Self-compacting concrete (SCC), which flows under its own weight without being compacted or vibrating, requires no outside mechanical force to move. But like normal concrete, SCC has a brittle character (weak in tension) that causes sudden collapse with no advance notification. The tensile capacity of SCC has increased owing to the addition of steel fiber (SF). …
After a brief presentation of the two tools, the paper will highlight their application in the design of Self Compacting Concrete (SCC). The paper concludes by summarizing three full-scale ...
As a result, self – compacting concrete has been used in many practical structures. The first application of self – compacting concrete was in a building in June 1990. Self – compacting concrete was then used in the towers of a pre stressed concrete cable – stayed bridge in 1992. Since then, the use of self compacting

In this study, steel fiber-reinforced self-compacting concrete (SFRSCC) samples were examined by considering the effects of different proportions of steel fibers on the material presentation and to assistance the use of fiber materials in building construction...
Self compacting concrete SCC is a very fluid concrete and a homogeneous mixture that solves most of the problems related to ordinary concrete. Self Compacting Concrete gets dense and compacted due to its own self weight. An experimental investigation has been carried out to determine different characters like filling ability, passing ability ...

1. Self-compacting concrete is a fluid mixture suitable for placing in structures with congested reinforcement without vibration. The SCC can be made by three methods namely powder type,VMA type and combined type. VMA type is used in our project and Cement is replaced by fly ash at 20% by weight of cement. The basic material properties are studied and tabulated The …
Development of Self-Compacting Concrete For several years beginning in 1983, the problem of the durability of concrete structures was a major topic of interest in Japan. The creation of durable concrete structures requires adequate compaction by skilled workers. However, the gradual reduction in the number of skilled workers in Japan's construction industry has led to a …

Self compacting concrete is not affected by the skills of workers, the shape and amount of reinforcing bars or the arrangement of a structure and, due to its high ...
Self-compacting concrete (SCC) is a type of concrete, which flows under the sole influence of gravity up to leveling, air out and consolidates itself without any external compaction energy. It was a response to the lack of qualified skilled workers at the construction sites and a solution for the accomplishment of durable concrete structures.
This paper addresses experiments and theories on Self-Compacting Concrete. First, the features of "Japanese and Chinese Methods" are discussed, in which the packing of sand and gravel plays a major role. Here, the grading and packing of all solids in the concrete mix serves as a basis for the development of new concrete mixes.
