Concrete admixtures in general play a crucial role in production quality of concrete and mortars. Today in the industrialized countries up to 70 % of cement is used for ready-mix concrete.
Construction Industries demand grows each day, so admixtures importance increases exponentially. Admixtures reduce the surface tension between water and cement particles, correspondingly the release of entrapped water leads to high strength concrete and self-compacting concrete
Limitations of conventional admixtures:
Difficult placement in highly congested reinforced sections
Higher dosages needed at very low water retardation
