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...

Chemical transformation of rice husk ash for sustainable, constructable, and durable binary cementitious system

Creator:: Prasittisopin, Lapyote
Abstract:: The production of cement and concrete results in the production of large amounts of CO₂ emissions which can have significant negative environmental impacts. Using supplementary cementing materials (SCMs) as a cement replacement is an effective solution to reduce these negative environmental impacts, as most SCMs are waste by-products from other...

Non-destructive determination of yield stress for in-situ gusset plates

Creator:: Pflaum, Therese Michelle
Abstract:: Failure of a gusset plate that caused the I-35W Bridge collapse in Minneapolis, MN resulted in mandated rating of connections by the Federal Highway Administration (FHWA). Rating connections requires material properties as an input. The material properties are generally reported on the available detailed drawings for bridges. However, some bridges...

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...

The Processing and Microstructures of 309L Stainless Steel Clad onto Carbon Steel with Wire-fed Directed Energy Deposition

Creator:: Bozeman, Scott C.
Abstract:: Directed energy deposition and laser cladding technologies are suitable advanced manufacturing techniques for applying corrosion-resistant claddings to large carbon steel components. In this work, we clad 309L stainless steel wire onto carbon steel substrates and examine the effects of cladding parameters (laser power and travel speed) on metallurgical bonding, composition,...

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...

Synthetic Lubricant Performance in Enclosed Gearbox Applications at Extreme Temperature

Creator:: Marr, Carter J.
Abstract:: The goal of this paper is to evaluate how synthetic lubricants perform in an enclosed gearbox application when compared with a proven mineral oil. This is in an effort to improve gearbox efficiency with the desired effect of lower emissions from of improved energy output from power generation. Four liquid...

The Evaluation of Cementitious Pore Solution Composition and Electrical Resistivity Using X-ray Fluorescence (XRF)

Creator:: Tsui Chang, Marisol
Abstract:: Interest in performance specifications has been growing in the civil and construction industry in the past decade. One major focus area has been on understanding how to prolong the service life of concrete structures, since repair and rehabilitation of existing infrastructure have cost many trillions of dollars. Deterioration mechanisms such...

Density Functional Theory Study of the Reaction Mechanism of Chloride-induced Depassivation of α-Fe2O3

Creator:: Pang, Qin
Abstract:: Carbon steel, which contains mostly iron, has been widely used as reinforcement in reinforced concrete. In the alkaline environment in reinforced concrete, a thin iron oxide film, called the passive film, forms on the surface of the steel, which protects the surface from active corrosion. The exact atomic structure of...

Factors Influencing Conversion and Volume Stability in Calcium Aluminate Cement Systems

Creator:: Adams, Matthew P. (Matthew Peter)
Abstract:: There is renewed interest in North America for the use of calcium aluminate cement (CAC) in infrastructure repair. The interest is driven by the specialty properties that make CAC the ideal candidate for particular applications. These include rapid strength gain, even at temperatures approaching 0°C, the ability to customize fresh...
