For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate. The proportions are either by volume or by mass. The …[...]

Sep 25, 2017· Fourtwoone and the Seven Part Mix Ratio. The safest bet for any concrete mix is fourtwoone: four parts crushed rock; two parts sand; and one part cement. The fourtwoone mix, obviously, has seven parts. Conveniently, when mixing concrete, the ratio can be mixed on any range of scales.[...]

Concrete Trial Mix 2: To increase the workability from 25 mm to 5075 mm an increase in water content by +3% is to be made. The corrected water content = 191.6 x 1.03 = 197.4 kg. As mentioned earlier to adjust fresh concrete properties the water cement ratio will not be changed. Hence. Cement Content = (197.4/0.5) = 394.8 kg/m 3[...]
