  • A Comprehensive Mechanistic Study on Using Fine Lightweight Aggregate to Mitigate Alkali-silica Reaction

    Creator:
    Li, Chang
    Abstract:
    Previous research has shown that using fine lightweight aggregate (FLWA) can be a promising strategy to mitigate alkali-silica reaction (ASR) in mortar and concrete. While several possible theories were proposed by researchers, discrepancies in testing methods, materials, and supporting evidence still exist. Therefore, this study was initiated. There are two...

  • The use of blended synthetic fibers to reduce cracking risk in high performance concrete (HPC)

    Creator:
    Bañuelos, José
    Abstract:
    High Performance Concrete (HPC) is used in our crucial pieces of infrastructure, such as bridge decks, due to its enhanced durability and engineering properties. However, HPC is highly susceptible to early-age cracking. Cracking within the first months of a bridge deck’s lifespan can severely hinder its long-term performance and durability....

  • Shrinkage study of high performance concrete for bridge decks

    Creator:
    Fu, Tengfei
    Abstract:
    In the field of civil infrastructure, bridge desks are typically constructed using high performance concrete (HPC). Concrete bridge decks demand qualities such as low permeability, high abrasion resistance, superior durability, and long design life. Over decades of field and laboratory experience, many HPC bridge decks have been found to be...

  • Sustainable Design Programs in the United States and Chile

    Creator:
    D'Acci, Hana
    Abstract:
    The purpose of this thesis is to examine and compare sustainable design methods used in the United States and Chile, focusing on sustainable materials and certification programs, to see if sustainable design methods used in the United States can be implemented in Chile to further its sustainable development. Through literature...

  • The role of alumina in the mitigation of alkali-silica reaction

    Creator:
    Warner, Skyler J.
    Abstract:
    The use of fly ash as a supplementary cementitious material (SCM) has increased in the last century due to its various environmental benefits as a recycled product. Within the last 60 years, it has been found that it can be used to effectively control damage induced by Alkali-Silica Reaction. However,...

  • Use of fly ash in the mitigation of alkali-silica reaction in concrete

    Creator:
    Schwing, Kelsea
    Abstract:
    Alkali-silica reaction (ASR) is one of the leading causes of concrete deterioration throughout the world, and affects both structural and non-structural elements. Despite strong research efforts since its discovery by Stanton in the late 1930s, this deteriorating reaction is still not clearly understood nor are proper preventative measures effectively applied...

  • 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...

  • 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...

  • 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...

  • 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...
