SELF-COMPACTING CONCRETE
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).

A STUDY ON SELF COMPACTING CONCRETE
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.
Lateral Formwork Pressure for Self-Compacting …
Self-Compacting concrete (SCC) is known for providing a convenient working envi-ronment, especially in heavily reinforced structural elements. It offers faster construction, in comparison with normal concrete, due to a higher casting rate and having no need for compaction, [1–4]. Casting fluid-like SCC increases the lateral pressure exerted ...

Abstract. Sixty eight case studies of applications of self-compacting concrete (SCC) have been analysed. These were published from 1993 to 2003, the period of increasingly widespread use of SCC in many countries. They were selected for analysis on the basis of including details of concrete formulations and properties.

Difference between Self Compacting and Normal Concrete
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.
