Can someone advise me on why cement would ball up like this in a mixer and how to avoid it?
If you can gauge the total amount of water and put it in at the beginning then you will fare better. Otherwise just add water BEFORE adding more material into the drum. If you intend leaving the muck in the drum for a long period, then leave it wet. Add more gear prior to tipping it out if you need to.I'll try starting with more water today and see how I get on.
What with your wobbly patio slabs I'm suspicious of your cement.
I've just been to check the cement bags for a date but can't see anything - what would you consider to be old?
It aint the cement bud. Concrete sand is notorious for allowing the balling up of the cement when mixed in the wrong sequence. Amateurs who have attempted floor screeding (dryish mix) are testament to that.I've just been to check the cement bags for a date but can't see anything - what would you consider to be old?
