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...

Evaluation of the Efficiency of Supplementary Cementitious Materials to Prevent Alkali-Silica Reaction in Concrete with Highly and Very Highly Reactive Aggregates

Creator:: Chopperla, Krishna Siva Teja
Abstract:: The most common test methods to evaluate alkali-silica reaction (ASR), the concrete prism test (CPT) and the accelerated mortar bar tests (AMBT), have limitations and are not entirely reliable in terms of predicting the performance of concrete with prevention measures under field conditions. In this study, the miniature concrete prism...

Influence of Concrete and Construction Parameters on Chloride Test Measurements and Critical Chloride Threshold Limits

Creator:: Vaddey, Naga Pavan
Abstract:: The issue of chloride-induced corrosion of reinforcing steel in concrete and its economic impacts are well-known. Chlorides that cause reinforcement corrosion can be from constituent materials used to prepare concrete or can enter the hardened concrete when the structure is exposed to chloride environments. To minimize the risk of reinforcement...

Assessing Durability of Concrete and Ettringite Accelerated Cementitious System

Creator:: Sarkar, Anika T.
Abstract:: The goal of the first part of this project was to investigate the influence of aggregate source and entrained air on the transport properties of concrete. Currently, there are several ASTM standards available that provide systematic procedures to evaluate mass transport properties of concrete. ASTM C642-13 (ASTM 2013), often referred...

Improving the Performance of High Early Strength Concrete by Controlling Self-Desiccation and Mitigating Shrinkage

Creator:: Wilson, Cameron A.
Abstract:: High early strength (HES) concrete is becoming increasingly used to repair damaged concrete pavement sections. The use of HES concrete enables the repaired pavement to be opened to traffic within hours of placing the concrete. A common approach used for the rapid repair of concrete pavement consists of closing a...

Critical Assessment of Chloride States and Quantities in Ordinary Portland and Specialty Cements

Creator:: Ahmed, Ahmed Abdulhaq
Abstract:: The constituent materials of concrete often contain chlorides. The presence of chlorides in sufficient amounts can disrupt the passive layer, also known as the passive film, that protects the reinforcing steel in concrete. This disruption can lead to premature corrosion of the reinforcing steel in concrete. To minimize the risk...

A Comparison of Formation Factor to Standard Methods to Evaluate Transport Properties

Creator:: Whatley, Samantha N.
Abstract:: Chloride-induced corrosion is one of the primary causes of the degradation of reinforced steel in concrete structures. Currently, the rapid chloride permeability test (RCPT) is the most specified method to determine the concrete’s resistivity to chloride ingress, thus a determining factor in assessing the durability of concrete. While it is...

The Effects of Temperature on Electrical Resistivity Measurements of Concrete

Creator:: Coyle, Alex T.
Abstract:: Measuring resistivity as a method to calculate formation factor is becoming a popular way to evaluate transport properties of concrete. Resistivity measurements are dependent on multiple factors including the resistivity of the pore solution, leaching effects, the degree of saturation of the specimen, the age of the specimen (degree of...

Toward a mixture design methodology for internally cured concrete that considers filling specific pore sizes caused by self-desiccation

Creator:: Montanari, Luca
Abstract:: Internal curing is a term used to describe a process in which curing water is provided to a concrete mixture from inside the mixture. Internal curing water has typically been provided in North America mixtures by using prewetted porous materials, like fine lightweight aggregate (FLWA). Alternative materials, such as superabsorbent...

High Strength Reinforcing Bars : Concrete Shear Friction Interface Behavior

Creator:: Nielson, Drew R.
Abstract:: Use of high-strength steel (HSS) reinforcing bars could provide constructability and economic benefits for the construction of structures, reducing the initial and ultimately the life-cycle cost of bridge and building structural elements. This thesis summarizes work performed in a research project on the use of HSS reinforcing bars for concrete...
