I need information that I'm going to have to present to a County Commision
I posted this once before, but did not obtain any replies from people that know concrete. I am going to try again as my obtaining information on this is a very important matter.
Hillsborough County Florida (that contains the city of Tampa) built a reservoir on the same ground that the Federal Government had already determined through radiation echoing that the ground underneath was too unstable for them to build a 2-story prison on. I know that that is hard to believe, but for we unfortunate tax payers that live her this is an every project event. We live with common things like the construction of the elevated LeeRoy Selman Expressway (He played for the Buccaneers that not only play football in Tampa they support and many even have their own charitable organizations) that every contractor that bid on, except the one that was chosen to actually build it, stated that the ground was to unstable for a single piling system to be used to hold the elevated road. During construction 2 of the pilings basically dropped into the ground naturally taking the roadway with them. This road is now loaded with commuters, so when the next one drops there will be cars on the road.
The contract to build this reservoir called for the contractor to put a 12 inch thick layer of a mixture of concrete and dirt into the walls of this reservoir, that has since been found to be in places only 3 inches thick.
County workers would be caught by a news helicopter pumping concrete into cracks that were forming in the walls of the reservoir when it contained water that had the same weight of just slightly more than 19 Sears Towers on the same ground that the Federal Government determined was to unstable to hold the weight of a 2-story prison.
Go ahead and laugh, it's not your tax money.
Yes, they were pumping concrete into cracks that had formed in the dirt sides of the reservoir. If that immediately made you think “All that is going to do is make the crack move and that without any re-bar the concrete they were pumping into the cracks would eventually just break up, join the club!”
Hillsborough County that is laying off employees and cutting back on services, is planning on throwing $125 million at some type of fix, that still does not take into account that the Federal Government had determined that the ground underneath the reservoir is unstable and might as well just flush that $125 million down the nearest toilet.
HAS ANYONE EVER HEARD OF MIXING CONCRETE AND DIRT TOGETHER? THIS IS SUPPOSED TO BE GIVING SOME LEVEL OF SUPPORT TO THE DIRT WALLS OF THIS RESEVOIR (AT 12 INCHES THICK OR THE 3 INCHES THAT THE CONTRACTOR ACTUALLY PUT IN). NOT SURPRISINGLY, I'VE HUNTED THE INTERNET TO DEATH AND HAVE BEEN COMPLETELY UNABLE TO FIND A SINGLE REFRENCE TO MIXING CONCRETE AND DIRT.
COMON SENSE WOULOD SAY THAT ALL THE DIRT WOULD DO IS WEAKEN THE CONCRETE. UNFORTUNALY FOR ME TO GO IN FRONT OF THE COUNTY COMMISIONERS AND NEWS CREWS THAT FOLLOW THE MEETINGS, I NEED TO HAVE CONCRETE (PUN INTENDED) TO PRESENT TO THEM.
IF YOU KNOW, OR CAN THINK OF ANY SOURCE OF INFORMATION THAT I CAN ACCESS ON WHAT MIXING CONCRETE AND DIRT WILL GIVE YOU PLEASE LET ME KNOW.
That is site is so good that I've seen some questions answered by architects (who might know a source) has me counting on you guys for this one.
