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 as a result of its own weight. The most laudable property of SCC is that it leaves no void in the formwork, and that too, without the need of 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 on durability of concrete structures. Since then, research on SCC has progressed to a large extent, leading to its increased applicability in the construction industry.
Evolution of Self-Compacting Concrete – From Necessity to Invention
‘Necessity is the mother of invention’, goes the adage. Such is the story of Self-Compacting Concrete, whose invention materialized out of an urgent need. Increasing the durability of concrete structures was Japan’s major concern in the 1980s (Okamura & Ouchi, 2003). Japan faced a severe shortage of skilled workers in its construction industry, and compaction of concrete had to be performed by skilled workers to ensure durability of the concrete structures. Therefore, the development of self-compacting concrete that could fill every space of the formwork by virtue of its own weight without the need of mechanical vibration seemed a very promising alternative. This would also eliminate noise sensitivity, white finger syndrome and other environmental and biological inconveniences that resulted from the vibrations on site (De Schutter, 2007). The concept of SCC was first pr...

The Use of Reinforced Concrete in Modernism Essay

- The usage of concrete was explored by the Early Christian and Roman architects but fell out of use throughout the Middle Ages and Renaissance period. The material was only fully explored again in the later half of the 19th century but only for mundane purposes where the material was cheap, easy to work with, and versatile, but most importantly it’s fireproof characteristic. In 1870, the idea of reinforcing the concrete was born; steel rods were to be inserted to increase its strength. Taking this principle, Ernest Ransome (America) and Francois Hennebique (France) both developed frame systems....   [tags: Ernst Ransome, architecture, concrete]

Essay Concrete Poetry - A Unique Genre

- Concrete poetry presents its readers with a unique and often confounding situation. In addition to using language or parts of language in non-traditional ways, concrete poetry also uses elements that are more commonly associated with visual art. However, concrete poetry is not visual art. It is still concerned, primarily, with the use of language, generally to communicate some meaning to the reader in a way that is undeniably linguistic in nature. Concrete poetry is therefore an especially unique genre that draws upon and incorporates many different concepts from a variety of disciplines in order to fill in the gaps left when traditional grammar and syntax are eschewed....   [tags: Concrete Poetry Analysis]

Essay about The Constituent Materials of Concrete

- Portland Cement Association (n.d.) stated that in the simplest form, a blend of paste, stone, sand and water is a concrete. Concrete is one of the fundamental building block of the civilization, contributing to all the structures across the world. Concrete can be viewed in details in term of its constituent materials, properties, durability and concrete mix design and quality control. Constituent materials are the fundamental materials required to produce concrete. The constituent materials of concrete consist of mainly three materials which are cement, aggregate and water, with admixtures included as addictive to alter the characteristics of the concrete (Scalenghe et al., 2011)....   [tags: Quality, Constituent Materials]

Essay about Alternatives to Concrete

- Concrete today is considered by many modern engineers and architects as a more efficient and effective alternative to steel n regards to the creation of buildings, ranging from low-story apartments to neck-breaking skyscrapers. Through the rapid growth and development of the world's major metropolises and growing cities, concrete today has become one of the most important building materials to date. According to the World Business Counsel for Sustainable Development (WBCSD), “it has become the most consumed substance on earth, only superseded by water, with three tons for each person used annually” (World)....   [tags: Recycled Waste, Carbon Emissions]

- According to major supplies, “Use of synthetic fibers for reinforcing concrete is continuously, increasing. The increase has been considerable since 1980, but slowed somewhat in 1990, a year of substantial construction cutbacks. Apparently the construction community believes there are advantages in the use of synthetic fibers in concrete.” (Schupack) Synthetic fibers are used to improve crack control in concrete.
