Pumping 6000 psi with 2% non chloride and hot water. After waiting 2 1/2 hrs for a fresh load I said enough and washed out and just reprime and start when new truck gets here.Just when I start to wash up truck shows up. WTHF. Just playing it safe .

your truck, your call. not your fault the mixer diidn't show for that long. suprised you waited that long with that type of mix design. mud must have been just cookin'. she come clean alright?

Just playing it safe ended about an hour and a half before you washed out!!..You were trying to do them a favor and hang on for as long as you could!!But when the time comes,The time comes!!Rinse that pig out and start over!!!!!I would say you were the hero,and RM was the bad guys!!! You did way the right thing.Both by waiting ( A little longer than I would have perhaps) and by washing out!! (not as soon as I would have)..LOL

Had to do this last week...old concrete, 2% and hot water...when its time its time...for sure the right thing to do.

yea good call dude pump comes first as soon as your done the job they leave you there god forbid you have a boom party they would go to lunch contractors oneway as they come

ah yes the life of the linesman, what i usually do is start to have lunch after the 1st hour, and shazam, two bites onto it and here comes the truck, if i finish lunch i start to wash period.

bad guy, dont think so, bad would have been beating on hose and not being able to finish.

One thing I preach in the school is this; Understand your machine, know when to wait and when to clean out, so many times operators wait until it is to late to clean out then the mud is to tight to clean out. It is easy to prime up again, never be intimidated into risking delaying cleanout. It is not backing out, it IS being educated and under control. The operator is the one being paid to do the pour and make sure his unit will do the next one also. I would back you up you did the right thing.

WHAT I DO WHEN DEALING WITH MUD THATS A TIME BOMB.HAVE THE RM DRIVER OR THE CONTRACTOR CALL TO FIND YOUR NEXT TRUCK.COURSE THEY'LL TELL YA IT ON THE ROAD WITCH IS A LIE.THEN TELL THE CONTRACTOR YOU'LL GIVE HIM 15 MINS. THEN YOUR WASHING OUT.TELL HIM YOUR TRYING TO WORK WITH HIM BUT I HAVE TO SAVE MYSELF TO FINISH YOUR POUR THAT THE CONTRACTOR DID'NT PLAN RIGHT.YOU DID THE RIGHT THING, SAVE THE PUMP.

Buddy don't every blink and eye and washing out, if I every have hot mud with 2 % and hot water, I want wait more than 20 min max, in the summer time if I got a hopper full, 30 min max my way of washing out is fast than most I feed my hopper with a 1 1/4 inch water line from my supply tank ,from start clean out and reprime maybe 10 mins we even roll the excess sand out of the hose. Everybody know what a boom party feels like when theres no help.

I wil not act as a hero, but in my 6 years of pumping I have only two times have dumped my hopper. but that's the benefit that all the plant over here are using  GGBFS that give's you 2 a 3 hours before the concrete becomes hot.

Does that mean slower set times for the finishers?

2 1/2 hour wait for a fresh load, yeah, I think that the finishers would have a bit of time on their hands for the mud to start to go off.

Around here those pot smoking finishers would be climbing trees or sleeping waiting for there mud to set.

I was runnig a 39x for the company I have worked for over twenty years. I have had to wash out on them a few times in the past. The problem was with the batch plant breaking down so they say. Just one of those days. I am the bad guy becuase the forman said I held up his pour. I had the boom sucked back hopper dumped and reprimed with a bag of portland in about fifteen minutes. Like I say just one of those days.

Its like a double edged sword. Your damned if you do and damned if you dont. If they would be on top of the situation and stop making calls on there blackberry then worrying about the situation at hand like weres the fucking mud and the fact that the mud not being there is forcing you to save the pump so you can complete the job and the fact the mud not being thereis causeing the contractor to have a cold joint is important. Ask himthis would he rather you not finish the pour??????? Had to do it a couple of times myself and you can only resuculate forso long so fuck them and you save the day and your my fucking hero,hahahaha. So dust your shoulders off and pump another day. Oh thats right you will cause you save the pump. GOOD JOB BRO, pump on.

finishers?????? I havent seen them in months.

i look at it this way on a summer day im waiting 45 minz waitin any longer truck on the way or not im washing down cuz u dnt wanna beat no line but ur not the bad guy ur doin the right thing any how man so dnt let them tell ya diff
