Development Length of 0.6 in. Prestressing Strands in Precast, Prestressed Calcium Sulfoaluminate Cement Concrete
(2016-12-16)
Calcium sulfoaluminate cement is a very rapid setting, hydraulic cement that releases
approximately half as much carbon dioxide during production as conventional portland
cement. Calcium sulfoaluminate cement produces ...
QUANTIFYING HYDRAULIC CONDUCTIVITY IN MINE DRAINAGE PASSIVE TREATMENT SYSTEM VERTICAL FLOW BIOREACTORS
(2016-12)
Heavy industrial mining has occurred in the United States for more than 100 years, and in many cases, has led to large-scale environmental degradation, especially from historical operations where mining occurred prior to ...
EVALUATION OF STORMWATER TREATMENT BY VARIOUS REACTIVE MEDIA FOR BIORETENTION CELL DESIGN CONSIDERATIONS
(2018-05)
Bioretention cells (BRC) can be effective at filtering particulate pollutants from stormwater runoff, but substantial removal of the dissolved pollutant fraction is challenging. Various reactive treatment media for BRCs ...
Validation of Portable Handheld X-Ray Fluorescence (PHXRF) on Stabilized Subgrade Projects for Construction Quality Control and Geotechnical Forensic Investigations
(2016-05-13)
Problematic subgrade soils are often strengthened through pozzolanic reactions and/or cementing using various types of chemical stabilizers, such as lime, cement kiln dust, and fly ash. The amount of stabilizer needed for ...
PERFORMANCE MONITORING AND ANALYSIS OF GEOSYNTHETIC REINFORCED SOIL INTEGRATED BRIDGE SYSTEMS (GRS-IBS) IN OKLAHOMA
(2017-05-12)
In 2013, the University of Oklahoma, together with the Oklahoma Department of Transportation (ODOT) and the Oklahoma Bureau of Indian Affairs (BIA), started a feasibility study of GRS-IBS, which had been promoted by the ...
Ultra-High Performance Concrete for Connections of Precast, Prestressed Girders Made Continuous for Live Load
(2019-08-01)
Continuity joints have often been employed in bridges with precast, prestressed girders to increase the overall ability of bridges to distribute live loads by making two simple spans continuous. However, if the continuity ...
Evaluation of Surface Preparation and Bond Angle Combinations for Joint Replacement using Ultra-High Performance Concrete
(2018-05-12)
Deterioration of bridges is often attributed to declining performance of the longitudinal connections between precast members or transverse deck joints. Ultra-high performance concrete (UHPC) is a cementitious composite ...
INFLUENCE OF RETARDERS ON SHRINKAGE AND COMPRESSIVE STRENGTH IN RAPID SET CONCRETE
(2018-05-12)
The purpose of this project is to study the influence and behavior of citric acid on calcium sulfoaluminate (CSA) concrete and compare with industry standard retarders. A review of the available literature on calcium ...
Comparative Hydraulic and Cost Analyses of Single and Dual Water Distribution Systems Using Nonpotable Water for Urban Irrigation in Norman, Oklahoma
(2017-12)
Drought has caused water resource shortages throughout Western and Midwestern United States for many years, particularly in California, Nevada, Arizona, Texas, and Oklahoma. This has led many communities to evaluate alternate ...
TOTAL WATER LEVEL MODELING IN THE NORTH CAROLINA COASTAL PLAIN: COMPARING ADCIRC AND HEC-RAS
(2017-12-15)
The purpose of this Master’s thesis was to develop and compare an ADCIRC and ADCIRC/HEC-RAS paired model for the purpose of total water level forecasting using the Tar River and Pamlico Sound area as a test case. ADCIRC ...
