The basic assumption made in mix design is that the compressive strength of workable concretes, by and large, governed by the water/cement ratio. Another most convenient relationship applicable to normal concrete is that for a given type, shape, size and grading of aggregates, the amount of water determines its workability.
We have had numerous requests for concrete mix ratios by weight, by volume, and by mass. Here is a table that was released by the Cement and Concrete Institute for trial concrete mixes from 10MPa to 40MPa. These are trial mixes and should be used to test your concrete before it is used in any construction work. Your “competent person” or ...

The Buoyancy method uses the principle of displacement of water by different basic materials which are separated from the fresh concrete. The test was standardized in Britain until 1983 (ref.6). The test method is based on an assumption that solid particles having size lesser than 0.150 mm are almost entirely those of cement.
