Can I pour concrete around cast iron pipe?

the concrete around the post at the top (slab or patio) will cause two problems, 1 it makes a weak spot that will crack or 2 as the cocrete expands and contracts with the weather it could shear the post and cause the structure to fail.

Especially since it does not come in contact with the stove, but only gets heat from the pipe, any amount of heat from medium to high setting should do the job in around four to six hours. The general curing time for the fire cement is around 12 hours.

Typical concrete does not melt. It decomposes (usually before any one ingredient melts). Materials containing more than one ingredient do not possess just one melting point in any case. However, if you heat it hot enough, with a flux such as iron oxide, a glassy mess will form around (maybe) 900 degrees Celsius.

Then drill diagonally from hole to hole all the way around.

Well, you can use iron oxides and metal pieces or metal shot instead of sand and aggregates when making the concrete. That will result in a heavier concrete dumbbell.

To make a smooth finish on the cast we add several layers of joint compound and sand it down until smooth. This step takes many hours of labor over the course of a few days (to allow for drying time.) We can also do a textured finish if you would prefer.

Remove forms the day of pour and customize: Remove the step forms and finish the corners of each step the day of the pour, while the concrete is still workable.
