  1. The Development of Sustainable Internal Curing Agents Using Natural Hollow Fibres

    Sabziparvar, AmirmohammadUniversité d'Ottawa / University of Ottawa2024

    The incorporation of superabsorbent materials as internal curing agents has demonstrated effectiveness in mitigating self-desiccation and early-age cracking in cement mixes characterized by low water-to-binder ratios (w/b). However, concerns related to sustainability, availability, and cost have …

  2. Drinking Water Treatment Waste as an Alternative for Internal Curing and Cement Replacement in Concrete

    Nowasell, Qiwei CaoUniversity of Missouri--Kansas City2016

    … shrinkage can be controlled by appropriate curing methods, however proper curing does little to affect autogenous shrinkage, especially in low water-to-cementitious ratio (w/cm) systems. Internally supplying additional water, not part of the original mixing water, on an as-needed basis to …

  3. Investigating repair mortars containing superabsorbent polymers as a method of internal curing to improve concrete patch repair performance

    Gillmer, MarcDepartment of Civil Engineering2012

    Concrete structures are designed with a specific service life in mind and deteriorate over time due to their exposure to environmental conditions. In order to increase the service life of concrete structures, they can sometimes be rehabilitated and repaired using concrete overlays. However, …

  12. Mitigation of early age cracking of concrete for bridge decks

    Wilson, William OliverUniversity of Illinois at Urbana-Champaign2013

    In order to reduce reconstruction time and costs in order to better serve the general public a need has arisen for longer service life when considering concrete bridge decks for highway applications. Service life of concrete bridge decks is often cut short indirectly, due to deterioration …
