SCC is a kind of high fluidity concrete without vibration, also known as Self-Consolidating Concrete and High Performance Concrete, which was discovered by the University of Tokyo in Japan in the 1980s. SCC usually uses a large number of mineral admixtures and chemical admixtures to achieve a dense state without vibration under the action of its own gravity, and then fill the formwork with dense steel bars. SCC has the characteristics of resistance to segregation, easy filling, easy passage, high fluidity and high deformation ability, and can maintain homogeneity during and after transportatio...
SCC is a kind of high fluidity concrete without vibration, also known as Self-Consolidating Concrete and High Performance Concrete, which was discovered by the University of Tokyo in Japan in the 1980s. SCC usually uses a large number of mineral admixtures and chemical admixtures to achieve a dense state without vibration under the action of its own gravity, and then fill the formwork with dense steel bars. SCC has the characteristics of resistance to segregation, easy filling, easy passage, high fluidity and high deformation ability, and can maintain homogeneity during and after transportation and pouring. Due to fewer defects in microstructure, scc can meet the requirements of strength, volume stability and durability of concrete (Wu et al., 2015).Because of its high working performance, scc is most suitable for the pouring of mass concrete. In order to maintain the deformability and cohesion of concrete, it is usually used in scc with superplasticizer, a large amount of reactive powder and viscosity improver (Prakash et al., 2021). Due to the use of higher powder content in scc there are more small pores and less available water in concrete (Zhang et al., 2003).
