  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 250 Universities Compete in 20 regions • A National Champion is Crowned Each Year

  5. National Concrete Canoe Champions during 22 year history • U C Berkeley • Michigan State • Alabama Huntsville • South Dakota School of Mines • Clemson University • Wisconsin • University of NevadaReno • The Florida Institute of Technology

  6. 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

  7. 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!!”

  8. 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 Seament!!

  9. The Bottom Line is we have fun

  10. 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
