Is this compliant, yes or no?
That can easily be determined by grabbing and shaking the smaller pipe.Short answer: yes if the sleeve was intact when the block wall was grouted, no if it was broken during grouting so that the pipe is grouted in place.

Any material weaker than the pipe, so that if a load is transmitted from the wall through the material to the pipe, the material will crush before the pipe does.What is used to seal the annular space and not lock the pipe in place to the point that the pipe could become subject to a load from the building?

Yes.Is it truly 2 sizes larger?
