Girl Orders Rebar. Adventure Follows.

Cracks finger wide are not a finishing problem,
It is either a thickness problem, or a base preparation problem, or both.

Not saying re bar will solve the problem in that case but will be better than fiber,

concrete has compression strength, it has nearly 0 tensile strength, steel has a lot of tensile strength, poly fibers have some tensile strength, but when it comes to length they are not very long, jsut an inch or so, it is basically the same as as bailing twine cut in to lengths but not twisted.

then why don't they use mesh alone when beams and floors and decks are poured and suspended?
last time I was bridge work there was a lot of steel in it.

and when I order concrete form our redi mix, if he says 10:00 it is 10:00 plus or minus 10 Min's unless some thing major has happened, And if that does occure a phone call as soon as a problem arises.

A few years ago the wife and I both worked with a crushing company.

She worked one one of the crushers and I drove trucks and operated the track hoe.

Concrete that was 80 years old. The only stuff holding it together was the rebar.

The rebar is what we picked the chunks up by many times as they were way to large to fit in the bucket.

The crushed rock was sold as CA-6 and the rebar was scrapped as number 1 steel.

I know very little about concrete. I am not a finisher and NEVER have done that type of work.

I have seen millions of tons of old concrete. The stuff with the rebar in it. WAS FAR more stable then with out.

Cracks are a finishing problem....means that too much water was added by the finisher, or slab was poured while the temps or wind was too high and they did not keep the concrete at the proper humidity (100%) until cured. Fissures like you are describing is usually a base problem or something really heavy was driven across it.

The fiber we use is almost microscopic......if you have really good eyes you might beable to see it if you slowly wash the concrete down. Its about 1/8th of an inch long and clear like fishing line........diameter is finer than hair.

The bridge work you talk about is probably paid for with federal money and there for must be done to federal standards......The concrete that is used on federal projects is PCCP which is 12,000 plus PSI, more than 4 times the standard. It also has fiber with steel re-enforcment and the rebar is coated with an epoxy to keep the concrete from eating it up; sometimes you can see this because the re-bar is green. We poured about a two mile section of I-75/I-64 interchange here in lexington about 4 years ago......It was re-bar and fiber re-enforced and the concrete was poured three feet thick for that section of highway because of federal standards requiring that that interchange be concrete paved. They tore it all out this year and re-did it because the concrete cracked.......that is a federal job with federal engineers.....

You are lucky to be in an area with so little demand that you get a truck on time......there are five concrete companies operating 15 plus plants here in lexington and it does not matter which one you call, your truck will probably be 2-4 hours late......and if your a C.O.D. you will not get concrete at all on most days.

Seems to me your DH created the problem after YOU did all the work.
You should have tole him to get his skinny behind on the phone and cancel the order cause then you wouldnt have been Poed for the rude clerk behavior and gotton slammed for breaking YOUR word. You could have jsut blammed him.
LOL
