What Is Concrete 31 Different Types of Concrete
#27. Self-Compacting Concrete-The concrete mix when placed will compact with its own weight is regarded as self-compacting concrete. No vibration has to be provided for the same separately. This mix has higher workability. The slump value will be between 650 and 750. This concrete due to its higher workability can also be known as flowing concrete.

Self Consolidating High Performance Concrete SCC
SCC mixtures can be designed to provide the required hardened concrete properties for an application similar to regular concrete. If the SCC mixture is designed to have a higher paste content or fines compared to conventional concrete an increase in shrinkage may occur. SCC A high-performance concrete innovation.
