Development of performance based test procedures for asphalt mixtures

Creator:: Kliewer, Julie E.
Abstract:: In 1987, Congress authorized a 5 year $150 million dollar research program called the Strategic Highway Research Program (SHRP). SHRP was divided into four major areas, including the asphalt research program. The asphalt research program was divided into six major research contracts, one such contract, SHRP-003A was called Performance Related...

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...

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...

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....

Methods for strengthening flexural steel details in reinforced concrete bridge girders using a near-surface mounted retrofitting technique

Creator:: Amneus, Deanna
Abstract:: Many older reinforced concrete deck girder (RCDG) bridges contain straight bar terminations of flexural reinforcement. Common bridge design practice of the 1950s did not consider the additional demands on the terminated bars from shear and flexure. Moreover, more stringent code specifications and heavier permit trucks contribute to the insufficient ratings...

Synergistic Effects of Alkali Silica Reaction (ASR) and Fly Ash on the Corrosion Characteristics of Reinforced Concrete Systems

Creator:: Mazarei, Vandad
Abstract:: Alkali silica reaction (ASR) and corrosion of reinforcement are two deterioration mechanisms in reinforced concrete (RC) structures. These deterioration mechanisms can significantly damage a RC structure and reduce its service life. Supplementary cementitious materials (SCMs) are commonly used to improve the durability of RC systems containing reactive aggregate that are...

Development of Authentic Engineering Curriculum through Collaborative Development: Research on Development and Adoption

Creator:: Cross, Matthew J.
Abstract:: Background: Studies indicate that problems utilized in traditional undergraduate engineering education do not adequately prepare students for the workforce. Calls to implement authentic, ill-structured problems into upper level engineering experiences may address this issue but adopting authentic engineering problems without considering barriers to adoption of faculty has not been fully...

Investigating Accelerated Carbonation Methods for Sequestering CO₂ into Lime Treated Soils

Creator:: Moore, Jaxom
Abstract:: Civil engineers frequently use lime to improve the mechanical properties of weak clayey soils. The production of lime is associated with significant CO₂ emissions. Sequestering carbon dioxide into the stabilized soil can effectively reduce the carbon footprint of the lime. In the presence of CO₂, unreacted lime in the stabilized...
