"It's what's inside that counts."
This year, we demonstrated a strong
understanding of the fundamentals of Civil Engineering with "ITZ
The interfacial transition zone (ITZ) is the region of the cement paste around the aggregate
particles. It is the weakest link in a normal
concrete matrix and interactions there affect macroscopic
properties, such as strength, permeability, and durability.
relied on molecular and
atomic interactions to help strengthen the ITZ (interfacial transition
zone) and improve macroscopic material properties.
landmark of Civil Engineering:
of our innovations reflect this year’s theme: “It’s what’s inside that counts.” As far as our boat is
concerned, we incorporated advanced design concepts, employed reverse
engineering for mix design, and developed novel construction methods
that allowed us to achieve our design goals.
We built a “natural”
looking product having very few flaws and trust that our “no frills”
approach (no inlays, minimal attributes, and clear sealant) was
billed ITZ Civilized as a landmark
of Civil Engineering.
all in the mix:
The ITZ is characterized by the prevalence of
calcium hydroxide and higher porosity. We
developed a lightweight, high-performance
cementitious composite that capitalized on the interfacial bonding that
took place in conjunction with our admixture and free-fiber reinforcement.
The hydrogen bonds that formed between molecules, or within different parts of a single
molecule provided remarkable changes in the surface
bond strength, not only between the aggregate and the matrix, but also
between the fibers and the matrix.
Our approach is in
stark contrast to traditional methods that have been applied to improve
the aggregate/matrix bonding in the ITZ, such as reducing the size
of the aggregates, using basalt and quartzite as aggregates, or
replacing the cement with ultrafine additions of constituents, such as
silica fume and metakaolin. These traditional methods are limited in
scope, since they do not significantly alter the nature of the
interaction between the aggregate and the matrix.
While building ITZ Civilized, we geared our efforts toward the current trends in
industry to go “green” with a focus on sustainability in design and
mix is “as green as it gets,” since 100 percent of the binders
(excluding cement) and all of the aggregates are recyclables.
concrete mix is more sustainable than most, since it relies on fly ash
as a binder and includes cenospheres as the aggregate. Fly ash, a residue generated by the combustion of coal, is the
largest byproduct of coal-fired power plants. Today it is recovered by
electrostatic precipitators or filter bags, as opposed to being released
into the atmosphere.
occur naturally in fly ash and are microscopic spheres of silica and
alumina filled with air or gases. Typically harvested from the surfaces
of ash ponds, they have a ready, high value market for use as fillers in
both construction and other industries, and new applications, such as
ours, are continually being developed.
year, we were provided with a hull design by ASCE. The observation
made in our design report that “looks can be deceiving” is not only pertinent to
our hull but to ourselves. By submitting to a corporate training program
(see details below), we gained valuable insight into our personal makeup and
developed a better appreciation for team dynamics.
During this stint, we realized that people are our most valuable resource... and
consider ourselves fortunate to have worked with John Bentley,
professional training and
development consultant from Power2Transform (P2T),
to help overcome some of the difficulties that we encountered.

The 2008/09 stint went relatively smoothly considering
that the majority of our teams members were new recruits and this memo
sent to the Chapter, immediately following Nationals, by our newly
elected president sums it up pretty well.
