Oh, no way. There isn't a worry about it at this time. The major concern is the amount of CO2 that gets generate and the amount of water that gets consume. There is PLENTY of the other materials needed.
Also, they are changing the way that concrete gets made to reduce CO2 and water consumption. However, like anything else new it will require a long time to test out all the kinks to these processes.
We really should be trying to have more plants in the cities, to lock up some of that CO2. More soil and less concrete, glass, and metal?
