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

National Concrete Canoe
Champions during 22 year history

U C Berkeley

Michigan State

Alabama Huntsville

South Dakota School of Mines

Clemson University

Wisconsin

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 your 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
