Concrete

Breaking

Concrete requires a pickaxe to be mined. When mined without a pickaxe, it drops nothing.

Natural generation

Red and white concrete can be found in trial chambers throughout many various murals in an atrium.

Post-generation

block falls through the water, while the concrete powder instantly solidifies on contact with water. (Click for bigger video view area)]] Concrete is formed when concrete powder comes into contact with a block of water (source block, flowing or waterlogged‌). If next to a waterlogged block, it must be adjacent to the sides where water can flow out from, such as the open sides of stairs, but not the back side of stairs or any sides of waterlogged leaves.

Renewability

Concrete is renewable as all of the crafting ingredients of concrete powder are renewable. However, without glitches, sand is renewably obtained only through the wandering trader, which spawns infrequently and allows a limited number of trades per spawn, making it impractical to obtain sand (and by extension, concrete) through renewable means.

Usage

The bright and solid colors of concrete make it useful for decoration. It has more pronounced colors than stained terracotta, and unlike wool, is not flammable. As a building material, its hardness is slightly higher than stone, but its blast resistance is significantly lower.

Trivia

In real life, a 1-cubic-meter concrete block (the size of a block) is practically blast-proof, while the blast resistance of concrete in Minecraft is quite low. A black concrete block is considered the darkest block in Minecraft.
