Fly ash brick (FAB) is a building material, specifically masonry units, containing class C or class F fly ash and water. Compressed at 28 MPa (272 atm) and cured for 24 hours in a 66 °C steam bath, then toughened with an air entrainment agent, the bricks can last for more than 100 freeze-thaw cycles.
Blast walls perform best if the explosion is relatively close to the front of the wall [1] "Canopied" walls (with a top section overhanging the front face) show some improved blast protection over plane walls; A 90-degree canopy is more effective than a 45-degree one [2] Walls containing sand or water work well, and cause little damage if they fail
