Earth-moist concrete for curbstones

[Jonas1888]

I'm going to set curbstones and I'm trying to understand this thing with earth-moist concrete for backfill/fixating the curbstone.

Does it work to directly apply regular fine concrete in dry format completely without water? (i.e., instead of mixing cement and sand)

Also, how long should this cure if it is "dry" or earth-moist?

Grateful for input.

I have worked with dry coarse concrete. Wedges under the edging stone to get the right height and vertical.. poured on dry concrete.. then sprayed with water before filling. Turned out well.

I have used dry coarse concrete. Wedges under the curb stone, to get the right height, and vertically... poured on dry concrete... then showered with water before filling back in. Turned out well.

Thanks! Is the watering necessary or do you think it would work without watering?

I say differently,
earth-moist concrete must be mixed in a mixer with the right amount of water,
for at least 5 minutes before using it. Can't be done with a beater with earth-moist.
In this heat, post-watering is good.

It completely depends on the surrounding soil and its moisture...

Works to some extent, but you don't get the same strength in the concrete. And the powder that doesn't get water serves no function. I wouldn't do that at my home, but everyone makes different choices.

For me, the stones have been secure enough to function as edging for flower beds. They hold like a rock. If it's an edge you plan to drive over, then you might want to optimize its durability better.
