When making your own concrete it's important to use the correct concrete mixing ratios to produce a strong, durable concrete mixture. Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need.

What water:cement:sand ratio gives the strongest mortar?
You're talking about concrete, not mortar. Mortar is used to stick things together, not stand alone. A ratio by weight of 0.5 water, 1 cement, 3 sand, and 3 gravel should make a fine concrete, although a little less water (0.4 by weight) would make stronger concrete. The same by volume ( ie. buckets) is a good ratio as well, 1/2 to 1 to 3 to 3 ...
