Silica fume, also known as micro silica or condensed silica fume, is a by-product of industrial processes like the production of silicon alloys and ferrosilicon. Anyang Lishi Industrial Co., Ltd. is a leading manufacturer of this remarkable material, composed primarily of silicon dioxide (SiO2). Silica fume is characterized by its fine particle size, typically ranging from 0.1 micrometer to 1 micrometer, resulting in an incredibly high surface area.
Performance of Silica Fume:
1. Ultrafine Particle Size and High Surface Area: Silica fume possesses an extremely small particle size, enhancing its surface area significantly. This property facilitates chemical reactions with water and cement, boosting its reactivity.
2. High Reactivity: Due to its minute particle size and extensive surface area, silica fume exhibits high reactivity, accelerating the hydration process of cement and enhancing both the early and ultimate strength of concrete.
3. Filling Effect: Silica fume can fill the internal voids of concrete, improving its density and compactness, subsequently enhancing the concrete’s strength and durability.
4. Improved Rheology: The addition of an appropriate amount of silica fume can enhance the fluidity and permeability of concrete, facilitating ease of construction.
5. Outstanding Mechanical Properties: Silica fume significantly enhances the compressive, flexural, and tensile strength of concrete, improving its mechanical performance.
6. Enhanced Durability: By reducing the porosity and permeability of concrete, silica fume improves its resistance to permeation, freeze-thaw cycles, chemical attacks, and overall durability.
Functions of Silica Fume:
- Enhanced Concrete Strength: Silica fume reacts with the calcium hydroxide in cement to form calcium silicate hydrate, improving the strength of the concrete.
- Improved Durability of Concrete: Through its filling and reactive properties, silica fume reduces permeability, enhancing durability and extending the service life of the concrete.
- Cement Savings: By incorporating silica fume, we reduce the dependency on cement, resulting in cost savings and demonstrating our commitment to environmental sustainability.
Applications of Silica Fume:
- Concrete Engineering: Silica fume, produced by Anyang Lishi Industrial Co., Ltd., finds widespread use in concrete and high-performance concrete, self-leveling concrete, high-strength concrete, and refractory materials, enhancing strength, durability, and quality in various construction projects.
