The sixth National Conference on Self-Consolidating Concrete

Self-compacting concrete compacts under its own weight without mechanical vibration and fills all voids in the formwork or between the bars without creating air bubbles. Some of the main advantages of using self-compacting concrete in the construction of structures include the ability to flow through the compacted bars and into forms with complex shapes, increasing the speed of construction of concrete structures, improving the quality of construction by ensuring adequate compaction in areas with high rebar density, and improving the durability of concrete as a result of better compaction of fresh concrete. The use of self-compacting concrete is recommended in concreting in areas with high rebar density. The three main characteristics of these concretes include flowability, ability to pass through the rebar network, and consistency (stability). Due to the three properties mentioned, self-compacting concrete is distinguished from ordinary concrete. In other words, it is not possible to examine the capability of self-compacting concretes by just performing a simple slump test, but rather, multiple tests are required, such as: slump flow and time 50 cm (T50), visual stability index (VSI), J-ring test, L-box test, and V-funnel test.
