If I make 4 of these statues, 1.25x life-size, then how much concrete should I purchase?
The plan is to make a mould and pour into that.
The original Ludovisi Ares is 1.56 m in height. Therefore: (x1.25) 1.95 m high.
Update: I need to know how much Portland Cement (White), how much sand, and how much aggregate to order, and need a suggested recipe for the proportions of each and size(s) of aggregate I should use.
It has to be liquid enough to pour into a mould and take the shape, but strong enough after drying to stand in public and withstand subtropical temperates and humidity, heavy rain, strong winds, and cold temperates (rarely freezing, 0℃ only one day a year if even that).
Finally, I will cure it for a full 28 or 30 days, and want it to have as smooth a finish ad possible.
Any and all advice would be appreciated. Thanks.
