1PM - Bioinspired Cellular Concrete-UHPC Composite Materials This study
1:50PM is to combine two unique materials, namely ultra-high performance
concrete (UHPC, which has a very dense particle packing for high
strength and incorporates a high dosage of microfibers to ensure high
toughness) and cellular concrete (CC, which is a low-density material
produced by incorporating air bubbles in the cement paste matrix), into
a composite material through the fundamental understanding of the
hierarchical structure of bone and active control of the cement-based
materials. By mimicking the microstructure and mechanical properties
Wednesday of bones, the strength-to-weight ratio of the material is believed to be
significantly higher with the combination of the unique features of CC
October and UHPC. Results from the study demonstrated that it is feasible to
create this UHPC-CC composite material that is similar to the compact-
20 cancellous bone structure with lightweight yet excellent (static and
dynamic) mechanical behavior. The lightweight precast structure
elements could minimize the efforts and costs during transportation. I In
addition, this composite material with strong shells or skins and energy
absorbent core could be implemented for applications such as impact
or explosion protective barriers, as they are prone to transform the
kinetic energy during the impact in deformation energy.

1PM - Creating Reusable Roof Insulation Systems with Lightweight Fill The
1:50PM presentation takes an in-depth look at the composition of aggregate
and cellular lightweight insulating concrete systems. The attendees
will be presented with the unique performance and application
characteristics and considerations in high wind uplift, plaza deck, and
metal deck design applications. How to specify and design a reusable
roof and plaza deck insulation system that minimizes environmental
impact, provides enhanced protection in high wind uplift locations,
and provides fire and thermal resistance in order to protect the
occupants & ensure business continuity. Identify how aggregate and
cellular lightweight insulating concrete systems derive their lightweight
properties.Learn about aggregate sourcing and how it can potentially
contribute to achieving LEED goals. Learn about benefits and limitations
of both aggregate and cellular lightweight insulating concrete systems.
Understand how design application impacts LWIC system selection.

2PM - Light Weight Fill at Port Canaveral’s Cruise Terminal 3 Wharf In
2:50 PM 2020 the Canaveral Port Authority (CPA) completed the rebuild of
Cruise Terminal 3 (CT3) Berth to accommodate the increasing size of
ultra-large cruise vessels. The original CT3, constructed in 1983, was an
open pile standoff wharf with a shallow bulkhead wall. Because cruise
ships have more than doubled in length since 1983, and because the
wharf’s deck was not designed for the heavy wheel loads from mobile
passenger gangways, the open pile wharf was deemed functionally
obsolete. In 2017 the Jacobs design team started the planning, design,
and permitting of the replacement berth that will use a deep bulkhead
wall positioned seaward of the existing shallow wall. Lightweight fill
would be used as part of the backfill between the existing and new
walls. Construction started in July 2018 and was completed in March
2020. And finally, the presentation will show some of the lessons learned
from using LWF in marine construction and how future wharf designs at
Port Canaveral could be modified to mitigate some of the construction
issues.
