What factors affect the mixing time? - The American Concrete

With a proper loading sequence, truck mixers should adequately mix the concrete in 70 to 100 revolutions. If high-range water-reducing admixtures are added to the batch at the job site to produce flowing or high-slump concrete, an additional 30 revolutions of mixing should be used to provide adequate incorporation of the admixture.
