Microsilica applications: Self-compacting concrete
Self-compacting concrete (SCC) can be characterised as flowing concrete without segregation and bleeding, capable of filling spaces and dense reinforcement or inaccessible voids without hindrance or blockage – without compaction.
SCC technology can eliminate or dramatically reduce the need for vibration, making it possible to reduce labour costs while improving the overall working environment for construction personnel. Faster placement and less finishing time can improve productivity and profitability. Increased flowability and consolidation can improve appearance and enhance the durability of the finished element. SCC will lower the overall cost of concrete construction.
The rheological properties of self-compacting concrete are greatly influenced by the amount and composition of the fine particles in the system. Elkem Microsilica, due to its extreme fineness and reactivity, will enhance SCC properties, and should be considered a beneficial and often necessary component of high performance self-compacting concrete.
