"Death Seal"

I’m an architect who offers paid consultation services online. One day, I received an anonymous question: “Can a body be completely sealed in concrete?”

I replied, “No, concrete expands and contracts with temperature changes, which creates gaps. Additionally, as a body decomposes, it produces liquids and gases, which will eventually break through the concrete, causing cracks.”

The person asked, “But isn’t concrete really strong?”

I answered, “Even so, it wouldn’t work. You’d need to first install a waterproof barrier, a gas-proof layer, and properly design expansion joints.”

I ended up designing a whole set of structural details for how to perfectly integrate a body with concrete. The person seemed pleased with the design and asked if I could give it a name. After thinking for a moment, I decided to call it "corpse concrete," inspired by the term “reinforced concrete.”
