  • 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...

  • A new method of making particleboard with a formaldehyde-free soy-based adhesive

    Creator:
    Prasittisopin, Lapyote
    Abstract:
    Particleboard is widely used for making bookshelf, furniture, cabinets and many other interior products. At present, particleboard is mainly produced with wood particles and urea-formaldehyde (UF) resins. The emission of carcinogenic formaldehyde in the production and use of particleboard has generated an urgent need for development of a formaldehyde-free wood...

  • Seismic performance of reinforced concrete bridge columns constructed with grade 80 reinforcement

    Creator:
    Link, Tim B.
    Abstract:
    The research presented in this thesis assessed the use of high strength steel (HSS) reinforcement for use in reinforced concrete (RC) bridge columns. HSS is not currently allowed in reinforced concrete bridge columns due to a lack of information on the material characteristics and performance information when used in RC...

  • Influence of transport parameters on the fresh and hardened characteristics of ready-mixed concrete

    Creator:
    Chen, Jiaming
    Abstract:
    Most specifications for ready-mix concrete (RMC) limit mixing time to 90 minutes and/or truck drum revolution counts (DRC) to 300 before discharge. These specifications have been in place for many years with the objective of ensuring the quality and performance of the finished concrete product. However, limited research has been...

  • 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...
