Blue Concrete Slab is a half-height block made from Blue Concrete. It is crafted by turning Blue Concrete into slabs, and it keeps the same solid blue look in a thinner form.

Players mine it with a pickaxe, and it drops itself when broken. It can also be waterlogged, so water can sit inside the same space as the slab.
