  • Essay / Concrete Technology In Concrete - 1205

    The development of new technologies in materials science is progressing rapidly. Over the past three decades, much research has been carried out around the world to improve the performance of concrete in terms of strength and durability. Consequently, concrete no longer remained a construction material but rather became a tailor-made material with several new constituents to meet the specific needs of the construction industry. The increasing use of concrete in special architectural configurations and closely spaced rebars have made it very important to produce concrete that ensures adequate filling capacity, better structural performance and adequate durability. Concrete technology has been the subject of studies at the macro and then micro level in improving concrete properties (strength and durability) since the early 1980s. In Japan, in the early 1980s, premature deterioration of concrete concrete structures has been detected in almost all regions of the country. The main cause of deterioration was found to be inadequate compaction. To solve this technical problem, the concept of self-compacting concrete was introduced. SCC is a type of concrete that flows on its own without segregation, does not require vibration for complete compaction and is environmentally friendly due to the absence of noise. Self-compacting concrete offers robust construction and is insensitive to the quality of workmanship. BASIC PRINCIPLE OF SELF-COMPACTING CONCRETE (SCC) SCC is that which is compacted due to its own weight and is deaerated (no entrapped air) almost completely while flowing into the form work. In densely reinforced structural members, it completely fills all voids and maintains the horizontality of the concrete surface after placing the middle of the paper...... to increase durability compared with ordinary concrete.5. SCC exhibits narrow variations in site properties.6. SCC is most suitable for the construction of concrete filled tube (CFT) technology for high-rise buildings.7. SCC ensures better quality of pile foundations in situ.8. SCC reduces the resource consumption cost and cost. Self-compacting concrete (SCC) is particularly suitable for highly reinforced concrete elements such as bridge decks or abutments, tunnel linings or tube segments, where it is difficult to make the concrete vibrate, or even for building structures. normal engineering. Improved construction practices and performance, combined with health and safety benefits, make SCC a very attractive solution for both precast concrete construction and civil engineering. Based on these facts, it can be concluded that SCC will have a bright future..
