Introduction

96% Densified Silica Fume is a micro-silica fume with 96% SiO2 content, and the Bulk density is 250-400kg/m³.

Silica fume has been used to improve refractory materials for more than 40 years. Silica fume used in refractory materials will have the following characteristics:

1. Improve the flowability of pouring refractory, reduce water consumption, make it easy to shape, and greatly improve the production efficiency;

2. Due to the intercalation effect of its ultrastructure, the compactness and strength of refractories are greatly improved;

3. Silica fume has high activity, and under the premise of the presence of Al2O3 components, it is easier to generate Mullite phase, which makes the high-temperature strength and thermal shock of refractory material significantly improved.

Applications

  • Water conservancy and hydropower engineering: in the anti-seepage and anti-abrasion parts, after mixing with micro-silica powder, it can greatly improve the anti-seepage, anti-cracking, anti-abrasion and anti-cavitation performance.
  • The production of high-strength concrete: silica powder as admixture to make high-strength concrete, the actual application of its strength level can be achieved 100Mpa.
  • Seaport engineering: concrete mixed with silica powder can improve the concrete’s anti-abrasion performance, anti-seepage performance, to prevent electrochemical corrosion of reinforcing steel.
  • Traffic engineering: silica powder concrete used in highway pavement and aircraft runway, can greatly improve the early strength and wear resistance of concrete, in the maintenance and repair of highway pavement, you can advance the opening time and increase the economic benefits.
  • Shotcrete: significantly improve the adhesion performance and cohesion of plastic concrete, significantly reduce the amount of rebound, increase the thickness of shotcrete once formed, shorten the construction period and save the cost of the project.

Packaging

The only silica fume factory in China that uses machine packaging.
We can also produce according to your requirement.
The machine is automatically packed and filtered by a screen, so that no debris is mixed in.
