Was thinking to use the Cement All by Rapid Set using some of their set control which gives it longer work time. Do you think this product would be okay? I think this product would allow for formless install as is. However, they also sell a plasticizer that I could use to do forms also.You can mix it by parts easily. For 5 10' sections i would personally form it if I was making the repair. Super easy and fast and I can leave the site with no worries or babysitting. Nothing fancy some thin plywood or whatever is laying around my yard this isn't pretty formwork.
I will head back out to HD tomorrow and look for some suitable wood to use as forms.
Attached some pictures of the rebar I installed. Probably could use some more pegs in certain places and maybe raise them up a bit higher. I did acid wash the bond beam today with 1 part muriatic acid and 7 parts water. Also began grinding off the old tile thin set using a diamond cutting cup.
