WebJan 1, 2024 · Self-compacting concrete (SCC) (“self-consolidating concrete” in North America) is a family of tailored concretes with engineered properties in the fresh state. SCC is characterized by its ability to flow into the formwork under its own weight and without segregating. Therefore the key engineering properties of fresh SCC are filling ability ... WebSelf compacting concrete (SCC), also known as self-consolidating concrete, is a special concrete mix exhibiting high flowability, good segregation resistance, and ability to self …

WebImpacto ambiental do concreto. O impacto ambiental do concreto, sua fabricação e aplicações são complexos, impulsionados em parte pelos impactos diretos da construção e infraestrutura, bem como pelas emissões de CO 2 ; entre 4-8% do total das emissões globais de CO 2 vêm do concreto. [ 1] Muitos dependem das circunstâncias. WebMineral admixtures (fly ash, silica fume (SF), and slags) are usually added to concrete in larger amounts to enhance the workability of fresh concrete; to improve resistance of concrete to thermal cracking, alkali-aggregate expansion, and sulfate attack; and to enable a reduction in cement content. Fly ash Silica fume Webof self-compacting concrete mixes. The test results for acceptance characteristics of self-compacting concrete such as slump flow; J-ring, V-funnel and L-Box are presented. Further, compressive strength at the ages of 7, 28, and 90 days was also determined and results are included here. Key Words: Self-compacting Concrete; Fly Ash; Mix pho in penticton
