Pentru a utiliza mai eficient fumul de silice pentru îmbunătățirea microstructurii pastei de ciment întărite, many researchers at home and
Odată cu utilizarea din ce în ce mai mare a fumului de micro silice în betonul de ciment, materiale refractare și alte domenii, devine treptat un amestec comun de modificare a materialelor,
Silica fume was discovered as a by-product of the silicon metal production process. Cu toate acestea, it has proved high-value thanks to its physical and chemical properties.
Microsilica, or silica fume, is a by-product of the silicon and ferrosilicon alloy production. When these alloys are made, a small amount of silicon dioxide
Fumul de silice este un bun aditiv pentru beton, aditiv refractar, dispersant de produs chimic și liant metalurgic de peleți pentru proprietățile sale excelente de rezistență la temperaturi ridicate, prevention
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, high resistance to deformation, high density and other characteristics, 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. De exemplu, some admixtures can
Blending amount Generally 5-10% a cantităţii de materiale cimentoase. The mixing method of silica fume is divided into internal mixing and external mixing. Internal
