Concretes without admixtures and of high cement content, (over about 460 kg/m 3) are liable to prove difficult to pump, because of high friction between the concrete and the pipeline.Cement contents below 270 to 320 kg/m 3 depending upon the proportion of the aggregate may also prove difficult to pump because of segregation within the pipe line.
It has a high effect on the strength and workability of concrete. So, in this article, we'll briefly discuss the calculation, maximum and minimum value of the water-cement ratio for M10, M15, M20, and M25, etc. In the concrete Mix design, the ratio between water to the amount of cement (by weight) is known as a water-cement ratio.
