RELATION BETWEEN MIXING TIME AND CONCRETE MIXER TYPE

Concrete: Batching and Mixing | Concrete Technology

Mixing Time of Concrete: On a site it is often a tendency to mix concrete as rapidly as possible, therefore it is important to know the minimum mixing time necessary to produce a concrete of uniform consistency and composition to give satisfactory strength. Actually the time of mixing of concrete varies with the size and type of mixer.
