Mixing concrete from scratch involves the combination of portland cement, sand, coarse aggregate (crushed and graded stone), and water. The industry standard uses a 1-2-3 formula with one part portland cement, two parts sand, and three parts aggregate for a 4,500-psi mix.

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 hardened. The strength concrete is inversely proportional to the water/cement ratio.
