Wet concrete is caustic- it will burn your skin. Concrete DUST is not good to inhale- it may contain silica. Solid, cured concrete is about as hazardous as a rock.

Is asbestos harmful if used in water pipes?
Concrete pipes used to carry water were sometimes made with asbestos, which was used to stregnthen the pipe. Over years and years of water running through the pipes, some erosion will occur and asbestos fibers will get into the water being distributed - although in very low concentrations. If the use of water contaminated with small concentrations of asbestos is harmful, then asbestos use in water pipes is harmful. The problem is that there is no agreement in the scientific community as to whether asbestos in water at the concentrations observed is, in fact, harmful.

Does curing concrete produce any kind of gas?
