Material science is all about choosing the right material for the right job. And if we can't find the right material, we can always modify it. Here we see a solution to the problem of airport runway overruns.
The requirements - as mentioned in the video - are things like fuel fire resistance, low cost, access to emergency vehicles, ability to withstand jet blast, limited damage to the aircraft, replaceability. and durability through freeze/thaw cycles. The solution given here is a composite of cement designed to slow the aircraft as the Emergency Material Arresting System (EMAS) is destroyed.
