Self-compacting concrete (SCC) is a key innovation in concrete technology and it is truly remarkable that, even after almost 30 years since its first implementation, it still attracts the interest ...
Abstract. Self-compacting concrete (SCC) has many benefits in terms of production and placement compared to traditional concrete namely, elimination of external or internal vibration for compaction, better flowability, workability and pumpability, as well as increased bonding with congested reinforcement.
Based on Eurostat – European Statistical Office, European Union is the source of around 895 400 t of waste per year (waste from mining not included) [24].About a third comes from the civil engineering sector [25] and so having a huge influence on the final score. Wastes from mineral excavation in Poland in 2022 are forecast at 64 300 …
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.

Self-compacting concrete (SCC) is a highly engineered concrete that addresses these requirements. It was developed around 1988 in Japan, to improve the durability of concrete structures.
5. INTRODUCTION Concrete that requires little vibration or compaction has been used in Europe since the early 1970s but self- compacting concrete was not developed until the late 1980's in Japan. In Europe it was probably first used in civil works for transportation networks in Sweden in the midl990's. The multi-national, industry lead …
Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. The hardened concrete is dense, homogeneous and has the same engineering ...
Self Compacting Concrete (SCC) is a type of concrete that is particularly designed to flow smoothly and uniformly into even the most complicated and crowded locations without the need for mechanical consolidation. This article goes into the realm of self-compacting concrete, examining its elements, advantages, uses, and effects on the environment.
21. CONCLUSION Self Compacting Concrete (SCC) technology can save time, cost, enhance quality, durability and Moreover it is a green concept. Since the concrete is capable of self-consolidating and reaching the difficult areas in moulds, manual variables in terms of placing and compacting concrete is nil. This factor ultimately …
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 …
Self-compacting concrete (SCC) was developed in 1988 and introduced by Professor H. Okamura to achieve durability of structures with low skilled laborers. The three properties of SCC that differentiates it from traditional concrete are passing ability, filling ability and segregation resistance. The present study highlights the developments ...
2. Self-compacting concrete (SCC) is considered as a concrete which can be placed and compacted under its own-weight with no vibration . It is not affected by the skills of workers, the shape and amount of reinforcing bars or the arrangement of a structure. Due to its high-fluidity and resistance to segregation it can be pumped longer …
Filling and passing ability, segregation resistance are the properties of self compacting concrete. SCC possess superior flow ability in its fresh state that performs self …
Self compacting concrete (SCC) adalah sebuah beton yang inovatif yang tidak memerlukan penggetaran saat penuangan dan pemadatan. SCC mampu mengalir dibawah pengaruh berat sendirinya (hanya dengan mengandalkan gravitasi), mengisi formwork secara menyeluruh dan mencapai pemadatan penuh, bahkan dalam keadaan …
Self compacting concrete (SCC) can be defined as fresh concrete that flows under its own weight and does not require external vibration to undergo compaction. It is used in the construction where it is hard to use …

Factors Affecting Performance of Self compacting concrete . Using self-compacting concrete must not be used indiscriminately. These factors can affect the behavior and performance of self-compacting concrete: An increase in the working temperature highly decreases the flowability and fluidity of the SCC as it causes the mix to dry off quickly.
