Posted By Homer Came across an interesting one today where I had to stop a job.
Periodically, I am now lead to believe, we have to clean the internals of our mobile mixer using a breaker to stop cement build up.
I saw it first hand today, the operator climbs inside the mixer unit and using an electrically powered breaker powered from a 110v generator basically chips away residual cement. I was not impressed all work promptly stopped.
It was a confined space, there were noise issues, there were vibration issues, the generator had been placed in such a way as to allow fumes to enter the mixer, there was no watcher, there was no time break person to swap with, there was no control on the ignition key and to top all this he had no gloves, no mask no eye protection etc. etc. etc.
Many of the issues are easily resolved but how do we actually clean the inside without entering it, there's no vent port and flushing with air would only increase levels of dust.
Anyone out there come across similar problem but without the stupidity element, there must be a way of safely entering this without it becoming a confined space issue

Posted By Winsley Hose it out before the cement dries, if this is possible.

Posted By Steve Couch Homer, what size mixer are you talking about? and when you say mobile? I take it this is used in various places e.g. buiding sites?

Posted By Merv Newman I usually bash the outside of mine with a club hammer. Leads to an interesting dimpled effect.
But most builders I have seen chuck in a couple of buckets of water at the end of the day and let it swish around. Same goes for cement lorries which usually come equiped with a water tank and hose just for cleaning out after delivery.

Posted By Homer Maybe didn't make myself clear it's a lorry and occassionally irrespective of how much washing out it get you have to chip away the inside.

Posted By justgossip Would there be any mileage in loading sharp aggregate into the mixer, then allow this to be rotated to act as an abrasive cleaner....maybe

Posted By SJA Try talking to Hymix or one of the other manufacturers. I have never come across the need to do this before, and therefore suspect that there are probably standard cleaning/operational procedures which will prevent such build-ups from occurring. www.hymix.com

Posted By Chris Pope There is a new product on the market which softens it, but I can't remember the name. It is not a form of brick acid. I might have seen the ad in professional builder or somewhere

Posted By Steve.C Try Duzz, it can be obtained from http://www.inpetro.com , i believe it is sugar based and works by ion exchange and softens hard cement so it can be washed off. It also appears harmless and enviro friendly. Steve
