Yes, it can come in contact with concrete.
Yes, there can be a chemical reaction between PVC and concrete, particularly in the presence of moisture. The alkaline nature of concrete can lead to degradation of the PVC material over time.

PVC does not react chemically with concrete, but PVC has a very large dimensional change when the temperature changes , so pipes that are carrying warm water expand. There are products available to wrap pipes going through concrete so that they have room to expand and do not wear through from grinding back and forth against the concrete as they expand and shrink.
I was in the PVC pipe manufacturing business for over 30 years and have never heard of a "1K PVC" pipe. If "1K" means a 1,000 psi pipe, this does not exist as a commercial product. Sorry.
