Zuckerberg is Making a Bunker But Bomb Resistant UHPC Buildings Could Become Common
by Brian Wang from NextBigFuture.com on (#6JCHY)
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. A $100+ ...
