Testing and mix design method of self-compacting concrete hardik upadhyay1, pankaj shah2 abstract— self compacting concrete is a highly flowable, yet stable concrete that can spread readily into place and fill the formwork without any consolidation and without undergoing any significant separation in general, scc results in reduced. Self-compacting concrete (scc) self-compacting concrete (scc) is a flowing concrete that does not require vibration and, indeed, should not be vibrated it uses superplasticisers and stabilisers to significantly increase the ease and rate of flow it achieves compaction into every part of the mould or formwork simply by means of its. Self-consolidating concrete construction construction is where scc really shines what could be better than a mix that consolidates itself, eliminating all vibration, lift lines, and bugholes for flatwork, scc mixes can be described as self-leveling while formed concrete can be self-placing here are a few tips on construction with scc: scc can.
