Self Consolidating or Self Compacting Concrete (SCC) is a highly flowable, deformable, non-segregating concrete that spreads and fills in the formwork under its own weight. Flowability is maintained by using a high range of water-reducing admixtures. Stability (avoiding segregation) is increased by using admixtures or increasing the number of ...

concrete is dense, homogeneous and has at least engineering properties at par with and durability as traditional vibrated concrete. The principle behind Self Compacting Concrete (SCC) is that the settlement of aggregates is related to the viscosity of the fresh concrete. SCC can be produced using the same ingredients as that of normal concrete.

Self-compacting concrete (SCC) has been report as "the nearly all revolutionary extension in concrete construction for many decades". initially developed in Japan, SCC technology was construct doable by the a lot of earlier development of Superplasticiser for concrete. SCC has currently been preoccupied with keenness

SCC possess superior flow ability in its fresh state that performs self compaction and material consolidation without segregation issues. The materials, tests and properties of self compacting concrete are …

1. Concrete has high flowability to undergo compaction by its own weight. Concrete is compacted by external means of vibration. 2. High workability. Less workable mix. 3. Workability gained through superplasticizers and viscosity modifying agents. Workability gained through increased moisture content.

Self compacting concrete mix design tool is developed based on the key proportions of the constituents. This tool is very simple and user friendly for the self compacting concrete mix design. It can be used for the SCC mix with or without blended cement and coarse aggregate with or without coarse aggregate blending.

of self-compacting concrete, the fineness modulus of sand should be more than 2. 5. 2.1.2 Active admixture Mixing mineral admixture in self-compacting concrete can meet the workability requirements and reduce the cement consumption. At present, the ash is most commonly used. The micro aggregate effect, active effect and morphological effect of

Self-compacting concrete was therefore developed to overcome the problems mentioned above. Self compacting concrete is defined as a concrete which is capable of self consolidating without any external efforts like vibration, floating, poking etc. The mix is therefore required to have ability of passing, ability of filling and ability of being ...

The backbone, which includes ionic carboxylic or sulfonic groups, adsorbs onto a cement particle and the nonionic side chains extend outward from the cement particle. The side chains physically separate cement particles, which is referred to as steric hindrance as illustrated in Figure 2.19 (Koehler et al., 2007).

Self – compacting concrete (SCC) is a high – performance concrete that can flow under its own weight to completely fill the form work and self consolidates without any mechanical vibration. Such concrete an accelerate the placement, reduce the labor requirements needed for consolidation, finishing and eliminate

IRJET Journal. A self compacting concrete (SCC) is a flowing concrete mixture that is able to consolidate under its own weight. In certain instances the addition of super plasticizers and viscosity modifier are added to the mix, reducing bleeding and segregation. Silica sand is a byproduct obtained from cement manufacturing process.

The self-compacted concrete mixtures were designed according to the rational mix design by [23].A total of five SCC mixes were designed with water binder ratio (w/b) ratio of 0.45 and a total binder content of 450 kg/m 3.The control mix was made only by Ordinary Portland cement as a binder material.
