COSENTINO MAKES CONCRETE
FLOAT

Mafia Not Happy !!

Floating Concrete?

Is Someone

Swimming with


Da Fishes??

Sir your

Concrete Canoe

Floats Full of Water??

No Way How Can Italians

DO Such A Thing?

No one


ever believes

these float

full of water!!

I know!!

There is a Student Competition that
Requires This

The American Society of Civil Engineers:

National Concrete Canoe Competition

Over 300 Universities Compete in 20 regions

A National Champion is Crowned Each Year

Paddling and
Presenting


2011 Ninth in North America!


Paddling is more fun

Notice the other boats?


National Concrete Canoe
Champions during 25 year history

U C Berkeley

Michigan State

Alabama Huntsville

South Dakota School of Mines

Clemson University

Wisconsin

UC San Luis Obispo

Univ

Nevada Reno

The Florida Institute of Technology

Enough with the Fluff

Concrete or Cement

Cement is the Glue

Is Type 1 for you??

Or Maybe Types 2 3, 4 or 5?

Concrete contains Rocks (Aggregates of various sizes)

Now Your Talkin’ that’s how we maka da shoes

Mixing For Da Shoes

A One and a Two and a Three

One shovel of Cement

Two a Shovel of da Sand

Three a Shovel of the Gravel

And just the right amount of Water

Would this be a Volume Based Mix or a Weight
Based Mix?

Remember the saying “The whole 9 yards!!”


Mixing for Our Canoes

Cement Plus Other binders

Fly Ash from the coal power plants

Slag from the steel making process

Light Weight Aggregates
Sand Size


Like Making Popcorn!!

Cook Regular Rocks at over 2000
o
F

and they Pop

Livelight

Perlite

used in potting soil

And the right amount of water

Plus special Chemical Admixtures

That make it easier to work with

Slow the chemical reaction and increase strength


And you get CONCRETE not cement or as they say
here in the South “
Sea”ment
!!

The Bottom Line is we have fun

Reuse of Waste Materials

Florida is running low on highway fill

Often transported by Barge from Canada

Contractors desperately want to use any waste
products

Waste to Energy Ash stopped by
DEP

with low volume

Waste Glass not available in large enough volumes

Waste Tires Burned at Incinerator for
WTE

Ash

Recycled Concrete Aggregates used

RAP is creepy and not very strong but there is plenty

The Mysterious Case of the
Bouncing Piles

Florida has unique geology

Phosphate Mining in Hawthorn Layer

800 feet thick in Bartow area

Soil very strong silty sand with “Fat” Clay

Piles over 100,000 pounds bounce in Hawthorn

Contractors Not Happy when nail not going into
wood…..
