### Mix design of high-performance concrete - SciELO

The water-cement ratio is a poor predictor of compressive strength in high strength concrete 9. There are methods of mix design of HPC such as method proposed by Aitcin 1, Mehta and Aitcin 2, Indian Standards mix design method 10 among other methods. Most commonly, purely empirical procedures based on trial mixes are used.

### Calculate cement sand and aggregate | Nominal Mix Concrete ...

NOMINAL MIX CONCRETE DESIGN FOR ONE CUBIC METER OF M20 CONCRETE BY VOLUME. Because, in the begining, cement and sand has to fill the gaps between the aggregate (crushed stone). At the same time, if 40mm aggregate is used, total materials needed will be 1.52 cubic meter. Let''s calculate material required for M20 grade to prepare one cubic meter concrete.
