In order to make more effective use of silica fume on the improvement of the microstructure of hardened cement paste, many researchers at home and
Med den stigende brug af mikrosilica-røg i cementbeton, ildfaste materialer og andre områder, det er gradvist ved at blive en almindelig materialemodifikationsblanding,
Silica-røg blev opdaget som et biprodukt af siliciummetalproduktionsprocessen. Imidlertid, det har vist sig at være af høj værdi takket være dets fysiske og kemiske egenskaber.
Microsilica, eller silica-røg, er et biprodukt fra produktionen af silicium og ferrosiliciumlegeringer. Når disse legeringer er lavet, a small amount of silicon dioxide
Silica fume is a good concrete admixture, refractory additive, chemical product dispersant and metallurgical pellet binder for its excellent properties of high temperature resistance, prevention
Lav højstyrkebeton (over C70) med silica damp, hvilket kan forbedre betonens styrke og pumpeydelse markant; Gør høj uigennemtrængelighed (≥ 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. F.eks, some admixtures can
Blending amount Generally 5-10% af mængden af cementholdige materialer. The mixing method of silica fume is divided into internal mixing and external mixing. Internal
