Concrete quality: saks of Sakrete

The bagged products are subject to numerous user errors.

The delivered product is almost certainly mixed by someone who knows what is going on.

I suspect the reputation of bagged mixes has to do with Mr Mixer, not the mix.

You know, you can run a lot of tests on your concrete work yourself. Google "Gillmore tester", "slump test", and the like. Take juice-can samples and test them in your shop press for compression.

And is mixed in a truck designed for just that purpose, not in a wheel barrow using a shovel and a hoe. The driver needs to add the right amount of water and mix for the necessary period of time.

Maybe (I dunno one way or the other) a mix richer in cement is more forgiving to those errors.

Especially if you consider that fence posts are often set by pouring the mix in dry and then soaking it.

sakrete appears to do a good job, as long as its allowed to cure propperly and finished ok.

not like a buddy who laid his in the sun on a 90 degree day, never moistened the surface just rotted off:(

That is called "spalling". The top dried out before it cured and broke the bond with the center. Concrete should really be kept wet for 28 days to reach the design strength but usually a week or so is OK.
