Minecraft Elegance: Practical Concrete Factory (Sand, Gravel, Powder, Flint, Java 1.19+)

An easy-to-build, slimeless concrete factory that runs safely on servers (45,000 blocks/hr). Dupes concrete powder blocks, converts them to concrete, and breaks them for collection. It can also handle sand, red sand, and gravel. Designed to automatically start and stop the TNT duper so that it doesn’t self-destruct. The player can start and stop the farm to reconfigure the duplicated blocks without changing dimensions.

FAQ: "Can you use both sides of the exit portal to increase the rates?" No, the block conveyor and block breaking system in the overworld is designed for 5 blocks arriving every 8 game ticks, so this would need to be reengineered.
"Does this dupe dragon eggs or anvils?" No
"How high can you build this in the sky?" As high as you want, as long as it fits under the build limit. You can start building around Y=300. This can be a good way to hide the farm.
"Can the pillar of temporary dirt blocks at world spawn be removed?" Yes.

NOTES
5:59 and 6:06 Examples where items of concrete blocks (green) are ejected from the block stream by the concrete column.
8:06 These items are concrete powder, not concrete.
9:30 I recommend connecting your world spawn to a stronghold by a nether highway, for example, on the roof.
13:50 One redstone tick = 2 game ticks, so 3 redstone ticks = 6 game ticks.
26:36 Players arriving at the world spawn have a chance of spawning around the edges of the farm and getting some damage from the TNT explosions. You can put a roof of leaves (7x13) over the farm to prevent this. The scaffolding gives a way to climb down.
26:42 This modification lets you configure whether to collect concrete or concrete powder. It also lets you collect without TNT explosions, for example, to collect gravel without flint.
27:15 A wither cage under the exit portal (e.g., for wither rose farming) does not interfere with the farm.
27:35 Tear down the gravity block duper and place the last end crystal on an obsidian to resummon a dragon.
27:52 Gravel can be converted into dirt by crafting coarse dirt and then using a shovel to make dirt path, which breaks to make dirt. An alternative is to till the coarse dirt to make farmland, and then breaking it to make dirt. A water bottle applied to coarse dirt makes mud, the same as normal dirt.

PAPER RESOURCES
Many Paper players have reported difficulty getting this farm to work, perhaps due to inconsistency in the gravity block duping with Gravity Control. If you still would like to try, some resources are listed below.
