I'd like to erect a small shop about 20x30. This might be a timber framed structure. I have a backhoe to dig for footings and foundation. My question is about the concrete. I have an access problem for big trucks, so I'll have to mix the concrete myself. Is it reasonable to think that I can mix and pour from a 3pt mixer and end up with it done right?

What about a pole barn no "footings" just PT posts in the ground?

what art you putting on the floor?
what is the issue with cement truck size, weight, roads?
site mix truck or a mini truck might work.

Another option - at least in our area - are smaller concrete trucks. These are great for areas where access is limited. While doing the project with 3-point mixer is very viable, this would be my second choice behind two trips with the small truck mixers.

There was a pile of concrete poured before Concrete trucks came into being.:D

Just remember its hard work and requires placement planing so the batches are coherent. It's very labour intensive so a crew is always advisable.:D

Pumper truck?:D
small cement caddy? [tractor bucket]

cement caddy = mud buggy around here.
another option would be to pour 12" piers where you're going to have upright poles set.
these would be easy enough to do with a 3 pt mixer and no worry about cold joins.

I agree with Egon,

Pumper truck.

As much as I like doing everything myself, I've learned sometimes you have to pay a little more to save yourself alot of work and headache. I had a friend that lives in the city pour a 25x50 area of concrete, BY BAGS AND HAND MIXING. Never again. Pumper truck will be quick and save you alot of aggravation.

You will be there all day. We poured a 12x8 slab 4" tick with a mixer and 4 guys and it took 6 hours. Really, just do the pole barn or have the concrete pumped.

No.

Concrete is going to be drying on you faster then you can mix it and spread it out.

As for how did they do it before concrete trucs were available, in allot of cases, they didn't. Look at allot of old buildings and you will see pier and beam foundations and/or wood floors. In a few examples where it was done, you'll see that it took allot of manpower to accomplish it. Multiple mixers and people hauling it back and forth.

In theory, with enough people, mixers and wheelbarrows, it could be done. It would have to be planned out, laid out and organized. That alone requires experience in order to have enough material on hand and that it's spread out before it hardens.

United Rentals has one yard buggies that you rent and pull behind your vehicle. They have gas motors that keep the mud mixed and allow you to tilt it to dump it when you back up to the pour site. One yard doesn't go very far, and you have a pretty big pad to pour.

Depending on your location, you might need to dig down pretty deep for you footings.

You could pour just the footings and then fill the pad in smaller squares to get a concrete floor. This makes getting it flat easier, but it requires allot of planning and engineering to make sure it stays flat and level. Things like freezing, moisture and soil types will dictate on what you use under the concrete for a base and how thick it needs to be.

Or you could build a pole buildings and leave the floor dirt, or add gravel at a later date.

It's real easy to get in over your head with concrete. It might look simple, but it's a skill that takes practice to be able to do well. It's backbreaking work that will wear you out long before you are done working it, and it's unforgiving. Make a mistake, and you have to live with it forever.

Good luck,
Eddie

I didn't think of the army of people approach.

But you still have to get the stone, cement and sand there by truck.

whats the biggest vehicle you can get there?

I helped a neighbor as a kid he couldn't get the cement truck to the forms but we could get his pick up there so we loaded pick up bed 3 or 4 times (tar paper in the tailgate gaps) to make pour and truck was way over loaded you could steer with one finger and it wasen't power steering.

Do you have a tractor with a loader or a skid steer?

Have the concrete truck dump into your bucket at the end of the driveway and take off.

Good Luck,
