Introduction
85% Undensified Silica Fume is a micro-silica fume with 85% SiO2 indhold, and the Bulk density is 250-400kg/m³.
Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys. It consists primarily of amorphous silicon dioxide (SiO2), its average granule diameter is 0.15~0.20 μm, specific surface area is 15000~20000 m2/kg. Mainly used for high transparency, high resistance to tear silicone rubber, silicone grease, sealed packaging materials such as capacitors.

Ansøgninger
- Vandkonservering og vandkraftteknik: i anti-nedsivnings- og anti-slid-delene, efter blanding med mikrosilicapulver, 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: silicapulverbeton, der bruges i motorvejsbelægninger og flybane, kan i høj grad forbedre betonens tidlige styrke og slidstyrke, i vedligeholdelse og reparation af motorvejsbelægning, du kan fremrykke åbningstiden og øge de økonomiske fordele.
- Sprøjtebeton: markant forbedre vedhæftningsevnen og sammenhængen af plastbeton, reducere mængden af rebound markant, øge tykkelsen af sprøjtebeton, når den er dannet, forkorte byggeperioden og spare omkostningerne ved projektet.
