Anyone ever pumped a mix like this ? Pumps pretty good through 5 inch. This is from a job I did last year

Just from the different SIZES of rock that looks like it might be a crappy mix.

Holy crap... Is that concrete??

I'll bet it pumps good through 5" line but I wouldn't even try reducing to 4"

i wouldnt want to kill my pump with that crap remember pipe have to be three time larger than stones

I pumped this yesterday with my Cifa 31

Guess were the only ones .. lol

Yeap. Lol. The concrete plant told me they had problems with the sand ( like if there was any in there). What a coincidence, they have the same problem every time I pump with them. 

 It actually looks similar to the shit I pumped for a radiation room last week, but the aggregates in your picture are not even close in size, be careful.

Looks like a "No sand mix".

have you guys ever pumped a no air mix???

We pump no air mix all the time , and they don't look like that, that almost looks like impervious mud, but we do from time to time have bad mixes , the putz's and concord will eat it up, Cifa's seem to have issues pumping them.

will simply stay away at the view of this "shitt"....

I have pumped a 2inch rock like that through a 43 Concord. But ugly crap indeed. She did good, I was pretty leary though.
