Self-consolidating concrete (SCC) with mineral admixtures is a type of concrete that uses mineral admixtures to improve its properties and performance. SCC is a highly flowable, non-segregating, self-compacting, and highly workable concrete that can fill the formwork and molds under its own weight without any need for external vibration or compaction. Mineral admixtures are added to SCC to improve its strength, durability, workability, and other properties.
The purpose of using SCC with mineral admixtures is to improve its properties and performance in various applications. SCC with mineral admixtures is used in various construction projects, including high-rise buildings, bridges, tunnels, and other infrastructure projects. Some of the benefits of using SCC with mineral admixtures include:
- Improved workability: SCC with mineral admixtures has excellent workability, making it easy to place and finish. It flows easily and fills even the most complex formwork.
- Enhanced durability: The addition of mineral admixtures to SCC can improve its durability by reducing permeability and increasing resistance to chemical attacks, abrasion, and weathering.
- Better strength: SCC with mineral admixtures can achieve high strength due to the use of pozzolanic and other mineral admixtures, which react with the cement to form more C-S-H gel, improving the strength of the concrete.
- Reduced environmental impact: SCC with mineral admixtures can reduce the environmental impact of concrete production by using waste materials such as fly ash, slag, and other mineral admixtures that would otherwise go to landfills.
There are various types of mineral admixtures that can be used in SCC, including fly ash, slag, silica fume, and metakaolin. These admixtures can be used alone or in combination to achieve the desired properties and performance of the SCC.
In summary, SCC with mineral admixtures is a highly workable and durable concrete that can be used in various construction projects. The addition of mineral admixtures can improve its properties and reduce its environmental impact, making it an attractive option for sustainable construction.
