Concrete Powder

Concrete powder is a solid block which comes in the 16 regular dye colors. Like sand and gravel, concrete powder is affected by gravity.

Breaking
Concrete powder can be mined with any tool or by hand, but using a shovel is the quickest method.

Usage
Concrete powder will fall when there is a non-solid block beneath it. If it falls on a player or mob, the player or mob will suffocate.

Creating concrete
If a concrete powder block comes into direct contact with water, it will solidify into a block of concrete. Rain, however, has no effect on concrete powder.
