Get PriceMix design of HPC is complicated by the fact aggregate strength or the strength of the cement-aggregate bond, are often the strength controlling factors and the role of water-cement ratio is less clear. The water-cement ratio is a poor predictor of compressive strength in high strength concrete 9.

Get PriceA low water to cement ratio is the number one issue effecting concrete quality.. The ratio is calculated by dividing the water in one cubic yard of the mix ( in pounds) by the cement in the in the mix (in pounds). So if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement- the mix is a .50 water to cement ratio.
