Literature on the quality of water for mixing and curing concrete indicates that relatively few investigations on this subject have been conducted. It seems to have been generally agreed that water fit to drink was fit to use in concrete mixing, and even fewer limitations were applicable to curing-water quality. Tests were conducted by the Missouri

How to Properly Mix Concrete (DIY) | Family Handyman

Whether you hand mix concrete in a plastic tub, homemade mixing tub or wheelbarrow, the technique is the same to find the right concrete mix ratio. However, it's easier to move and dump concrete that's mixed in a wheelbarrow. For larger jobs, you could rent a mixer ($35 per day), but it may be more economical to simply order ready-mix concrete.
