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 (or a little less water- too much water weakens the concrete, and there will always be some water ...

The basic mix ratio for concrete is one part water, two parts cement and three parts sand. An alternative ratio is one part cement, two parts sand and three parts gravel with enough water added until the mixtures reaches the consistency of thick mud.
Rarely, it is appropriate to add cement mix over a gravel driveway. Many cement driveways use pea gravel under the cement to prevent the cement from cracking and breaking when the ground shifts. However, most gravel used for this purpose is specifically designed to be used under cement.
Without aggregate, you're basically going to have grey plaster with little inherent strength for both tension and compression. Even small aggregate, sand and pea gravel, will make a significant difference in the strength. Aggregate to cement proportions should be about 3 parts aggregate to 1 part cement by volume for field/hand mixed concrete.
