Estimating weight of oven: does water count?

[kebwi]

I know how much concrete, concrete block, rebar, brick, mortar, hardibacker (concrete board), and stucco went into each stage of construction (I forgot to note the number of bags of concrete for the hearth but I can approximately extrapolate it from the foundation which is geometrically similar). This means I can make a reasonable estimate of the weight of the entire structure.

But for a weight-estimate, I'm not sure if I'm supposed to count all the water that went into the concrete, mortar, and stucco. I understand that concrete doesn't "dry out", but rather that it "sets", but ultimately, what does that mean in terms of water retention or loss -- is the water actually retained forever, or does it work its way entirely out of the cement such that years later, the total weight is only that of the cement and not of the water that was mixed into it?

Thanks.

The water will eventually all evaporate from the concrete and mortar.

Not all of it, but enough not to worry about. I think the last one I built was about 300#s heavier than it should have been.

What is the weight of an average oven ?
I want my one to go on a balcony eventually.

Re: Estimating weight of oven: does water count?

I ran the numbers this weekend which is why I was asking about the water. Assuming water is virtually a nonissue, my oven weighs about 5.3 US tons including the foundation slab. I wanted to calculate its weight because I'm curious about the possibility of moving it if I ever move a reasonable distance (i.e., within town).
