Concrete Admixture Microsilica Grade 90

详情

Bemsun manufacturer series of microsilica admixture for concrete. Like - concrete microsilica grade*5, concrete microsilica grade*0, concrete microsilica grade*2.Which play good performance with cement and concrete in construction business.

1. Instruction of Concrete Microsilica
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 admixture in concrete,  build a durable future into the infrastructure of seaport, high building, reservoir dam, Railway, driver road, bridge, metro, tunnel, airport runway, coal lane and etc.

2. Concrete microsilica main features:
* High early strength
* Greater impermeability
* High ultimate compressive strength
* Substantially greater resistance to corrosion

3. Microsilica admixture specification
SiO2: *0%min
Fe2O3: 0.2%
Al2O3: 0.2%
LOI: 3%max
Mositure: 1.5%
Specific surface: *8kg/m3
Bulk Densify: ******0kg/m3

4. Microsilica admixture performance in Concrete & Cement:

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: 

A. Improving the compression, bending, impermeability, anti-corrosion

B. With water retention, prevent segregation, significantly extend the service life of concrete.

C. Prolong the life of concrete, especially in chloride, polluted erosion,sulfate attack, high humidity and other harsh environment. 

D. Reduce in jet landing castable concrete and ash, rasing a single spray layer thickness

E. Microsilica is a necessary component of high-strength concrete

F. with about five times the efficacy of cement with microsilica admixture

G. Prevent the occurrence of concrete alkali aggregate reaction

H. Improve the compactness of the cast refractory material.
