ABSTRACT

There have been several design methodologies based on the different perceptions of the individual research efforts but all of them looked at mostly the primary requirement of self-compactability. This chapter attempts to look deeper into the different methodologies proposed by various researchers, to categorize them based on the major thrust in their design philosophy, and also go through some of their designs in specific to get a comprehensive picture of the resulting self-compacting concrete composites. Briefly these can be classified under empirical methods, matrix fluidity based designs, packing density approaches, and some that also look at the resulting strength characteristics appropriately. The resulting compositions through some of these methodologies for the range of concretes they propose were all calculated and the results have been presented graphically to comprehensively understand and compare the same. It is obvious that there is a wide variation possible from these different designs depending upon the major thrust in their approach. Based on these observations it was seen that there is need for a relook into the design of self-consolidating compositions. A broad set of guidelines to arrive at such a methodology is also presented.
