How big of a slab could I do by myself?

Our local cement plant has a 4 yard minimum, so that doesn't surprise me that you didn't get charged.

Dunno what it is here, but up in Wisconsin, the local yard would deliver a minimum of 1 cu/yd on Saturdays for $89. It got cheaper per yard the more you got. Took advantage of that several times. Of course, this was in the early to mid 90's, and concrete isn't anywhere that price anymore, especially for a short load..

About 30 years ago I wanted to pour a small sidewalk extension to accommodate some pre-cast steps to go over the deteriorated original steps at our front door. I needed about 1/2 a yard, as I recall. The local yard had a penalty for anything under 4 yards. The penalty was the same price as a Harbor Freight electric mixer and enough bags of cement to do the job myself! That was my first foray into DIY cement.

I did in myself, it turned out fine, I still have the mixer and have used it a few times for fence and garage addition projects. Otherwise, it sits in the back of the garage waiting.

Another thing, that one form board... That is a side effect of solo screeding. Do, yes, im gonna pull the 2x6, but im gonna have to do some shady crap to fill that 1.5"×5.5"×6 ft gap, not going to leave the board; but i also wasnt fixing to screed an 18ft wide section

Would like to hear how you deal with that joint. I have a place where the slabs have separated about that much and I'm trying to figure out how to fill that gap. I guess I could just stuff it full of foam and pour elastomeric sealant in the top 1/2" or so, but not sure if that's the only/best way.

Im thinking about double stacking expansion joint, and using polybulatyle caulk; but i might get some non shrink grout instead. Either way, it sounds like a not today problem

On wide cracks, ive seen multiple fixes; ranging from cut and replace, epoxies, to "great stuff" expanding foam, cut off and caukked over. Epoxies are great, but they are Dang expensive. One "fix" ive seen tried several times, but never hold up, is grind it down skim coat over the top. Doesn't seem to matter what bonding agent, high strength grout, ect you use, skim coating with 1/8" to 1/4" just doesn't hold up, even to foot traffic
