Abstract:
Self-consolidating concrete (SCC) is a highly flowable, yet stable concrete that can spread readily into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation and without undergoing any significant separation of material constituents. SCC has many advantages over conventional concrete, such as: eliminating the need for vibration; decreasing the construction time and labor cost; reducing noise pollution; improving the filling capacity of highly congested structural members; improving the interfacial transitional zone between cement paste and aggregate or reinforcement; decreasing the permeability and improving durability of concrete; and facilitating constructibility and ensuring good structural performance. SCC has been attracting more and more attention worldwide since its introduction in the late 1980s. New applications for SCC are being explored.
