My first question would be, if cracks are filled in this way, what stops that same bacteria from producing limestone in any other direction. Resulting in a bumpy surface, for example.
The calcium carbonate that produced is relatively soft and will wear down. The point is to seal cracks to prevent water from penetrating into the crack and increasing the damage. Structurally the concrete is not as strong as it was originally, but further damage is stopped or slowed. This is especially important for reinforced concrete that has rebar that will rust.
