Up to now there is no agreement about the mix design of the SCC. Many proposed method and tests have been introduced. Some of these methods start from bottom to top : cement grout (optimising the SP saturation point) then used this grout as a base to optimise the mortar,then the full concrete. This approach should consider the achieving of a maximum packing density of all the ingredients (coarse and fine aggregates, fine materials including cement and other used filler). Some of the proposed method start from top to bottom taking into account both the experience and all the limitations of SCC mix design such as cement past volume, sand to coarse aggregate ratio, volume of fine aggregate to volume of mortar ..etc. These ratios are very important to achieve the main requirements of SCC in fresh stage such as high filling and passing abilities and low segregation tendency .You can find more about these ratios in the original Japanese method (volumetric bases method). However, according to the citation of the attached paper, it seems that the proposed simple mix design procedure is mostly used.

Hi Mahi,
I think that one of the most used is the Baron and Lesage method.
