3 yards extra is better than 3 yards short. That is a good looking pour. Will you be sealing it, polishing it or epoxying the floor at all?

No, I had them finish it to this level so that it would still have some texture/traction. I just want it slick enough to drag stuff around on but, not so slick that if I spill something on it it becomes slippery. I'll be doing some maintenance on equipment and vehicles in here but, primarily it'll be a welding/fabrication shop.

Did the same thing with a shed pour, made an 8x8 apron in front of the doors with some loose 2x's, no wire or rebar or anything. It has since had a 20 yard dump and a concrete truck roll across and break it...but all it has to do is keep the weeds down and give me a flat spot to work on my mower, and it still does that even broken so I am still happy with it.

I had about 20 extra pieces of rebar from the slab, we cut those in 1/2 and dropped them into the concrete for that patio after it was poured. It's not the right way to do it but, better than no steel. I agree with you though, it was a bonus so if it cracks, I'm not going to be too upset about it.

I am surprised the whole country has not gone to front unload mixers
They are sooo much more user friendly

Nice project!!!

I have a tremendous amount of respect for "Concrete Guys". Their willingness to work always amazes me. I enjoy watching a good crew. Then the icing on the cake is the finish work. A casual glance at the pour by the right person determines the start of finishing. I DO NOT have that talent. :)

I absolutely agree with you on all of that, especially not having the concrete finishing talent. I did a couple of patios in our last house, none of it turned out the way I wanted it to because I missed that finishing window. Concrete is definitely a highly skilled trade.

And my expectations ALWAYS exceed my ability....... :)

Congrats on the pour. I've never waited more then a day or two to start framing and always take off the forms the day after the pour. Nothing wrong with waiting longer, but if I remember correctly, you are somewhere at 90 percent cured in a couple of days, 95 percent after a month, and 98 percent after a year. While I'm sure that's not completely accurate, it's close enough for understanding how quickly the slab is ready for working on.

Concrete gets 75% of it's strength in the first 24 hours.
Full cure is achieved at 28 days.
Easy to remember! That 28 days has some other meaning as well!

In actuality concrete continues to cure for around 100 years, granted at a very slow rate but it cures for a very long time.
They say that the Hoover dam is still in its cure phase

Well that's because of all those bodies embedded in there.....

Sorry, couldn't help it.

I agree concrete cures very slowly. In the first 30 days you better refrain from dropping heavy sharp objects on your shop floor. :(

My shop is 7 years old. I work on it almost daily. I haven't noticed a distinct difference in a couple years. The first five I did.

The charts I've seen seem to agree that 7 days is the spot where things start to level off. I've left the forms on and they added some chemical agents to slow curing a little. I've also been wetting the surface a couple of times a day to reduce the heat and increase strength.
