I built an extension on my house in the UK some 20 years ago. Hard work shifting 4 cubic metres of cement when your partner does not turn
up!
Always chucked a few broken bricks in the hired mixer to clean it out. Now I am just thinking what the professional cement makers do with their ginormous trucks to clean out a 15 ton wagon. I am sure someone on here knows. I certainly do not. No broken bricks in their wagons!

1. Tell her to get out of bed  2. Lots of water and, more importantly, constant use. Perhaps being slightly helpful - Lots of washing up liquid? |

Normally, the drum is washed out to clean it.
In my past life I was part of a team that demonstrated a manufacturer's trucks to potential customers. One truck was cement mixer and during a demonstration it got bogged down in a field. Concrete mix goes off very quickly if the drum stops turning and by the time a suitable recovery truck was located it had gone solid. Hammer and chisel job to clean that drum. |

I have always poured water and a few handfuls of gravel into it as soon as my last mix has been tipped out, then let it run for a while. Not a few days/weeks/months later.

I used to use a pressure washer as soon as the mixing job was finished.

I have been in the yard when a driver who was very slow had his cement dry in the drum and it was his responsibility to climb in and jack hammer or hammer and chisel it out. A big chuck fell and snapped his leg... Took the ambulance service and firefighters ages to get him secure and out.

The only time I’ve been involved with a readymix delivery here in France part of the bill was for the time it took the driver to put the drum through a cleaning routine before leaving.

I kept our cement mixers immaculate during 18 months daily use, just using a hose and brush. The ready-mix lorries washed out their drums into the ditch at the side of our chemin. Not eco-friendly, but it did mean less fauchage for the Mairie  |

Thanks for the answers everyone. I just wonder how the larger concrete companies get rid of their cement mixed water. Surely not just in to the ground?

Many firms have land that they own which is just for that purpose.Some have concrete crushing machines which they use to turn the waste into hard core.
