Chipped, cracked, and damaged concrete is a pain that no one has really properly address in this century.
Although there is a concrete patch with latex mixed into it that works better than any thing else on the market. The latex allows the concrete to give and it adheres to existing concrete pretty well.
I used this stuff last summer to repair and adhere my bird bath that fell and cracked and did chip also. I mixed this stuff up and the crack was fixed the chip went back into place and I am happy.
Give this a try. You might like it.
