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: if it is is it renewable or nonrenewable?
- Is Cement A Natural Resource
- Q: What would happen if the silica percentage is higher than 25% of the total weight of the Portland cement?
- Allow me to qualify my answer first. When mixing cement water, in the process and as it dries hardens, air pockets tend to form inside the concrete. Air pockets are like those holes that are inside the cheese we see when we cut it. Concretes could also tend to form air pockets as it dries up firms up. Those air pockets could WEAKEN the concrete, because of the spaces inside. Now, the function of silicon dioxide is it minimize those air pockets tends to make concrete stronger.
- Q: Start a new type of cement products building materials company, I would like to ask after the environmental protection project, qualification and related procedures can be issued directly can not how to take the procedure
- Know the king, put the second part, the other is wrong
- Q: We installed bamboo fencing on our garden to add height to our outdoor wall. when rain falls, the poles get filled with water. We thought of placing an improvised metal roofing on it as what we see on other houses' fencing but we thought it will make the fence's look a lot awful. So we decided to fill each poles with concrete. will this do harm to the quality of the poles? Is it wrong to fill bamboo poles with cement?
- Using concrete seems like a lot of hassle and expense. Instead, I suggest filling the stems with dry sand up to 1 cm, or so, from the top, then closing the top with a sealant such as silicone caulk.
- Q: more accurately how should one space floor boards on a cement slab subfloor? every 4quot;...6quot; also any recommendations on what type of plywood/board to use? should i use insulation or just concrete board?
- now i have to ask a question why do you need a sub floor on cement and how hi do you need it to be and what is you're finished floor so we can help if we have more info there is all kinds of answer's
- Q: i need some info on CEMENTED CARBIDE, its cost, its manufacture process, availability, its uses and applications.plz help ! thank u !-ABISH
- There okorder and search for carbide. Of course, there are other applications for carbide other than as cutting tools. Because it is extremely hard, it is uses as a bearing material, as extrusion nozzles, as sand blasting nozzles, for high temperature ball bearings, and many other things. Because carbide cutting tools withstand higher temperatures, they can operate at higher cutting speeds. This has enabled a relatively new form of machining aluminum, called high speed machining, in which large billets are aluminum are machined directly to the final shape needed, such as for aircraft parts. High speed machining eliminates casting operations (with the liklihood of defects such as voids and inclusions), as well as making complex assemblies by welding or rivetting smaller components. The result is higher quality with lower tooling cost. The development of carbide materials has changed the metalworking industry.
- Q: i need to paint cement. either in the process of doing the cement or after when its dry? which way is the best? it has to be really durable, waterproof.
- This Site Might Help You. RE: can i paint cement? i need to paint cement. either in the process of doing the cement or after when its dry? which way is the best? it has to be really durable, waterproof.
- Q: What's the qaulity, and how do they look in your opinion.
- The White Cements? If Yea, then YES! Very Nice Shoe, and The Quality Is Very Good, but it really depends on the price they are not worth spending 270+ $ For Them. If you can get them anywhere from under 230$ i would get them
- Q: homework
- Cement is a composite mixture of limestone, gypsum and clay materials.. the most common is Portland Cement. Mixed with water, sand you get concrete which is the primary ingredient for the construction of roads, bridges and buildings.. For massive projects, concrete binds together with steel to create a system of compression forces which counteracts with the tensile forces of the steel to give the structural strength needed for construction. Concrete can also be used as a means of screeding whereby you apply a layer on an unever surface prior to any laying of decorative tiles or marble flooring.. Applies the same for bathrooms etc.
- Q: Did anyone die in cement at hover dam?
- One construction worker fell to his death in the liquid cement during the building of the hover dam.
