I was looking for brick pavers recently and was having quite a time locating actual bricks instead of cement pavers colored badly and textured worse to look vaguely like bricks to nobody sober during daylight hours. I can only assume their target audience is a drunken man, at night, in a rainstorm.

I have to wonder why we are still looking for new ways to employ Portland cement at this point, over alternatives. You can, I’m told, reduce the footprint of clinker a bit with fly ash, but you get that mostly from coal, so it’s splitting the “savings” with an equally problematic cousin, and at any rate that supply should be in steady decline now, although I guess we discovered the Tennessee Valley Authority has stockpiles of the stuff when they lost one of them a decade or two ago.

I am not an American but I am not sure I have even seen a paver made from brick now that I think about it. I suspect the larger a brick is, the more chance of cracking.

So if it makes you feel any better, you probably would not find one in New Zealand either.


Seems clay pavers are still out there. Here's some in NZ:

But I don't think any national chains carry them anymore.


You can also supplement with iron slag cement and silica fume from iron and silicon production, respectively. Those are probably not going away.


False. It's common in volcanos. It's why Roman Cement is so good. That, salt water and pig blood.
