Sometimes when we pour concrete floors the load of concrete seems a little rocky. This was one of those times. We usually order the same concrete floor mix on all our residential concrete floors. It's a 3500 PSI mix with 3/4 aggregate, micro-fiber mesh, water-reducer, and non-air (for interior floors).
Most of the time, the concrete mix seems nice and doesn't separate. Today on this job, the concrete mix had what seemed like too much stone.
I don't batch the concrete so I can't tell you the exact reason this could happen but maybe some stone got in the sand bin when the loader operator was loading the bins at the concrete plant.
Anyway, take a look at how we poured this "rocky" concrete and the tool we used to help consolidate the concrete.

@ 11:41 Glad to see the driver speak up. Our company policy is that the water is the drivers water and the let the customer use water as a curtesy .
the banter is the best part of this.. glad that driver always gives it right back to ya’ll. 😂
I am watching your vids from Europe/Hungary. You guys always do a nice job. I think US is strong at concreting.
Thank you!
Our concrete here in wa state is practically always that rocky. I am always jealous of the concrete I see online...
At my plant, when we run into those issues. It usually has to do with segregation before the batch. I'm not sure what course agg they use. When I let my bin run too low when batching, I have this issue. He more than likely has changed something small and hasn't noticed it being an issue. Repeatability is the key to good, consistent concrete. Everything the same all the time.
I agree, consistent is the key.
Since watching your videos. I now use the easy mix also. Because only 2 of us.
Gradation of the agg has a huge effect on mix performance. If the 57 stone is running too heavy on the gradation, you end up with that segregation
Must have been Robertson Mudd lol
That concrete basement wall at the lower side got hit by something like an excavator or something (around time 8:50). It really chipped the edge of that concrete wall. Wow... That's not your problem though. The floor looks good. You go man...
Definitely looks like too much rock in the mix. Could be their aggregate scale is messed up (rarely happens). But from experience sometimes your rock bin will get stuck open and overshoot your rock weight. The right answer is to remove the excess rock from the scale. But if you’re very busy that day they might of just said screw it and sent it anyway. More rock means that the cement has more surface area to cover too. Ask for batch weights to prevent this
Haha will Dewalt get a strop on with you advertising all these MBW Tools 🤣
The company you do these floors for do a really nice job with the basement walls,
Another Day on the job, "Problems" Just have to Roll with it, The Wheels of Commerce Don't Stop, they'll still be Spinning Ater we're Long Gone! On to the Next Slab 😉
A rocky road but not an ice cream. Just more work.
will that floor get more finishing , or is that i ,,, ??
It'll get power troweled for a smooth finish
@@MikeDayConcrete many thanks ,,,, could it be done by hand too , or is it only by power that gets the finish that smooth ?
looks like an 8 inch slump ?? thats why
It's supposed to be, it has water reducer, we pay extra for it to get a loose slump.
With high range water reducer in the mix, you can safely pour a 7 inch slump. He explained this at the beginning of the video. Most people who haven't seen a slump test performed don't really know what slump they are actually looking at. High range around me is also called super plasticizer. It makes the concrete look a lot wetter than it really is.
I didn't see those Dewalt mags ?
This was before I got them.
Mike, can you help me fix my salt damaged driveway?
It depends on where you are
@@MikeDayConcrete Its in Minnesota.
Three or four yards, 🤣🤣🤣
I dont like that super watery concrete....I think it makes for to many shrinking & cracking problems in the future.
Uh, our mixes have water reducer so we can loosen them up like this. They have less shrinkage than regular concrete.
