• ### Concrete Mix Ratios - Cement, Sand, Aggregate .

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.
