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
Make high strength concrete (above C70) with silica fume, which can significantly improve the strength and pumping performance of concrete; Make high impermeability (≥ P30),
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
Silica Fume Silica fume contains a large number of non-crystalline spherical particles of SiO2 with extremely fine particles and strong activity, which are mixed into
