Go to a library, and look it up. O.K. you might need to go to a library at a school with an architectural or structural engineering program. Failing that Google Scholar list over 3,000,000 articles in a search for "concrete impact resistance". Most of the newer ones deal with fiber reinforcement.

As for your issues:
1. yes people have tested the idea, the result is that you need a relatively even mixture of your aggregate throughout the concrete. In a wet pour a hole sizing that is close to the size of the aggregate does not allow the aggregate to free flow, causing it to collect near the mesh. It works in stucco because it is used as a lath, something for the concrete to grip onto. If it were layered into wet concrete it would probably work well, but then you are vastly upping your labor requirements.

2. I completely agree, but you have to keep the aggregate size in mind too. it has to work as a system.

As for Rhino lining for blast protection, I don't know who would have said that as the same basic principle has been used since 1936 in car windshields and windows.

Sorry but roof and foundations not being in the scope isn't completely obvious. Sure you want to increase the strength of concrete, but why? For tornado resistance? If so what are the goals? To reduce rebuilding? or protect the occupants? That is what defines your scope not material properties.
