Heavy density silica fume for highspeed station cement

heavy density silica fume for highspeed station cement:This black silica fume is generally added to the cement used in the construction of high speed railway stations.

The role of encrypted silica Microsilica in concrete paste is obvious, and its mechanism of action is through both physical and chemical aspects.As a result of both physical and chemical mechanisms, changes in the microstructure of the paste, such as reducing permeability, particle filling, etc., can be seen.Encrypted Silica Fume in the concrete system, the need for adequate mixing and dispersion, need to be the first to join the coarse aggregate, play a strong abrasive effect, after high-power mixer for dispersion, fewer clusters can be relatively well dispersed, and silica fume volcanic ash reaction play a role in improving the interfacial transition zone, so that the compressive strength of the concrete to improve.

Summary: The benefits of encrypted silica fume are 1, easy to transport, 2, the use of the process does not dust. 3, reduce production costs.
