Generally in past, the concrete specifications had recommended the proportions of cement, coarse and fine aggregates. These constant cement-aggregate ratio mix that gives the sufficient strength are marked as the nominal mixes.
An excessively wet mix is a contributing factor to shrinkage in concrete. While water is an essential ingredient in every concrete mix, there is such a thing as too much water. When the mix contains too much water, the slab will shrink more than if the correct amount of water was used. Hot weather is another big reason for plastic shrinkage cracks.
A concrete mixer (often colloquially called a cement mixer) is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete.A typical concrete mixer uses a revolving drum to mix the components.

Concrete mix ratio is a vital topic in concrete mix design. The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed.
Concrete mixing ratios are the formula for calculating the correct amount of each ingredient used, including water, cement, sand and aggregate, to produce concrete with the properties desired. A basic concrete ratio is one part cement, two parts sand, and three parts gravel, slowly mixing in water until workable.
