The cement is the common construction material, Industrial used in Portland cement fineness range between 100-300 mesh; And requiring a superfine cement particle diameter D50 can fine below 1 um, that nanoscale the largest diameter does not exceed 18 um on3dmax, more than 80% of the particle size below 5 um, what the superfine cement vertical mill?
Research found that the particle size of ultrafine cement slurry has the very good can be made of sex, can penetrate into the generally think of cement particles cannot penetrate fine powder sand mixing layer, silt layer and soil layer. It can be used in more than 4.0 under high water cement ratio, under high water cement ratio has high sand consolidation strength, and can meet the requirement of grouting construction, and achieve high durability and low cost.
The current production of superfine cement is not only the trend of the development of construction industry, is also a lot of engineering industry must material, the fineness of superfine cement probably between 800 mesh and 2500 mesh, such as high fineness must use superfine grinding machinery and equipment, and the most professional equipment production enterprise.
