TOPKEN silica fume is a highly effective pozzolanic material, so it's easy to come into being Mullite Phase.

The uses for TOPKEN silica fume in concrete fit into general categories of enhancing mechanical properties, improving durability, enhancing construct ability.

1. Making high-grade concrete effectively enhances the strength  and pumpability of strong concrete. 

2. Making high crack-resistance, self-waterproofing concrete, be used in the subway, tunnel and basement of high-rise structures.

3. Used in maritime works and chemical industry. Owing to the compactability, it can prevent effectively sulphate and chlorine ion from osmosizing and eroding Avoid the steel corroding in armoured concrete (RC), lengthen the life-span of concrete.
