A typical concrete mix cannot be made without gravel. Concrete is made from a mixture of cement, sand, gravel (crushed stone), and water. A mix ratio of 1 part cement, 2 parts sand, 3 parts gravel, and water, will give you a strong concrete mix. If you subtract the gravel from concrete, you have what's called a mortar mix.

A trial mix determines this mix ratio, where different proportions of cement, sand, and aggregate are tested to determine the optimal mix ratio. The design mix ratio is usually specified in terms of the proportions of cement, sand, aggregate, weight, and any required admixtures.
A cement ratio mix is what determines how strong or weak your concrete will be. It's the ratio of portland cement quantity to the aggregate of your concrete. The more portland cement you add, the stronger and sturdier your concrete will be. That means that a higher cement ratio will result in a harder product, but also a weaker one because ...

Using the coarse aggregate content table with the given nominal maximum aggregate size of 37.5 mm (1.5 inches) and the given fine aggregate fineness modulus of 2.80, the recommended volume fraction of coarse aggregate is 0.71. This means that the coarse aggregate should occupy 71 percent of the total volume. …
As shown in the table, both 3000 psi and 4000 psi concrete have the same mix ratios of 1 part cement to 3 parts sand and 3 parts aggregate. The difference lies in the increased amount of cement used in the 4000 psi mixture, resulting in a higher compressive strength.It's important to consult with a professional to determine the …

It will mix the water/cement ratio on the concrete, resulting in not-so-optimal strength. This is why I prefer the following method over this. Also, this technique must be used correctly (i.e., when the cement paste is still soft but the aggregate is solidified and will not get dislodged from the strain), so it can be challenging for beginners.
As a quick answer, a concrete mix ratio of 1 part cement, 2 parts fine aggregate (sand) and 4 parts course aggregate will cover most general domestic jobs.
