Getting set concrete out of 3 inch rubber.

Gday guys, Australian concrete pumper here. I just found this site and look forward to becoming a member of the community. 

 

I come here with a question to help a fellow pump owner. Between the combination of a super hot day and a horrible mix of concrete with high dose accelerator, concrete had 90% set in a 60ft length of 3inch hose. (line pump). He managed to bash, shake out and save about half of it, but the rest has set. It has been a few days and he has had not much luck with it. Is there anything that can be done or is the hose gone? 

 

Thanks.

run the hose over with a truck and chisel the end of it out with an air chisel

I agree with the above. It works. I drove my hard tire fork lift over my then hung the hose from the forklift and started flushing it out. Didnt damage the hose either. Sometimes low tech works.

But guess you will have to loose the steel at one end... Not sure if the above trick will still work after a week though..

Running over the hose scares me.  If you damage it and one day you pressure up and it blows what could happen.  You might save it but at what cost.

Ive gotten out some pretty hard concrete with a garden hose with good pressure and a blow out cap. but we did it that day, not a couple of days
