In Japan, the volume of SCC in construction has risen steadily over the years.Data indicate that the share of application of SCC in precast concrete industry is more than three times higher than that in the ready-mixed concrete industry. The estimated average price of SCC supplied by the RMC industry in Japan was 1.5 times that of the conventional concrete in the year 2002.
Incorporation of aggregate shape in mixture design, based on the method developed by O’Flannery and O’Mahony, is explained in Table 1.Current Developments in Self-Compacting Concrete Introduction Self-compacting concrete (SCC) is a flowing concrete mixture that is able to consolidate under its own weight.The highly fluid nature of SCC makes it suitable for placing in difficult conditions and in sections with congested reinforcement.Moreover, SCC almost always includes a mineral admixture, to enhance the deformability and stability of concrete.Issues linked with the use of chemical admixtures are discussed in this section.
Another deficiency in aggregates is poor gradation.
