为什么混凝土中使用微硅?
Micro silica, also known as silica fume or condensed silica fume, is a byproduct of the production of silicon or ferrosilicon alloys. It is composed of very fine particles (通常在 1 直径为微米) and has a high surface

We know that silica fume as a kind of admixture that can effectively increase the performance of concrete, 其流动性越好, 起到的效果就越好, 但流动性在测试前还不能很清楚, if the
In the construction of various building projects, it is always inseparable from the use of cement mortar, concrete and other building materials, and in order to ensure better performance of these materials, it is necessary to mix the appropriate amount
Silica fume is an essential component in the production of concrete. Silica fume is a mineral admixture derived from the burning of coal or other fuel sources, and it is composed of microscopic particles of silicon dioxide. This material provides
There are many factors to measure the quality of concrete performance, durability is one of the very important indicators, if the durability is not enough, will lead to serious consequences. 因此, in the concrete configuration, how to improve the durability
In order to make more effective use of silica fume on the improvement of the microstructure of hardened cement paste, many researchers at home and abroad have conducted more detailed studies on the optimal conditions for the application of silica
Conventional micro silica fume When ferroalloys are smelting ferrosilicon and industrial silicon (金属硅), a large amount of volatile SiO2 and Si gas is produced in the mineral-heated electric furnace, and the gas is discharged and rapidly oxidized and precipitated
Micro silica fume is essentially a “by-product” 或者 “waste product” of the smelting process, not through deliberate production and processing, so its quality is more subject to the influence of external factors. In order to make the product quality relatively
步 1: Exhaust gas purification The flue gas exported from the electric furnace passes through the fume hood, main flue gas pipeline, 经过冷却器冷却后进入旋风分离除尘器, and then passes through the
