I make that approx 0.25m^3 of concrete: how do I calculate how much agg
and cement is required for this?


There are 42 wickes bags of aggrigate to the tonne, and arround 2
tonnes to the cube. So you need 21 bags of aggrigate.

The easiest is to buy "ballast" which is sand/cement allready mixed.


4:1 ballast to cement is good
