How many yards of concrete do I need?
I am building a new range house. I need a slab 3" thick 24 feet by 12 feet. How much concrete do I need and could I do it with Sacrete in sections to save the truck charges?

i'm getting 2.3 yards. go the truck route and have fiberglass mixed with the concrete and pour in 1 setting//quikcrete charge would be a ton of work and expense even if you broke the pad into sections. sections also increases the likelyhood of pads floating uneven over time. be sure the sub layer of ground is compacted prior to pouring 0 -
You could do it with sacrete but you don't want to. The truck is so fast and easy.

At 3" thick you will need 2 2/3 yards of concrete, order 3 just to be on the safe side. You would need 108 eighty pound bags of of sackcrete for 2 2/3 yards. 0 -
2.666666666666666666 yards. EdZachary.
Are you going to be building anything over it? If so you'll need to thicken the edges/support points pretty substantially in order to support the structure.
As far as Sackcrete goes, PAY THE TRUCK CHARGES!!!
You'll kill yerself mixin' that much mud, even with a mixer, unless you have a lot of good help.0 -
Don't use Sakrete. 0 -
After mixing 100 80 pound bags of Sacrete,the truck charge will look like a bargain. 0 -

Especially when you are about 1/2 way thru.... Who's idea was this to use the bags?3 -
I did a poured concrete foundation for my log cabin 4 years ago.
The concrete truck, and the pumper truck, are your friends.0 -
Use wire and lots of cuts. It will crack so decide where by cuts. 0 -
Concrete is designed to crack As someone suggested, order the ready mix with "fiber mesh" and yes, thicken the perimeter of the slab maybe 12"X12" and put a rebar of two in there. After you pour it keep the surface damp for a week. Just a sheet of visqueen and spray with a hose once a day.0 -
the fiber mix is the cats ass for keeping down cracks
I did my pole barn 30 + years ago only a couple small cracks have ever showed up
when younger I was involved with so much concrete pouring and it had to be high slump (real dry) to pass inspections on majority of it dragging and pushing it place was no fun with a concrete rake or comalong as we called them . pump trucks made some easy but the slick lines were a pain ( the steel tubing to push the concrete thru ) I will say I did enough for two lifetimes LOL my screw up back and Knees will agree and add in concrete poisoning is no fun trust me3 -

your right memory slipping I remember the inspectors doing there test temperature slup and so on when it was " correct" it barley moved when the pulled there test cone off . had one inspector who was more worker friendly said he would be dead and gone before any of it failed so add the water LOL3 -
The company around here will not deliver less than 4 yards. Well, they will, but you still pay for a minimum of 4 yards. 0 -
That brings back memories. I was involved in a lot of concrete pouring back in my working days. I was a field engineer and later a construction superintendent at TVA's Widow's Creek Steam plant back in the 80s and 90s. The plant was out in the boonies in NE Alabama and every time we were pouring concrete we had to get someone from the office in Chattanooga to come down to do testing. So the plant manager told me to go get the ACI Laboratory Testing Technician - Level 1 certification so we didn't have to wait on them anymore.
I figured there wouldn't be much to it but it turned out to be a whole day of testing at one of Ready Mix's offices. I had to spend all morning in class and then there was a 2 hour test with 100 questions and then we spent the whole afternoon out in the field doing actual concrete testing. It wasn't all that tough but 25% of the class failed. I had studied for the test so I passed. I was glad I did because it would have been embarrassing to go back to the office and tell them I had flunked. I think some of the guys there hadn't even bothered to study thinking there was nothing to it.
I set up my own little lab in one of our construction gang shacks using a cattle watering trough wrapped in insulation with a styrofoam and plywood lid to keep my cylinders in lime water in order to cure. I used an aquarium tank heater and thermometer to keep the cylinders at the correct temperature. TVA had a testing lab where I would send the cylinders off to be broken since we had a truck going to and from Chattanooga everyday for the warehouse.
I hadn't thought of that in years. Seems like a lifetime ago.3
