[@CptNtrps66]

How do you pull all that hose back or do you disconnect one at a time and if so how do you clean out the lines you disconnect? Compressed air and a sponge ball? Aimed at what? (I’m new to this and just trying to be efficient, I operate a schwing sp500)

Good afternoon, how can I get a job with you from Europe, I have more than 8 years of experience with a concrete pump. What can you advise?? thanks for the answer)

Years ago, I worked for a company that required all machines to prime out w bentonite. Thought it was strange to use it w booms, but did as I was asked. Ff a few years, a fella primed out in a panel... He bought that panel. Top corner from what I was told. Just gotta be careful. Personally did 770', all rubber, w bentonite. Works awesome if used properly

[@canadianconcretepumper1979]

We also made it our standard as stuffing booms up on the prime has been virtually eliminated ever since. It was a very rare occurrence, but also was VERY expensive the few times that a contractor decided to send loads of concrete away on the pump companies tab). We also had a guy prime it directly into the balcony area of a suspended slab….. that was a nice little $8K repair bill (could have been much worse actually).

It works fantastic as a priming agent, but definitely needs to be used responsibly.

Where can we buy bentonite?, I have a line pump here in nova scotia . We used prime a pack brand but it's expensive. Also we put our sponge in front of primer to hold it back , seems to help . We also tryed buying bentonite from a drilling company but it's not the same product plugs 30feet in . We have tried everything prime a pack is only one we can get to work , our concrete also sucks here

Attached is a link to the exact product which we use: www.wyoben.com/product/extra-high-yield-bentonite/

@@canadianconcretepumper1979 what size aggregate are you pumping . We use 3"line but we would like to use our 2.5"hose we can't our 1/2inch stone mix still plugs steady cant use any smaller the 3" and we still run into quite a few plugs

[@canadianconcretepumper1979]

@@duurrick most of our mixes are 1/2 stone and we pump them through as small as 2” hose. Mix designs here are also blended with smaller stone and plenty of sand. We used to see a lot of 3/8 round/river stone, but it has been hard to come by in recent years. That stuff pumped like a dream!!!!

[@GRUBB-MUDD]

i always let them play all the way fyi

[@princecharming5846]

What size stone do they usually use for line jobs like this? Maybe convert it to MM for me 😂 standard is 20 MM aggregate here and very rare we even use 3 inch.

[@canadianconcretepumper1979]

This particular mix is 14mm stone (which is most common for our “small rock” mix designs). Standard mix for the region is 20mm stone and we occasionally see do 10mm, and sometimes even 5mm for some of our architectural mix designs. Most of our 20mm mixes will pump through a 3” line, but our sand is natural and our stone fairly “gentle”. The line-pump mix which we most commonly use is a 14mm which we push through 2” line (200+ feet no problemo).

[@thisguyeddiex7136]

I noticed you don’t put any water before the bentonite, have I been wasting my water and time? Haha

[@canadianconcretepumper1979]

It really depends on the mixes/materials/setup.I typically do not, mostly out of fear that the bentonite will somehow work it’s way past the water and cause a segregation plug when the water comes in contact with the crete. This is all just fan-dangled theory though. If it works, I say keep doing it!

Where do you buy your bentonite?

[@canadianconcretepumper1979]

We get ours from a local drilling supply outfit. Concrete Pump Supply sells it pre-packaged as “Prime-A-Pac”. It is a bit more expensive than buying bentonite by the bag, but the individual sizes are a little more convenient in terms of storage and use.

@@CptNtrps66 Definitely checkout this one which I posted just yesterday. It’s probably my most favourite method for cleaning up the system at the end of the pour: kzbin.info/www/bejne/pGTUhnqDZ86ZbdEsi=idgJIQx3NY2npII7
