I just used JB weld to fix a part on a cast iron sculpture in my yard. Worked great and made it through a crazy winter too. I am going to use it on a cement piece that I broke removing snow. Should work fine, make a jig to support the parts in the proper position. Can be sanded after cured. Should be good as is but may want to store dry inside during winter season.

If you want to paint, clean and etch if possible and use a cement sealer.

Love the cement sealer idea. Will use JB weld. Need to get a syringe to inject.

They make static mixers for jb weld- syringe like nozzles that mix as you apply. I use similar at work for industrial adhesives. Works great. https://i.imgur.com/wKBIqoX.jpg

Should work great. If you have a grinder and enough access grind the opening of the crack a little bit to clean it up and allow better penetration. I also masked off the area around the break with tape to keep the epoxy off of the surrounding area. Be patient Let it cure a good long time depending on your weather. Warm temps speed up reaction time cold slows it down a lot. Good luck!
