Topic > Self-compacting concrete - 1595

Self-compacting concrete (SCC), also known as self-consolidating concrete, is a specialized high-performance concrete that does not need to be compacted by vibration as it compacts into every corner and space of a formwork due of its own weight. The most laudable property of SCC is that it leaves no voids in the formwork, and that too without the need for mechanical vibration (De Schutter, 2007; Okamura & Ouchi, 2003; Hurd, 2002). SCC, therefore, has superior engineering properties that make it a highly versatile and immensely useful material for construction. It was first developed in Japan in 1988 as a result of research into the durability of concrete structures. Since then, research on SCC has made significant progress, leading to its greater applicability in the construction industry. Evolution of self-compacting concrete: from necessity to invention "Necessity is the mother of invention", goes the proverb. This is the story of self-compacting concrete, whose invention was born from an urgent need. Increasing the durability of concrete structures was Japan's main concern in the 1980s (Okamura & Ouchi, 2003). Japan was facing a severe shortage of skilled workers in the construction industry, and concrete compaction had to be performed by skilled workers to ensure the durability of concrete structures. Therefore, the development of a self-compacting concrete capable of filling every space in the formwork by virtue of its own weight without the need for mechanical vibrations seemed like a very promising alternative. This would also eliminate noise sensitivity, white finger syndrome and other environmental and biological inconveniences resulting from on-site vibrations (De Schutter, 2007). The concept of SCC was first formulated......halfway through the article......07). Report 38: Durability of Self-compacting Concrete - Report on the state of the art of the RILEM Technical Committee.
