Mitigation of early age cracking of concrete for bridge decks
… due to deterioration mechanisms that exist at early ages of the concrete. Early age deterioration mechanisms such as early age cracking cause the reinforcing steel rebar to be exposed prematurely to the elements of the environment, which causes for lower service life of the bridge deck through …

Prediction of early-age cracking of UHPC materials and structures : a thremo-chemo-mechanics approach
… ductility, economical benefit, etc., but early-age cracking of UHPC can become an issue during the manufacturing process due to the high cement content and the highly exothermic hydration reaction. Because of the risk of early-age UHPC cracking, there is a need to develop a material model …

Study of Internal Strains Developed in Concrete Decks at Early Ages in Steel Continuous Bridges
… (ARDOT) has identified bridge deck cracking shortly after concrete decks are placed and prior to applying traffic loads. Previous researchers have confirmed improper construction practices and design methods can lead to deck cracking. Currently, many contractors throughout Arkansas …

Numerically Modeling Steel Continuous Bridges for Early Age Concrete Deck Cracking
<p>Early age bridge deck cracking is a common problem throughout the United States. Early age cracking develops shortly after the deck is poured. It reduces the serviceability and lifespan of bridges. Early age cracking can be typically attributed to either of two factors, 1) construction …

Development of low-clinker concrete: partial replacement of cement with calcined clay and limestone, based on selected African raw materials
… resistivity, carbonation resistance, shrinkage, and potential for early age cracking. Overall, it can be concluded that the selected LC3 concrete mixes perform similarly or better than the reference mixes. The results indicate that, apart from kaolinite content, factors that influence the …

The Development of Sustainable Internal Curing Agents Using Natural Hollow Fibres
… 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 emerged, …

Noncontact sensing systems and autonomous decision-making for early-age concrete
Early-age cracking and spalling in concrete pavements reduces slab capacity, joint load transfer, ride quality, and its long-term performance. These premature distresses lead to increased maintenance costs for sealing, patching, and grinding. Proper timing of sawcutting and curing are two …
