With the increasing use of micro silica fume in cement concrete, refractory materials and other fields, it is gradually becoming a common material modification admixture,
Silica fume was discovered as a by-product of the silicon metal production process. 然而, it has proved high-value thanks to its physical and chemical properties.
Make high strength concrete (above C70) with silica fume, which can significantly improve the strength and pumping performance of concrete; Make high impermeability (≥ P30),
Ultra-high performance concrete has high compressive strength, 高抗变形能力, 高密度等特点, mainly because of a variety of mineral admixtures added
Concrete admixtures are added to concrete mixtures to give them certain characteristics that make them more suitable for specific applications. 例如, some admixtures can
Blending amount Generally 5-10% 胶凝材料的用量. The mixing method of silica fume is divided into internal mixing and external mixing. Internal
In concrete and refractory materials, often use silica fume as admixture, so as to improve the performance of materials, usually in concrete mainly to improve
