The mix design procedure for self-compacting concrete is Example: A SCC mix powder content of 550 kg/m3 is taken by different as steps adopted for normal concrete mix and it is fixing 0.36 water/binder ratio by weight with 35% coarse based in Indian standard 10262-2008, but self-compacting aggregate content of concrete volume.
This paper proposes a new mix design method for self-compacting concrete (SCC). First, the amount of aggregates required is determined, and the paste of binders is then filled into the voids of aggregates to ensure that the concrete thus obtained has flowability, self-compacting ability and other desired SCC properties.
Self-Consolidating Concrete (SCC), also referred to as self-compacting concrete, is able to flow and consolidate on its own. At the same time it is cohesive enough to fill spaces of ... Submission of a performance based mix design which identifies all of the structural and ...

The mix design and testing methods are different compared with ordinary concrete.wide spread applications of Self Compacting Concrete have been restricted due to But lack of standard mix design procedure. However getting high strength self compacting concrete is simple compared to medium and low strengths.

The paper presents an experimental procedure for the design of self-compacting concrete mixes. The test results for acceptance characteristics of self-compacting concrete such as slump flow; J-ring, V-funnel and L-Box are presented. Further, compressive strength at the ages of 7, 28, and 90 days was also determined and results are included here.
Mix Design . SCC looks very different from conventional concrete while mixing. Concrete producers must "retrain their eyes" for this very fluid mixture as it turns corners and fills forms. Traditionally, concrete with the fluidity of SCC has had a very high water-to-cement ratio, which would lower compressive strengths and compromise ...
