Influence of mixing protocol on fresh and hardened

Yield stress and viscosity are the two important parameters to be considered in the production of self compacting concrete. Concrete will have low workability if the yield stress or viscosity is too high. To produce a mix with low yield stress which is preferred for SCC, mixing process should be at higher shear rates.

Concrete Mix Ratios - Cement, Sand, Aggregate and Water

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.
