I want to create a stone looking structure for my yard. I was told to use molasses in the quickcrete to make it stronger, use a concrete tint or dye to get a better color, and to use a solvent based sealer so that it will last longer and survive the weather changes. I would like to have some verification of this information if anyone can help me out. The basic structure will be a column of sorts, but I want it to look like stone, not just plain concrete. I was thinking about using a wooden and wire frame and applying the concrete mix directly to it, shaping it as I add to it. If anyone knows more about this sort of thing or has a better idea/way of doing it, please let me know.
