What happens if you add too much water to concrete?

When mixing concrete the ratio needs to be perfect. Too much water added will make the overall strength weaker, and cause shrinkage or cracking. If too little water goes into the mix then it will set dry, crumbling and breaking apart. It is one of the most critical parts of mixing, that just the right amount of water is added.
