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?
National Concrete Canoe Champions during 25 year historyU C BerkeleyMichigan StateAlabama HuntsvilleSouth Dakota School of MinesClemson UniversityWisconsinUC San Luis ObispoUniv Nevada Reno The Florida Institute of Technology
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
Testing Concrete

Construction Specifications
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…..
