Equilibrium and Non-equilibrium Thermodynamic Modeling of Cement Pastes Containing Supplementary Cementitious Materials

Creator:: Glosser, Deborah B.
Abstract:: Thermodynamic modeling of cementitious material is an established tool for predicting the hydrated phase assemblages, pore solution pH, and pore solution composition of mixtures of various chemical compositions and water-to-binder (w/b) ratios. However, traditional thermodynamic techniques have major limitations for modeling mixtures containing supplementary cementitious materials (SCM), and when modeling...

Quasicrystal Formation, Structure and Indentation Behaviors in Pure Tantalum

Creator:: Wang, Zhengming
Abstract:: Spontaneous quasicrystal (QC) formation has not been observed in pure metals either in computation or in experiments (excluding epitaxial growth of thin atomic layers on a QC template). In this thesis work, dodecagonal QC (DDQC) grains are first discovered to spontaneously form during thermal devitrification of pure tantalum (Ta) metallic...

Development of Practical Accelerated Testing Protocols for the Performance Evaluation of Concrete against Microbially Induced Corrosion of Concrete

Creator:: Erbektas, Ali Riza
Abstract:: Sustainable wastewater infrastructure systems are vital for civilizations to protect public health. Most of the structural elements of wastewater infrastructure are constructed using concrete owing to its versatility, low cost, and durability. Concrete structures that are exposed to wastewater can experience Microbially Induced Corrosion of Concrete (MICC), which is a...

Assessing durability of reinforced concrete and ductile iron

Creator:: Shields, Silas A.
Abstract:: The first goal of this master’s thesis was to investigate the linkage between a non-destructive testing method, surface resistivity, and premature concrete deterioration brought on by chloride ingress and or freeze-thaw cycling. The experimental method for this project consists of taking surface resistivity measurements of reinforced concrete slabs after they...

Significance of High-Pressure-Torsion Processing on an Aluminum-Lithium Aerospace Alloy

Creator:: Keller, Marina
Abstract:: Aluminum alloys are popular in aerospace and automotive industries because of their relatively high strength-to-weight ratio. The study of enhancing aluminum’s mechanical properties through grain refinement is especially important. One such technique is High-Pressure Torsion processing (HPT), which leads to significant grain size refinement and enhances mechanical properties like ductility...

Delay Performance Evaluation of the IEC 61850 Standard in Power Transmission Substations

Creator:: Safdar, Salman
Abstract:: Substations are a crucial element at the transmission and distribution level of electric power systems. The primary substation equipment (power transformers and high voltage switching equipment) is used to transfer and transform electric energy by stepping up or down the voltage in transmission substations. Secondary equipment (such as IEDs, Intelligent...

Application of Spectroscopic Techniques for In-Situ Oxygen Monitoring in Liquid Sodium

Creator:: Walton, Seth L.
Abstract:: In liquid sodium environments like those proposed for next-generation sodium fast reactors (SFRs), the presence of impurities in the sodium, particularly chemical species containing oxygen, can lead to increased corrosion on sodium-wetted components. It is important to monitor oxygen concentration in the sodium melt, but temperatures of 500 ℃ and...

Design, Fabrication, and Evaluation of a Novel High-Performance Resistance Heater Rod for Nuclear Thermal Hydraulic Experimentation

Creator:: Sharaf, Salem A.
Abstract:: The Accident Tolerant Fuels campaign demonstrated a need for nuclear fuel pin simulators to further research fuel and cladding combinations that can withstand off normal conditions in light water reactors. The use of a heater rod as a fuel pin simulator greatly reduces the risk involved during testing as no...

A Numerical Investigation of the Bearing Capacity of Shallow Foundations on Salt-Encrusted Flat Sabkha

Creator:: Refaei, Raied
Abstract:: Salt-encrusted flats, or Sabkha, are common in arid and semi-arid regions worldwide, including coastal and inland areas. Due to their low shear strength and high compressibility, these soils are often unsuitable for supporting infrastructure or structures. The unique salt content of sabkha formations sets them apart from other soil types....

On the Role of Particle Size Distribution in Selective Laser Melting of 316L Stainless Steel

Creator:: Coe, Hannah G.
Abstract:: Selective laser melting (SLM) is an additive manufacturing (AM) process that uses a laser beam to melt metal powder as it is spread onto the build surface using a roller or scraper, followed by rapid solidification to manufacture a 3D component, one layer at a time. In SLM process, density...
