Hi folks,

I'm trying to work out the weight/volume of ingredients I'd need for a given volume of concrete. I presume the volume of concrete you end up with is not the combined volume of the ingredients?

Edit:

I know the volume of the casts...

Do I just assume a certain density for the finished concrete and thus calculate the finished weight and then assume that the combined weight of the ingredients should equal this weight?
