concrete reinforcing

thinking of a silage pit floor 2000 sq feet for 3 to 400 tons of maize...earth bank sides

Best to speak with an expert, and I don't mean your local concrete gang! :) My lad did an extensive module in concrete at Uni and got the specs on various types of mix/reinforcements for me 3 years ago when I was "discussing" the specs of a Grant job with NE. It was agreed steel was not required in this instance cutting my costs dramatically.

Care to pass them on? I'm fed up of ag builders saying "ooh, X spec will be alright", then ending up with crazy paving after 10 years...

I did mech eng at uni, so concrete is a bit of a mystery to me.

Lad did Civil Eng, so it was a bit of a mystery to me too.... still is!

I'd have a word with him, but he's busy saving the population of Eastern England in charge of an Army MTU, testing the good folk of the locale! Sorry...

Pretty sure a ready mix company should give you the proper specs...

you may not need steel reinforcing, our grain store was concreted 4 years ago and is fibre reinforced instead except the middle bay near the door which does have re bar in. fibre saved a good bit of money if I recall

Bears out what I was advised.... Had one area that takes a hell of a lot of hammer from turning, and it was proposed that this should be a tad more depth, and also have steel as well.

Have done some research this eve. Looks like speccing concrete properly isn't too hard, but is quite involved.

I managed to discern that depending on ground underneath, how it's prepared, what reinforcement, how much traffic and how heavy it is, the appropriate amount of
concrete is between 6 and 10 inches.

I got in touch with a mate who is passing it on to the concrete person in his company. Hopefully she'll just confirm that the spec we have is correct. If not, I have to figure out who is right.

Interestingly, the "damage factor" rises with the fourth power of axle weight; that is if you double the axle weight, the damage factor will be 16 times bigger! (Hence why all our old concrete is breaking up, having had a decade of 7t telehandler on it, rather than the 4t of a Ford 4000 + loader that it was originally designed for.)

Fascinating calculation that! As you say, it kinda explains the damage done to farm tracks as tankers and bulkers got ever bigger too...

Hope you get some solid advice....






Sorry about that pun!!

Have you priced up tarmac? We did our chalk silage pit floor with rolled stone then a layer of tarmac. Brilliant job and cheaper than concrete.

using Heras ? not sure if you should but i can confirm you can as i have done it ! however that farm is now a reptile center so not sure what the longevity has been like though .

i just cut the tube off the out side and used as normal reinforcing.

Did a grain store 8 years ago with fibres in it door way as well which gets pounding with lorry’s and six ton tele in and out a lot And has never cracked but it did have good base put in and rolled plenty
