Hello concrete geniuses! I, a lowly homeowner, will be DIYing (likely by myself with no help) a large format paver walkway with poured/placed concrete. I know hiring a finisher would get me better results, but its not in the cards right now.

Here is the formwork I've already completed. I put a few inches of compacted 3/4 minus in as well, but not pictured here.

Most the pavers are 18x36 and will require about 1.5 ft3 (0.04 m3) per step. Total job about 1.5 yd3 (1.15 m3).

Is this a good project for bagged mix w/ an electric mixer? Would take about (3) 60lb bags per step. Maybe a fiber-reinforced mix? Or add some wire mesh to each step?

Getting a mobile mix would be better/easier, I'm sure. But, again, no help, and I'm nervous about being able to do the whole thing at once by myself.

Thinking I could do it in 3 sections in 3 days. Also, I was thinking about going for a sand finish using some sort of retarder that I could power wash off the following day, but will skip that and do a broom finish if you all tell me that I'm asking for trouble.

Do ya'll have any words of wisdom for me?

We have a week of lows in the 20s forecasted here right now, so think I'll wait until early March to do this when I know we'll stay above freezing.
