Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi.. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets strength concrete is inversely proportional to the water/cement ratio.

The concrete consistency method normally requires the establishment of specific mixture parameters such as the amount of aggregates, the amount of water, or the amount of cementitious materials. One of these parameters is then adjusted in order to meet a required level of consistency, often measured using an apparatus called a Vebe consistometer.
