Silica Fume is often used as cement or concrete admixture in the construction industry, che può riempire i pori tra le particelle di cemento e migliorare efficacemente le sue proprietà di compressione e ritenzione idrica. Il componente principale dei fumi di silice è il biossido di silicio,
With the increasing use of micro silica fume in cement concrete, refractory materials and other fields, it is gradually becoming a common material modification admixture, in order to make the modification of materials more applicable to the project, microsilice
Refractory materials are divided into two types, one is the fixed material and one is the indefinite material, the castable refers to the indefinite refractory material. We know that micro silica fume is a good refractory additive, which can improve
Although silica fume is a by-product of large industrial smelting, it plays a very important role in many industrial fields, so few people in the relevant industry fields do not know it, silica fume is not only alias a lot,
Generally speaking, the silica content is a measure to test the quality of micro-silica fume. The higher the SiO2 content, the higher the performance of microsilica fume and the lower the content of other non-SiO2 impurities. Perciò, the methods of
There are more methods for testing the strength of commercial micro silica fume, and the commonly used methods are rebound method, ultrasonic rebound synthesis method, pull-out method, and core drilling method. Tra loro, rebound method and ultrasonic rebound synthesis method
There are different types of micro silica fume according to different classification criteria. In terms of supply form, it can be broadly divided into two categories, one is the undensified silica fume also said to be the raw silica fume,
FUME DI SILICA, also known as microsilica fume, is a fine powder collected as a by-product of silicon and ferrosilicon alloy production. The product is used in concrete to improve strength and durability. Low demand for silica fume If you have
Microsilica, or silica fume, is a by-product of the silicon and ferrosilicon alloy production. When these alloys are made, a small amount of silicon dioxide and other materials are vaporized and condensed. This results in a very fine powder ,con
Fume di silice densificato, is a further processing of the original micro-silica fume to obtain a denser encrypted micro-silica fume.
