Quotes:
Ultra-high performance concrete (UHPC) is an enhanced fibrous and
cementitious concrete with high compressive strength (120–250 MPa)
particle packing density (0.825–0.855, tensile strength (15–20 MPa)
and extraordinary durability. UHPC has 300 times the ductility and
energy absorption of high performance concrete (HPC) and three to
sixteen times the compressive strength of regular concrete. About $500
million of the billions spent on the Freedom Tower was the UHPC
concrete. It has stronger material than the old Minute Man nuclear
silos. The large amount of UHPC has moved it into the mainstream
higher end option for skyscrapers, bridges and roads.

The Cost to Make a Building Fire Resistant Would be More Than
Committing to Ultra-high Strength Concrete for Better Protection.

Sounds like a good idea.  Is it feasible?
