I'm a newbie to pouring larger quantities of concrete/mortar/cement. I have a batch I'll need to mix of 3 100 lb bags white portland cement and 5 100 lb bags of tiny pebbles. What is the smallest size mixer I can rent that will do this batch all at once? The local rental has 6 cu ft and 9 cu ft tow-behind mixers. How much water should I add initially? I am afraid of accidentally adding too much water or if I'm too cautious and add it too slowly maybe it would take away a bit from my troweling working time. How long to leave it spinning round the mixer?
