The mixing time or period should be measured from time all the cementing materials and aggregates are in mixer drum till taking out the concrete Mixing time depends on the type and size of mixer, on the speed of rotation, and on the quality of blending of ingredients during charging of the mixer
Process of Manufacture of Concrete It is interesting to note that the ingredients of good concrete and bad concrete are the same If meticulous care is not exercised, and good rules are not observed, the resultant concrete is going to be of bad quality With the same material if intense care is taken to exercise control at every stage, it will result in good concrete
