If you have concrete steps the chances are that one day you will have to repair those steps. Like virtually everything in life concrete is not forever and the day will come when it will exhibit its mortality. The question becomes, how do you fix them? A lot will depend on how bad the damage is and where that damage is. If your damage is similar to the damage shown in the first photo the repair is fairly straightforward and relatively simple. The materials you use will depend a lot on your preferences and your wallet. The repair seen in the photos was done using a rapid set mortar mix which allows for the project to be done in an hour or so. If using a standard mortar or grout mix one must allow for setting time before proceeding to the next layer (if dealing with a deep repair requiring multiple layers). The repair in the photos was done to maximize long term success. Steps such as using Tapcons (concrete screws) or a bonding agent could be eliminated if one so chose.
