You can make cobblestone rocks from day one with just a stone axe and shovel.
Flagstone (500) Cobblestone (1500) blocks, to let you make your base where you want it.
Or at least start on it. also, can be used to patch up a POI (the walls of say, Zoe's Salon)
You can make the 50 Pillars to make a cage to fight zombies from too.
Upgrade to concrete/reinforced concrete later on, and by then, can go right to reinforced concrete for the blocks.
wood frame, block, reinforced, scrap iron 1, 2, 3 then concrete. And it takes a LOT of iron to get there.
Sometimes I'll beef up a POI for a while, other times, I'll not bother, and just save up the mats to get started on my own, but waiting to get enough concrete.. hmm.

Er.. Concrete has PSI strength indexing. If you want a nonzombie real world conversation about just what this means you can always watch Locke where he's talking to his buddy on the jobsite. It's possible without tension rods to get super high PSI concrete depending on what you mix into it. Just like you can change it's aqueous nature (for underwater building in the real world) and flexibility so that it doesn't shatter when the earth moves a little (see any building in LA.) It is much stronger than natural stone depending on how it's mfg'ed and what you add to it. The game doesn't get that wrong, it just lets you do it with simple materials rather than requiring you to go full chem engineering.

In case nobody put this down in reel life u have different kind of stone/rock u got sandstone, lava rock, granite, granite being the hardest I just mentioned, and then u halve different kinds of cement, assphault is tecknicaly a kind of cement cement can be reinforced with rebar or I beams even metal pipes whitch makes it support more weight and also mor durable in that when it gets hit something it will just crack not shatter or depending on what happen the concrete will not support the wall but it will still be standing because it's also supported by metal rebar, ect. It's harder to put Supporters in rock then it is to just pour concrete around rebar in a wood mold/frame. But wonce dried it's has the same hardness ass stone or stronger depending on the rock u used as your cement mix. So basic concreat blocks are just made out of stone and nothing else so thay have the same durability but when they are reinforce by metal rebar or even just poles in the cement mold once dry they are even more durable and in real life won't crack under pressure like regular concrete will

It does seem odd that zombies can bust through concrete walls.
I understand its a game mechanic, otherwise, we'd get bored watching oceans of zombies break themselves on our concrete walls.
I think it would be cool if we tracked how many zombies were killed by the player after they touched a concrete wall. Then we used that count to trigger the spawn of a wall busting type zombie.

That used to bother me till I saw two documentaries [not related to each other... so I thought.]
One was of a real guy called the Iron Fist. Turns out he lived not far from where I grew up.
Famed for punching a board one thousand times each day.... each hand.
The callouses on he knuckles were 1/4 inch thick and he really could punch and break brick and weak concrete walls.
Then another documentary about animal horns and other things we think are bones but aren't.
A rhino's horn is made of hair yet can pierce and take a car apart.
So bearing all that in mind.... let's just say the zombies grow hairy horn-like structures on thier body allowing them to not only absorb more damage, but giving them the ability to smash concrete and even steel.
Yeah it's a stretch but.... hey we're trying to apply logic to unicorns here.
Gotta give me a little slack.

Or you go the other way and create larger Mutant zombies that are good at busting walls.
I did such a thing on my server.
Made a ton of custom zeds that specialized in one particular thing.
The "Boss" could, of course, do it all.
Even steel walls were at risk when these baddies came by.

It can be manufactured in a cement mixer. Why - I don't know. But you can. And here's the cost comparison:
[table=width: 500, class: grid, align: left]
[tr]
[td]Block name[/td]
[td]Raw material cost[/td]
[td]HP[/td]
[/tr]
[tr]
[td]Stone[/td]
[td]10 crushed sand, 22 small stone(4 in cement)[/td]
[td]500[/td]
[/tr]
[tr]
[td]Concrete Block[/td]
[td]10 crushed sand, 30 small stone(10 in cement)[/td]
[td]3000[/td]
[/tr]
[tr]
[td]Reinforced concrete Block[/td]
[td]Concrete way: 20 crushed sand,60 small stone(20 in cement)
Rebar frame way: 10 crushed sand, 30 small stone(10 in cement), 5 iron, 1/5 lump of clay[/td]
[td]9000[/td]
[/tr]
[/table]
Just going by material costs, effort put into and workstation needed for the block's creation, I would prolly agree that stone should have somewhat higher hp, close to that of first stage concrete. Or a more balanced recipe.

That's just an issue with the XML format in the game. Each material type, eg(stone, metal, wood) has an associated structural intergrity, and it's a pain to change that stuff away from that. Last time I checked, landmines had a structural integrity of 320 because they are made of metal.

Doesn't make my point any less valid.
Recipes should reflect that.
On my server players can craft:
- Riveted Bridge Metal
- Bridge Concrete
They have stability of 400 allowing for longer spans between support pillars.
They also require more resources than Reinforced Concrete.
I don't see that scaling between other materials.

No, I don't disagree, it's just that SI balancing is not at a very high priority right now with the developers. I think it's cool that you have the extra-string bridge pieces. I don't know how much this is common knowledge, but it's also possible to nearly quadruple a bridge's length between pillars by building it as an arch fit to an exponential curve.
Like sargentcobra said, there are different kinds of stone. The stone you find just below the surface could be compared to a sedimentary rock like limestone which isn't nearly as hard as an igneous rock like granite that you could imagine is what bedrock is made of. Cement is made primarily from limestone. Limestone is 3-4 on Mohs hardness scale, concrete is 4-7, and granite is 7.

This.
Something to think about, concrete super bases would be harder to build if solid stone was harder to mine, but also less tedious because the player would be encouraged to use other methods like searching for destroyed stone deposits or boulders.
IF you were to assume that the Mohs hardness scale reading is roughly proportional to the time for a zombie to break through a material, those numbers you gave would not be enough to justify the 6x durability diffrence. However, which material property to apply depends on the method that zombies use to break stuff. If they claw through stuff, then hardness is an effective indicator. However, if they do the "super punches" like what Lucky suggests, then a material's toughness(energy per unit volume that a material can absorb before breaking) is the metric to use.
-------------------------------------------------------------------------------------
On another note, I think I figured out the real reason for the drastic durability difference(D.D.D.). In A14-ish and before, mining stone did not yield small stones like it does now, instead giving players the stone in block form. This meant that players could use it as an easy building material, so it's damage resistance had to be nerfed.

Get the [bleep] out of here! Are you serious?
Engineering has always been a fascination of mine.
I don't suppose you've got a link to a vid of an example.
I'd love to see that in action.
Perhaps when I'm done my current game I'll give that a shot.
Always wanted to make a castle with an adjacent tower and some really cool medieval arched bridge over to it.
