Sort of a general construction question: Aside from the physical forces of gravity, and re-bar, is there a chemical reaction that fuses different 'pours' of concrete together?
Specifically in regards to the foundation columns that have been recently dug out. Clearly the caissons are cured (mostly), and although new rebar will be tied to the existing rebar, will there always be a joint, however minuscule, between the top of the old column pour, and bottom of the new column pour?
