DR. “VITO CORLEONE" 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 regionsA National Champion is Crowned Each Year

Paddling and Presenting

2011 Ninth in North America!

Paddling is more fun Notice the other boats?

Enough with the Fluff

Concrete or CementCement 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 shoeshttp://www.nextag.com/concrete-shoes/search-html

Mixing For Da Shoes

A One and a Two and a ThreeOne shovel of CementTwo a Shovel of da SandThree a Shovel of the GravelAnd just the right amount of WaterWould this be a Volume Based Mix or a Weight Based Mix?

Remember the saying “The whole 9 yards!!”

Mixing for Our CanoesCement Plus Other binders

Fly Ash from the coal power plantsSlag from the steel making process

Light Weight Aggregates Sand Size Like Making Popcorn!!Cook Regular Rocks at over 2000 oF and they PopLivelightPerlite used in potting soil

And the right amount of waterPlus special Chemical Admixtures

That make it easier to work withSlow 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

Ultimate Compressive StrengthUnits

Force divided by area

Pounds per square inchpsi

Kilonewtons per square meterkN/m2 or kilopascals kPaWhat area is used?

Typical Concrete Strengths

Sidewalk = 3000 psi = 21,000 kPaInterstate Highway = 5000 psi = 35,000 kPaHigh-rise Buildings = 10,000 psi = 70,000 kPa

Notes:Concrete Densities Average 150 pcf = 23.5 kN/m3

Water is 62.4 pcf or 1 Mg/m3

Saltwater is 64.2 pcf or 1.03 Mg/m3

Reuse of Waste Materials

Florida is running low on highway fillOften transported by Barge from CanadaContractors desperately want to use any waste products

Waste to Energy Ash stopped by DEP with low volumeWaste Glass not available in large enough volumesWaste Tires Burned at Incinerator for WTE AshRecycled Concrete Aggregates usedRAP is creepy and not very strong but there is plenty

The Mysterious Case of the Bouncing Piles

Florida has unique geologyPhosphate Mining in Hawthorn Layer

800 feet thick in Bartow area

Soil very strong silty sand with “Fat” ClayPiles over 100,000 pounds bounce in HawthornContractors Not Happy when nail not going into wood…..
