzolanic Performance of Sugarcane Bagasse Ash
(American Society of Civil Engineers, 2016)Sugarcane bagasse ash is obtained as a by-product from cogeneration combustion boilers in sugar industries, and is reported to be a useful supplementary cementitious material in concrete. A clear evaluation of pozzolanic ... -
Model Studies on Geocell-Reinforced Fly Ash Bed Overlying Soft Clay
(American Society of Civil Engineers, 2016)This paper addresses the effectiveness of geocell mattress prepared with waste plastic bottles with fly ash as a filling material overlying soft clay bed through laboratory model tests. The test beds were subjected to ... -
Performance Evaluation of Hot Mix Asphalt Containing Recycled Asphalt Shingles in Washington State
(American Society of Civil Engineers, 2016)Due to the increasing cost of asphalt binder and also due to environmental considerations, recycled asphalt shingles (RAS) are now allowed to be added into hot mix asphalt (HMA). RAS have been incorporated into HMA with ... -
Replacement of Quartz in Cementitious Composites Using PET Particles: A Statistical Analysis of the Physical and Mechanical Properties
(American Society of Civil Engineers, 2016)This work investigates the mechanical behavior of cementitious composites (mortar) when quartz inclusions are totally or partially replaced with polyethylene terephthalate (PET) particles. A full factorial design is performed ... -
Observation of Fatigue of Bituminous Mixtures Using Wave Propagation
(American Society of Civil Engineers, 2016)Fatigue phenomenon is one of the main distresses observed in pavements. It is therefore quite complex to characterize in the laboratory using traditional fatigue tests. This paper presents the results of an experimental ... -
Geometrical and Material Characterization of Quenched and Self-Tempered Steel Reinforcement Bars
(American Society of Civil Engineers, 2016)Quenched and self-tempered (QST) steel reinforcement bars (rebars) are manufactured by Thermex or Tempcore processes. Characterization studies of QST rebars are mostly limited to reveal the hardened outer layer and some ... -
Characterization of ASR in Concrete by Si29 MAS NMR Spectroscopy
(American Society of Civil Engineers, 2016)Si29 MAS NMR spectroscopy was employed for the evaluation of the alkali-silica reaction (ASR) in laboratory and field concrete specimens. A series of NMR data was collected on the individual constituents of cement as well ... -
Residual Properties of TMT Steel Bars after Exposure to Elevated Temperatures
(American Society of Civil Engineers, 2016)Many reinforced concrete (RC) structures use thermomechanically treated (TMT) bars as reinforcement and are designed to withstand fire loads. Though the properties of mild steel at elevated temperatures have been extensively ... -
Durability against Wetting–Drying Cycles of Water Treatment Sludge–Fly Ash Geopolymer and Water Treatment Sludge–Cement and Silty Clay–Cement Systems
(American Society of Civil Engineers, 2016)The viability of using two waste materials, water treatment sludge (WTS) and fly ash (FA), for developing sustainable masonry units has been previously investigated in terms of strength but the important aspect of durability ... -
Indoor and Outdoor Aging Behaviors of a Heat-Reflective Coating for Pavement in the Chongqing Area
(American Society of Civil Engineers, 2016)The indoor and outdoor aging behaviors of a heat-reflective coating were studied regarding the problems derived from aging and reduced cooling effects. A one-year natural exposure test of the coating on a roof and on ... -
Performance of Corroded Reinforced Concrete Columns under the Action of Eccentric Loads
(American Society of Civil Engineers, 2016)This paper presents an experimental investigation on the performance of RC columns with corroded reinforcing steel bars. The corrosion of steel bars was induced by using a combined electrochemical process and wet-dry cycles. ... -
Analytical Prediction of the Young’s Modulus of Concrete with Spheroidal Aggregates

Viscoelastic Characterization of Asphalt Concrete in Diametral Tension-Compression
(American Society of Civil Engineers, 2016)This work focuses on improving the linear viscoelastic characterization of asphalt concrete materials with a standard indirect tension setup. Three main aspects distinguish this investigation from typical efforts. First, ... -
Equal Arc Segment Method for Averaging Data Plots Exemplified for Averaging Stress versus Strain Curves of Pervious Concrete
(American Society of Civil Engineers, 2016)In common engineering practice, data plots, such as the stress versus strain relationship of materials, are averaged among a series of samples using the mean ordinate (MO) method. This method is reliable as long as the ... -
