Self consolidating concrete test set

The successful development of SCC must ensure a good balance between deformability and stability.

Passing ability is one of the most important workability properties of self-consolidating concrete (SCC) and self-consolidating fiber reinforced concrete (SCFRC).

During his research, Okamura found that the main cause of the poor durability performances of Japanese concrete in structures was the inadequate consolidation of the concrete in the casting operations.

A simple, accurate, and practical passing ability tester (PAT) is proposed as a substitute to the conventionally used methods (J-ring, L-box, and U-box).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.Research studies in Japan are also promoting new types of applications with SCC, such as in lattice type structures, casting without pump, and tunnel linings.Self-compacting concrete development must ensure a good balance between deformability and stability.

Also, compactibility is affected by the characteristics of materials and the mix proportions; it becomes necessary to evolve a procedure for mix design of SCC.

Self-consolidating concrete (SCC) or self-compacting concrete, as it’s sometimes known, arrived as a revolution in the field of concrete technology.
