Internal curing of high-performance concrete for bridge decks

Creator:: Deboodt, Tyler
Abstract:: High performance concrete (HPC) provides a long lasting, durable concrete that is typically used in bridge decks due to its low permeability, high abrasion resistance, freeze-thaw resistance and strength. However, this type of concrete is highly susceptible to the deleterious effects of both autogenous and drying shrinkage. Both types of...

Characterization of reinforced fill soil, soil-reinforcement interaction, and internal stability of very tall MSE walls

Creator:: Walters, James J.
Abstract:: In many geotechnical design situations involving tight right-of-way constraints, Mechanically Stabilized Earth (MSE) walls are often the most cost-effective and reliable earth retention technology among available alternatives. However, few well-documented case histories with detailed material testing, instrumentation programs and construction observation of performance are available in the literature. Despite the...

The effect of boundary geometry on internal density currents in a density stratified reservoir

Creator:: Spurkland, Torbjorn
Abstract:: The effects of boundary geometry on internal density currents in a density stratified reservoir were investigated in a laboratory model. When water was simultaneously withdrawn and admitted to the reservoir, a complex current regime was established. The general flow pattern is described, and the influence of physical variables on the...

Toward a mixture design methodology for internally cured concrete that considers filling specific pore sizes caused by self-desiccation

Creator:: Montanari, Luca
Abstract:: Internal curing is a term used to describe a process in which curing water is provided to a concrete mixture from inside the mixture. Internal curing water has typically been provided in North America mixtures by using prewetted porous materials, like fine lightweight aggregate (FLWA). Alternative materials, such as superabsorbent...

Analysis of moving loads using force-based finite elements

Creator:: Kidarsa, Adrian
Abstract:: An analysis method for moving loads computes the internal demand history in a structural member at integration points of force-based finite elements as opposed to the end forces of a refined displacement-based finite element mesh. The force-based formulation satisfies strong equilibrium of internal section forces with the element end forces...

Entering streamflow effects on currents of a density stratified model reservoir

Creator:: Elwin, Elmer Harvey
Abstract:: The effect of entering streamflow on currents of a density stratified reservoir has been studied in a laboratory model to provide insight into the prediction, control, and maintenance of quality water discharge from a thermally stratified reservoir. Twenty experiments were performed using various concentrations of a sodium chloride solution to...

The development of a gas-permeable-membrane-supported (GPMS) biofilm reactor for the combined anaerobic/aerobic treatment of polychlorinated biphenyls

Creator:: Polonsky, Jon D.
Abstract:: A continuous flow, gas-permeable-membrane-supported (GPMS) biofilm reactor was developed to facilitate the treatment of polychlorinated biphenyls (PCBs). The GPMS biofilm reactor consisted of a cylindrical glass vessel made up of three compartments: the gas, liquid and headspace compartments. A gas-permeable membrane separated the bottom gas compartment from the liquid compartment....

Stability of heterogeneous and anisotropic slopes determined by the compound logarithmic spiral limit equilibrium method

Creator:: Stockton, Ezra J.
Abstract:: The logarithmic-spiral (log-spiral) limit equilibrium procedure for slope stability analysis rigorously satisfies both force and moment equilibrium with a failure surface geometry formulated as a function of the soil’s angle of internal friction. Within the framework of limit equilibrium, this procedure has, in the past, been primarily limited to homogeneous...

Environmental Regulations Reconsidered : Identifying Incentives and Barriers to Environmental Performance

Creator:: Craig, Kathleen D.
Abstract:: Attention has been drawn to the observation that environmental benefits under the current regulatory approaches are diminishing with respect to increased pollution control costs. Regulators have begun to appreciate that while environmental gains can still be achieved under the current command and control system, the most significant environmental gains have...
