Self Compacting Concrete (SCC) is a concrete that is capable to compact under its own load.

Also in past, making Concrete structures without compaction and vibration have been done. For examples, placing of concrete under water is done without vibration. Mass concrete and shaft concrete can be well placed without compaction.
But the examples of these concretes are generally of lower strength and it is difficult to obtain uniform quality.

Recognizing the need of uniformity and complete compaction of concrete, the Scientists at University of Tokyo, Japan; started to develop Self Compacting Concrete. By the early 1990's Japan has developed and adopted Self Compacting Concrete that doesn't require vibration to attain full compaction.

Self Compacting Concrete has been described as 'The most Revolutionary development in concrete construction for several decades.'

Advantages:

Originally developed in Japan to offset a growing shortage of skilled labour, it has provided to be beneficial from following points:

• Faster Construction.

• Reduction in site manpower.

• Better surface finish.

• Easier Placing.

• Improved durability.

• Greater freedom in design.

• Thinner Concrete sections.

• Reduced Noise Level.

• Safer working Situation.     

5. Mineral Admixtures: Fly ash, Blast furnace slag, Stone Powder, Silica Fumes, Fibres may be used to improve the properties of Self Compacting Concrete.

Self Compacting Concrete Mixes:

There are three ways in which Self Compacting Concrete can be made:

1. Powder Type

1. VMA Type

1. Combined Type.
