Cold In-Place Recycling Characterization Framework For Single Or Multiple Component Binder Systems, Ben C. Cox

Theses and Dissertations

Cold in-place recycling (CIR) is a pavement rehabilitation technique which has gained momentum in recent years. This momentum is due partly to its economic and sustainability characteristics, which has led to CIR market expansion. When pavement network deterioration is considered alongside increasing material costs, it is not beyond reason to expect demands on CIR to continue to increase. Historically, single component binder (SCB) systems, those with one stabilization binder (or two if the secondary binder dosage is 1% or less), have dominated the CIR market and could be considered the general state of practice. Common stabilization binders are either bituminous …

Investigation Into Mechanisms And Mitigation Of Alkali-Silica Reaction In Sustainable Portland Cement Concrete Containing Recycled Glass Materials, Kaveh Afshinnia

All Dissertations

A significant portion of recycled glass from municipal waste streams is not found to be suitable for reuse as cullet in the production of new glass containers, and as a result it is disposed in landfills. One of the appropriate ways to reduce the disposal of waste glass in landfills is by using it in portland cement concrete as an aggregate material and/or supplementary cementitious material to replace portion of portland cement. The high silica content of the soda glass (approximately 70%) can potentially behave as a pozzolanic material when finely ground, which may enhance the mechanical and durability properties …

Evidence Of Ancient Maya Agriculture In The Bajos Surrounding Tikal, Guatemala, Adam Calvin Parker

Theses and Dissertations

Current Central American agricultural practices are environmentally and economically unsustainable, yet the ancient Maya who lived in the same region thrived for thousands of years. Archaeologists have attempted to understand the factors enabling the prolonged success and ultimate collapse of the Maya societies. Some have proposed that the karst seasonal wetlands, called bajos, that border many Maya sites in the region were an influential factor in the Maya's ability to flourish. For the past decade, researchers have used carbon isotope analyses to identify areas of ancient maize agriculture at Maya archaeological sites. In this study, we collected soil samples from …

Landform Architecture As Reconnecting Presence For Campus Complex Design, Yi Wang

Masters Theses

This thesis is an investigation into how land evolves into an architectural presence and representation to reconnect physical construction with social realities, human perception, and environmental considerations. As buildings lose their plasticity and their connection with the surroundings both physically and psychologically, they become isolated in the cool and distant realm of vision, lacking authenticity of material and tectonic logic in their construction. Landform architecture, which allows land to be engaged in an architectural representation, penetrates multi-dimensional architectural meaning through the manipulation of space, material, and structure. The built form of landform architecture is fundamentally developed from articulations of the …

The Source Of Saline Groundwater In The Mississippi River Valley Alluvial Aquifer In Southeast Arkansas, Justin Michael Paul

Electronic Theses and Dissertations

In this study, the source of historical chloride anomalies in the Mississippi River Valley alluvial aquifer from southeast Arkansas is investigated using spatial statistical and geochemical techniques. The spatial statistical and geochemical techniques are employed to determine whether the source of the saline groundwater is due to evaporative processes in the soil column, injection of saline fluids from depth, or infiltration from rivers. Spatial statistical analyses show chloride anomalies in the alluvial aquifer are more closely related to tectonic features associated with the injection of saline fluids from depth than evaporative concentration of soil waters that may have recharged groundwater. …

Evaluating Corrosion Resistance Of Reinforcing Steel In A Novel Green Concrete, Andrea Carolina Ramirez

USF Tampa Graduate Theses and Dissertations

Reinforced concrete structures are expected to have a long service life with minimal maintenance. Corrosion of reinforcing steel is a major factor in reducing concrete structure lifespan, as corrosion products occupy a larger volume than that of the consumed steel and generate tensile stresses that crack the concrete cover. Procedures to control corrosion in traditional concrete, which is made with Portland-cement (PC), have been well established. However, in recent years novel concrete materials based on alternatives to normally cured PC have been developed in response to global needs to reduce greenhouse gases emissions. In particular, a promising new cement has …

Anaerobic Membrane Bioreactors To Treat Municipal Wastewater At Ambient Temperatures, Matthew D. Seib

Dissertations (1934 -)

Anaerobic biotechnology is viewed as a sustainable alternative to aerobic biotechnology for municipal wastewater recovery. However, anaerobic processes have not been successful in cold climates. Past examples have not been able to meet low organic effluent concentrations, or have failed due to biomass washout resulting from low temperature operation and short hydraulic residence time. Recently, the anaerobic membrane bioreactor (AnMBR) has been shown to achieve low effluent organic concentrations and maintain stable anaerobic biomass. However, shortcomings have included high energy demands for membrane operation and poor understanding of microbial community structures within AnMBRs. This dissertation describes efforts to improve AnMBRs …
