Introduction
99% Undensified Silica Fume is a micro-silica fume with 99% SiO2 indhold, and the Bulk density is 250-400kg/m³.
Silica røg, also called Microsilica or micro silica, is a byproduct of production silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces.The raw materials are quartz,coal and woodchips. The smoke that results from furnace operation is collected and sold as silica fume, silica fume consists primarily of amorphous(non-crystalline) silicon dioxide(SiO2), its average granule diameter is 0.15~0.20um, specific surface area is 15000~20000m2/kg,and it has extremely strong surface active.
Basic Attributes
- Very low permeability to chloride and water intrusion.
- Extremely high resistivity (20 til 100 times greater than normal concrete).
- Increased abrasion resistance of decks, floors, highways and marine structures.
- Excellent resistance to chemical attack by chlorides, acids, nitrates and sulfates.
Fordele
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.
