  1. Mafia Not Happy !! Dr. “Vito Corleone" Cosentino Makes Concrete Float

  2. Floating Concrete? Is Someone Swimming with Da Fishes?? Sir your Concrete Canoe Floats Full of Water??

  3. No Way How Can Italians DO Such A Thing? I know!! No one ever believes these float full of water!!

  4. 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

  5. Paddling and Presenting

  6. 2011 Ninth in North America!

  7. Paddling is more fun Notice the other boats?

  8. 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

  9. 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 • http://www.nextag.com/concrete-shoes/search-html

  10. 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!!”

  11. 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 oF 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!!

  12. The Bottom Line is we have fun

  13. Testing Concrete • Compression • Tension • Bending

  14. Construction Specifications • Ultimate Compressive Strength • Units • Force divided by area • Pounds per square inch • psi • Kilonewtons per square meter • kN/m2 or kilopascals kPaWhat area is used?

  15. Typical Concrete Strengths • Sidewalk = 3000 psi =21,000 kPa • Interstate Highway = 5000 psi = 35,000 kPa • High-rise Buildings = 10,000 psi = 70,000 kPa

  16. 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 • Today’s Ready Mix Trucks Carry 10 cubic yards

  17. Corleone’s Research Overview • Optical Fiber Sensors for Civil Structures • Traffic Classification and Weigh in Motion • Chloride Detection in Concrete • Reuse of Waste Materials in Highway • Waste to Energy Ash • Waste Tire • Waste Glass • Recycled Concrete Aggregates • Reclaimed Asphalt Pavement (you can call me P-diddy) • The Mysterious Case of the Bouncing Piles

  18. Optical Fiber Sensors • Low Cost • Lightning Resistant • Placed in a pavement groove • Determine if Motorcycles, Cars, Buses Trucks • Federal Highway Administration has 13 classes

  19. Typical Fiber-optic Traffic Classification System

  20. 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

  21. The Mysterious Case of the Bouncing Piles SR 20 Bridge over Rocky Bayou WB Bent 24; Pile 1 1999 3 1/16th inch Max. Displacement 2 7/8thinch Rebound • 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….. 3/16th inch Set

  22. Anderson Street PDA vs. Elevation High Rebound to Elev. 55 NAVD Elevation (ft) High Rebound at Elev. 28 2330 Blows w/ Bouncing Maximum Displacement &Rebound (in)
