Essay / Self-Compacting Concrete - 1595
Self-compacting concrete (SCC), also known as self-compacting concrete, is a specialized high-performance concrete that does not need to be compacted by vibration as it compacts in all corners and all spaces. of a formwork under the effect of its own weight. The most laudable property of SCC is that it leaves no void in the formwork, without requiring mechanical vibrations (De Schutter, 2007; Okamura & Ouchi, 2003; Hurd, 2002). SCC therefore has superior technical properties which make it a very versatile and extremely useful material for construction. It was first developed in Japan in 1988 following research into the durability of concrete structures. Since then, research on SCC has advanced significantly, leading to its increased applicability in the construction industry. Evolution of self-compacting concrete – from necessity to invention “Necessity is the mother of invention,” says the adage. This is the story of Self-Compacting Concrete, the invention of which was born out of an urgent need. Increasing the durability of concrete structures was the major concern in Japan in the 1980s (Okamura & Ouchi, 2003). Japan faced a severe shortage of skilled workers in its construction sector, and concrete compaction had to be carried out by skilled workers to ensure the durability of concrete structures. Therefore, the development of a self-compacting concrete capable of filling each space of the formwork thanks to its own weight without requiring mechanical vibrations seemed a very promising alternative. This would also eliminate noise sensitivity, white finger syndrome and other environmental and biological disadvantages resulting from on-site vibrations (De Schutter, 2007). The concept of SCC was first created...... middle of article ......07). Report 38: Durability of self-compacting concrete - State of the art report from the RILEM technical committee.
