Concrete blocks are now able to be made in the crafting menu similar to adobe,  can be upgraded from other blocks, including:
 * Most Brick blocks
 * Cobblestone Blocks

Upgrading
It is important to note that concrete - when initially upgraded - will be wet and therefore significantly weaker than dry concrete, giving less structural integrity and a lower durability until it eventually dries (over the course of roughly a day). For this reason, temporary supports need to be added when making higher level floors.
