  • Insulating Concrete Forms (ICFs)

    Insulating concrete forms systems can vary in their design. "Flat" systems yield a continuous thickness of concrete, like a conventionally poured wall. The wall produced by "grid" systems has a waffle pattern where the concrete is thicker at some points than others. "Post and beam" systems have just that – discrete horizontal and vertical columns of concrete that are completely encapsulated ...

    Several fatalities have occurred recently in South Korea as a result of fragmentation due to the collision of a vehicle with a concrete median barrier. The current impact level of a concrete median barrier (CMB) is SB5B (270 kJ). However, the impact level of the collision was estimated to be over SB7 (2,300 kJ). Inspired by this, many engineers agree on the use of improved CMBs to reduce the ...
