Instruction
*Microsilica , also called silica fume or micro silica, is a byproduct of producing silicon metal or ferrosilicon alloys.
*Silicon metal and alloys are produced in electric furnaces. The raw materials are quartz, coal, and woodchips.
*The smoke that results from furnace operation is collected and sold as silica fume, rather than being land filled.
*Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2), its average granule diameter is 0.15~0.20 µm,specific surface area is 15000~20000 m2/kg, and it has extremely strong surface active.
*Microsilica can be used in a variety of cementation products, such as concrete, grouts, and mortars as well as elastomeric, polymer, refractory, ceramic and rubber applications.
*HS No.: 28112200 China Origin, microsilica meets the requirements of ASTM C-1240.
*Microsilica CAS #: 69012-64-2
Main function
*Very low permeability to chloride and water intrusion.
*Extremely high electrical resistivity (20 to 100 times greater than ordinary concrete).
*Increased abrasion resistance on decks, floors, highways and marine structures.
*Superior resistance to chemical attack from chlorides, acids, nitrates and sulfates.

- Q:My contractor charged me $450 for cement for laying out 600 sq ft tile on the floor. He told me he used 27 bags. This is in addition to grout. Cost seems very high. How many bags is typically needed?Thanks a lot
- Even if your floor is only 600 sq. ft but if its uneven then chances are he really consumed that much of cement bags. If your contract states, installation only then you will have to pay the contractor for the additional materials he used which was needed to complete the job.
- Q:Im trying to remove my Backsplash! Old Tiles gone! Whats the best way to remove Cement Board without damaging my Drywall? I made a hole but need the best way to prevent more!
- depending on how old the house is, the sheetrock could be different - past 5-6 years they have built better sheetrock (older sheetrock is more likely to crumble no matter what you do). First you have to see if it is glued, nailed or screwed on. If it is glued, you are better off replacing your sheetrock so you have a better substrate for your new backsplash. If nailed, it should come off easy, and if screwed, you can see the screws in order to back them out. Good luck - hope it works out.
- Q:Why will quarries (cement factory places) reduce carbon dioxide emissions?
- Cement plants - not so much the quarries (although their motorized industrial vehicles will also have to start improving performance). The production of cement starts with limestone (CaCO3) plus some additional bits to provide Si, Fe and Al. The whole lot is put into a rotating kiln that roasts the mixture. CO2 off-gases, leaving high-temperature Ca-Si-Al-Fe-O compounds that form the clinker for portland cement. Because modern (and developing ) societies use huge amounts of cement for construction uses and buildings, roadways, bridges, airport runways ... - enormous amounts of limestone are roasted, releasing CO2. Look at the molecular/atomic weights, and you;ll see that 44% by mass of all the CaCO3 that is treated will report to the environment as CO2. Mark L.
- Q:where can i buy refractory cement mix?
- You can get refractory cement mix from North Refractories Co. LTD. North Refractories Co. LTD (NRCL) is a China leading refractory and ceramic fiber insulation products manufacturer supplier with an wide range industries focused where high temperatures exist. NRCL Products include ceramic fiber insulation materials, refractory firebricks, castable refractory, calcium silicate insulation products. Trusted Welcomed for more than 20 years, we are waiting for your contact and inquiry.
- Q:how do you resurface cement steps?
- First check the quality of the cement, it may be inferior to construction standards. When you determine it is good, then you need to rough up the surface with a tool like a chisel to give the new surface a grip. Mix a screened sand with some portland at a 2 to 1 mix and trowel it on with a steel finishing trowel
- Q:What is the value-added tax rate of sand, soil and stone?
- Tax rate of 3%, the tax rate of 17%.
- Q:How to lay cement blocks?
- Remove 4-6 inches of soil/sod, lay geotech fabric, compact 4-6 inches of D-1 gravel in 2 inch lifts, grade to drain away from structures, screed 1 inch of sand or stone dust and lay blocks on sand. Tap with rubber mallet then sweep sand into the cracks.
- Q:I'm a student, now studying about derivatives. In type of commodity options, why do we have wheat options, oil options, gold options... why don't we have cement options?And please let me know, is there any qualification, any criteria for choosing a goods to be an underlying asset of a derivative?
- Don't be intimidated by the charts, actually they are not that hard to read and understand. Strategies that are based on reading and analyzing charts are part of the technical analysis area.
- Q:Is the cement used for dental crowns antibacterial?
- There are some basic composition cements used for cementing crowns.Most of them are based on Powder and Liquid ratio.Most commonly used are GIC( glass ionomer cement),The reason its used so widely that 1.It creates a chemical bond with tooth structure. 2.It leeches out the Fluoride ions for a prolonged time after it sets in order to provide protection. Now a days the use of Resin based cements are on the rise as they are easy to handle , create a good seal and also have fluoride action as mentioned previously. U can visit link as under the source as under.
- Q:please tell me the order of increasing strength of cement mixtures1)cement mixed with river sand 2)cement with lime3)cement with pitsand4)cement with rice huski think order is 2 gt; 3gt;4gt;1 (strength)i am not sure.please tell me the correct answer along with explanation.
- we assume the cement (Portland cement) is of the correct ratio. we also assume we are talking about compressive strenght when we have just enough cement to fill the spaces between the rock we have reached the maximum strength. number 2. is no good as it reacts with the cement mixture number 4. allows for compression and cracking of the cement. number 3. .....pits i dont know what is pits number 1. is the same as rock ......the best here so .... the order my guess ....... 2,4,1
