How much water? How to tell?
I don't think I'm adding the right amount of water. I think I'm making it too dry or too wet. There's got to be another way to tell besides doing a slump test every time. I don't even know if the slump test will work for hypertufa anyway.
How do you tell? I read the FAQ but it's not info for me. Squeezing with some water coming out isn't telling me enough. I'm very inexperienced with concrete.
So, how do you tell?
