High-density concrete for bridge design
MagnaDense enhances stability and balance in bridge structures. It can be used as loose ballast in pylons or caissons to increase stability, or as an aggregate in high-density concrete for compact counterweights and additional weight in suspended structures, bridge decks, or landing heads.
Applications in Bridge Structures
MagnaDense is used in bridge applications where weight, stability, and balance are critical, including:
-
Counterweights for movable bridges
-
Ballast in pylons and caissons
-
Bridge decks and suspended sections
-
Landing heads and support structures
By achieving the same mass in a smaller volume, MagnaDense supports more compact designs, reduces material consumption, and enables innovative bridge concepts. In addition to improved structural stability, MagnaDense-filled high-density concrete also offers greater design flexibility.
