Right ratio for making bowls with concrete? Answered
I recently got someone to buy me concrete mix - I asked for ready mix as I've seen people suggesting Quikrete, but I ended up with 2 bags - one with the cement and one with the gravel and sand.
Now, I want to make smallish bowls for outdoor use over the weekend (bird baths, small plantholders, etc.), but I'm not sure what my ratio must be for the sand / cement or sand / cement and gravel mix (and I'm not planning on buying another product). I've read that people can mix only the sand and cement for a smooth finish, but will this be strong enough? The gravel I have is quite large, and it might make the finish too chunky when the concrete is dry.
I'm also planning on not using bowls or containers as molds - I want to smooth it out on the outside or inside of a bowl by hand with a trowel or something similar. Will I be able to make this work? I want to make small bowls, so I don't need to mix large amounts at once. I have never worked with concrete before, so I want to start out with small items anyway just to get the hang of things.
