The role of densified silica fume in pulp and concrete

The role of densified silica fume in pulp and concrete

Blogs
As an admixture, silica fume has been widely used in the preparation of high-strength concrete. It can reduce the use of cement clinker. Because of the strong activity of silica fume, pozzolanic reactions and micro-aggregate filling effects can occur in the concrete. The incorporation of silica fume in high-strength concrete…

Micro silica fume used in thermal insulation materials

Micro silica fume used in thermal insulation materials

Blogs
Thermal insulation materials are usually light, loose, porous and low thermal conductivity materials. The thermal conductivity of commonly used thermal insulation materials is less than 623K (350 ℃), and the thermal conductivity should be less than 0.14W / (M. K). Thermal insulation material can slow down heat flow rate produced…
