Self-compacting concrete has the characteristics of resistance to segregation, easy filling, easy passage, high fluidity and high deformation ability, and can maintain homogeneity during and after transportation and pouring.
Self-compacting concrete (SCC) was developed in 1988 and introduced by Professor H. Okamura to achieve durability of structures with low skilled laborers. The three properties of SCC that differentiates it from traditional concrete are passing ability, filling ability and segregation resistance.

Filling and passing ability, segregation resistance are the properties of self compacting concrete. 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 explained in the below sections.
Self-compacting concrete (SCC) is a flowing concrete mixture that is able to consolidate under its own weight. The highly fluid nature of SCC makes it suitable for placing in difficult conditions and in sections with congested …
The document discusses light weight self-compacting concrete (LWSCC) using different lightweight aggregates (LWA). It finds that: 1) Increasing the percentage replacement of natural aggregates with LWA like perlite, scoria, and bottom ash slag (BST) decreases the mechanical strength and workability of LWSCC. 2) BST mixes had the …
Self-compacting concrete (SCC) was developed in Japan in the 1980s to solve issues with inadequate concrete compaction. SCC is highly flowable under its …
It covers the importance of compacting concrete to remove air voids and increase strength. Methods of compaction include manual techniques like rodding and tamping as well as mechanical vibration using internal and external vibrators. Improper vibration can lead to defects like honeycombing or segregation. Newer techniques like …
Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even …
SELF COMPACTING CONCRETE. ppt.pptx. - The study aimed to determine the bond strength and chloride permeability of self-compacting concrete (SCC) compared to conventional concrete (CC). - Materials were tested to determine properties and optimize an SCC mix with 20% fly ash replacement. Workability tests established …
This led to the development of self-compacting concrete, primarily through the work by Okamura 1. A committee was formed to study the properties of self-compacting concrete, including a fundamental investigation on the workability of concrete, which was carried out by Ozawa et al 2. at the University of Tokyo.
Self-compacting concrete (SCC), which flows under its own weight without being compacted or vibrating, requires no outside mechanical force to move. But like normal concrete, SCC has a brittle character (weak in tension) that causes sudden collapse with no advance notification. The tensile capacity of SCC has increased owing to the addition …
Self Compacting Concrete (SCC) is a specialized type of concrete that possesses unique flow and self-leveling properties, allowing it to fill and distribute evenly within formwork without the need for external …
Development of SCC In 1986, concrete capable of compaction by its own weight with no need of vibration was proposed In 1988, first successful prototype of self compacting …
Self-compacting concrete can be considered as the greatest technical development in concrete technology over the years, at least from 1980 till today. This is the concrete of the futures, as it will be replacing the normal concrete because of its many advantages.

Self-compacting concrete is a type of concrete that can flow and consolidate under its own weight, without the need for excessive vibration. It is made up of a carefully selected combination of materials such as cement, fine aggregates, water, and chemical admixtures that enhance its flowability and stability.
Self Compacting Concrete (SCC) is a type of concrete that is particularly designed to flow smoothly and uniformly into even the most complicated and crowded locations without the need for mechanical consolidation. This article goes into the realm of self-compacting concrete, examining its elements, advantages, uses, and effects on the environment.

Abstract. Self-compacting concrete (SCC) is design to achieve three functional requirements, which are filling ability, passing ability, and resistance to segregation. These requirements are necessary to properly fill the formwork and adequately encapsulate reinforcing bars only through the action of gravity, while maintaining good homogeneity.
Concrete containing dispersed randomly oriented fibres in SCC is known as Fibre reinforced self compacting concrete.
