Abstract. Self compacting concrete (SCC) is a type of concrete which can flow and spread through reinforcement and narrow sections which fills the empty spaces completely without any mechanical vibration. This type of concrete requires large quantity of powder, for which either fine pozzolanic (e.g. fly ash, ground granulated blast furnace slag and silica fume etc) or non-pozzolanic additions (crushed …

May 10, 2016 self-compacting concrete (scc) is an innovative concrete characterized by its ability to flow under its own weight without segregation or blocking and to achieve full compaction without vibration (gesoğlu et al., 2012, naik and vyawahare, 2013). thus, scc can be cast without honeycombing where it is difficult to mechanically compact fresh concrete, such as underwater concreting…

Due to its high fineness and physical and chemical properties, the marble and granite sawing waste (mgsw) is an excellent filler to self-compacting concrete. its employment avoids the use of limestone filler, commonly used in this type of concrete. this reduces the use of raw materials and energy in the self-compacting concrete production.

Self-compacting concrete test are slightly different from the tests that are conduction on normal concrete. there are three basic characteristics of self-compacting concrete namely filling ability (flowability), passing ability (free from blocking due to the presence of reinforcement), and resistance to segregation (stability/homogeneity). therefore, it is very necessary to carry out field or mock trials to …

It increases the strength of concrete. self compactibility = high deformability + high segregation-resistance. self-compacting concrete can also be defined as a mix balancing the fluidity and resistance to segregation where those two properties are conflicting with each other. a balanced equilibrium should be maintained between them.
