  • 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...

  • Autogenous deformation and chemical shrinkage of high performance cementitious systems

    Creator:
    Fu, Tengfei
    Abstract:
    In the past ten years, renewed research interest has shown the benefits of internal curing by incorporating saturated lightweight fine aggregate (LWFA) in high performance concrete (HPC). As a result, the technology of internal curing has steadily progressed from laboratory studies to field applications. To determine the optimum LWFA content,...

  • 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...

  • 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...

  • Durability and Performance of High Early Strength Concrete for Structural Bridge Deck Overlays

    Creator:
    Smith, Jeremy A.
    Abstract:
    High early strength concrete (HESC) allows for faster construction with less impact on traffic, thus reducing the indirect costs associated with a project. There are multiple methods for achieving early strength, such as alternative cements like calcium sulfoaluminate (CSA) or chemically accelerated portland cements. The standard criteria for an HESC...

  • Alkali-silica reaction in concrete containing recycled concrete aggregates

    Creator:
    Adams, Matthew P.
    Abstract:
    Using recycled concrete aggregate (RCA) as a replacement for natural aggregate in new concrete is a promising way to increase the overall sustainability of new concrete. This has been hindered, however, by a general perception that RCA is a sub-standard material due to the lack of technical guidance, specifically related...

  • 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...

  • Internal curing of high-performance concrete for bridge decks

    Creator:
    Deboodt, Tyler
    Abstract:
    High performance concrete (HPC) provides a long lasting, durable concrete that is typically used in bridge decks due to its low permeability, high abrasion resistance, freeze-thaw resistance and strength. However, this type of concrete is highly susceptible to the deleterious effects of both autogenous and drying shrinkage. Both types of...

  • Structural Response of High-Performance Fiber-Reinforced Cementitious Composites: Evaluation, Simulation, and Sensitivity Analysis

    Creator:
    Khlef, Feras L.
    Abstract:
    The constitutive behavior of high-performance fiber-reinforced cementitious composites (HPFRCCs) under mechanical loading is characterized by significant tensile properties that play an essential role in the structural response of several applications in structural engineering. The significance of tensile properties of HPFRCCs in structural engineering is the focus of three manuscripts presented...

  • Investigation of x-ray computed tomography for Portland cement phase quantification

    Creator:
    Deboodt, Tyler J.
    Abstract:
    Cementitious materials are often characterized through the use of advanced analytical techniques to understand the macro-, micro-, and nano-scale properties, including phase formation during hydration, and subsequent potential deterioration mechanisms which can affect service life. A major limitation with using such analytical techniques to quantify solid phases in cementitious systems...
