Bemsun Industry Co., Ltd

Company Description

Bemsun provide various of grade of microsilica for cement. Which it is as a admixture for cement and improve the cement performance in construction.Microsilica, is a byproduct of producing silicon metal or ferrosilicon alloys. Mine electric furnace generates mass very reactive SiO2 and Si gas. The gas was oxidation and condensation precipitation with air rapidly.Microsilica ? building a durable future into the infrastructure of seaport, high building, reservoir dam, Railway, driver road, bridge, metro, tunnel, airport runway, coal lane and etc.Cement microsilica main features:* High early strength* Greater impermeability* High ultimate compressive strengths* Substantially greater resistance to corrosionCement microsilica technical COA analysisSiO2: 92%minFe2O3: 0.2%Al2O3: 0.2%LOI: 3%maxMositure: 1.5%Specific surface: 18kg/m2Bulk Densify: 500-700kg/m3Microsilica admixture is used in cement performance:Microsilica admixture fill the pores of cement particles, and generate gel with hydration and magnesium oxide reacts with alkaline gel material. microsilica admixture is widely used in cement, the performance are as following: 1. Improving the compression, bending, impermeability, anti-corrosion2. With water retention, prevent segregation, significantly extend the service life of concrete.3. Prolong the life of concrete, especially in chloride, polluted erosion, sulfate attack, high humidity and other harsh environment. 4. Reduce in jet landing castable concrete and ash, rasing a single spray layer thickness5. Microsilica is a necessary component of high-strength concrete6. with about five times the efficacy of cement with microsilica admixture7. Prevent the occurrence of concrete alkali aggregate reaction8. Improve the compactness of the cast refractory material.
