  • Influence of High Volumes of Silica Fume on the Rheological Behavior of Oil Well Cement Pastes

    Abstract: Specialized classes of concrete, such as ultra-high-performance concrete, use volumes of silica fume in concrete that are higher than those in conventional concrete, resulting in increased water demand and mixing difficulty. This study considered the effects of eight different silica fumes in three dosages (10%, 20%, 30%) with three w/b (0.20, 0.30, 0.45) on rheological behavior as characterized by the Herschel-Bulkley model. Results indicated that the specific source of silica fume used, in addition to dosage and w/b, had a significant effect on the rheological behavior. As such, all silica fumes cannot be treated as equivalent or be directly substituted one for another without modification of the mixture proportion. The rheology of cement pastes is significantly affected by the physical properties of silica fume more so than any chemical effects.

  • 2017 Hurricane Season: Recommendations for a Resilient Path Forward for the Marine Transportation System

    Abstract: In October 2017, the Coordinating Board of the US Committee on the Marine Transportation System (MTS) tasked the MTS Resilience Integrated Action Team (RIAT) to identify the impacts, best practices, and lessons learned by federal agencies during the 2017 hurricane season. The RIAT studied the resiliency of the MTS by targeting its ability to prepare, respond, recover, and adapt to and from disruptions by turning to the collective knowledge of its members. Utilizing interagency data calls and a targeted workshop, the RIAT gauged the disruptive effect of the 2017 hurricane season and how Hurricanes Harvey, Irma, and Maria affected the operating status of at least 45 US ports across three major regions. This report identifies recommendations to better understand how the MTS can prepare for future storms and identifies activities by federal agencies that are contributing towards resilience. Such actions include hosting early pre-storm preparedness meetings, prioritizing communication between agencies and information distribution, and maintaining or updating existing response plans. Recommendations also target challenges experienced such as telecommunication and prioritization assistance to ports and critical infrastructure. Finally, the report offers opportunities to minimize the impacts experienced from storms and other disruptions to enhance the resilience of the MTS and supporting infrastructure.
