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.

2. Self-compacting concrete (SCC) is considered as a concrete which can be placed and compacted under its own-weight with no vibration . It is not affected by the skills of workers, the shape and amount of reinforcing bars or the arrangement of a structure. Due to its high-fluidity and resistance to segregation it can be pumped longer …

Introduction. Definition: Filling of the cracks is a biological reaction or in other words, a product i.e, limestone is produced within the concrete with the help of bacteria and after hardening it fills the crack known as self healing of concrete, It is also known as bacterial concrete. The bacteria which is present inside the concrete will be in a dormant …

As a result, self – compacting concrete has been used in many practical structures. The first application of self – compacting concrete was in a building in June 1990. Self – compacting concrete was then used in the towers of a pre stressed concrete cable – stayed bridge in 1992. Since then, the use of self compacting
