The effects of temperature on compressive strength of rapid setting concrete
(2011)
Rapid setting concrete using Calcium Sulfoaluminate (CSA) cement has been around since the 1960's to meet the need for construction projects with limited time frames. These projects range from quick foundation work to rapid ...
The Use of Recycled Material Backfills to Mitigate the Effects of Expansive Soils on Subterranean Structures
(2016)
The extreme annual weather patterns of the Midwest United States have created a demand for basements as emergency shelters in both residential and commercial structures. However, with the majority of the Midwest experiencing ...
INTERNAL CURING OF CALCIUM SULFOALUMINATE CEMENT CONCRETE USING LIGHTWEIGHT AGGREGATE
(2018-05-12)
Calcium sulfoaluminate (CSA) cement is a very rapid setting, hydraulic cement that releases approximately half as much carbon dioxide during production as conventional portland cement. CSA cement produces concrete with ...
Modeling and Evaluation of Constituents of Emerging Concern Through Wastewater Treatment Processes
(2016-05-13)
Constituents of emerging concern (CECs) have accumulated in drinking water source supply over the past decades. Although there are currently no established treatment standards, CECs should be of concern to the public and ...
Evaluating Low Impact Development Best Management Practices as an Alternative to Traditional Urban Stormwater Management
(2016-08-12)
The Trailwoods residential neighborhood (Norman, OK) included two instrumented watersheds (each approximately 2.3 acres), with the purpose of quantifying the impact on stormwater quantity and quality through implementation ...
Seismic Performance of Grouped Helical Piles in Pinned and Fixed Connections
(2018)
Helical piles have yet to be nationally considered an acceptable foundation for structures in areas of high seismic activity. This remains despite evidence of helical pile survival stories from recent earthquakes where ...
ROLLING-TYPE ISOLATION: AN EXPERIMENTAL CHARACTERIZATION AND NUMERICAL PARAMETRIC STUDY
(2017-12-15)
Building contents and nonstructural components are known to be vulnerable during seismic events. Of particular concern is computer and network equipment that is critical in the post-earthquake recovery process. A solution ...
Microcosm assessment of natural processes affecting chemicals of emerging concern in secondary effluent
(2017-05)
The fight for new water sources is over, reclaimed water is next. Currently, the City of Norman supports its water needs via Lake Thunderbird (LT) and the Central Oklahoma Aquifer System (COAS). In times of peak demand, ...
Soil Trace Metals Concentrations in A Mining Impacted Agricultural Watershed: Comparison of Analytical Methods, Geospatial Distribution, and Evaluation of Risk
(2018-05-11)
This study investigated four aspects surrounding lead, zinc, and cadmium soil trace metals concentrations within a mining impacted watershed: (1) a comparison of three soil trace metal quantification methods relating ...
Performance of Fiber-Reinforced Self-Consolidating Concrete for Repair of Bridge Sub-Structures
(2016-05)
The damage of various reinforced concrete elements accounts for significant annual expenditures by state and federal transportation agencies on bridge maintenance, repair, or replacement. With the rising costs of materials ...
