Gray Concrete Powder is a gravity-affected block used to craft Gray Concrete, offering a neutral, modern building material in Minecraft. Like sand and gravel, it falls when unsupported, making it behave differently from standard solid blocks.

To craft Gray Concrete Powder, combine 4 Sand, 4 Gravel, and 1 Gray Dye in any arrangement in a crafting grid. This shapeless recipe yields 8 Gray Concrete Powder blocks.

When Gray Concrete Powder comes into contact with water—by being placed adjacent to, inside, or falling into a water source or flowing water—it transforms into Gray Concrete. It must land and be adjacent to water to harden; falling through water does not trigger the transformation. Rain and splash water bottles have no effect.

Placed beneath a note block, Gray Concrete Powder produces a snare drum sound.
