Subject: bullet proof concrete?
A friend of mine is asking me what kind of concrete would be equivalent to a UL 752 level 3 bullet proof rating, they are thinking of replacing a compressed ballistic grade fiberglass roving with something cheaper in a new construction project. Perhaps some kind of masonry would also be an option… I am not familiar with hardened construction standards, is there a resource out there I could look at? Any experiences to learn from?
