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: the big pieces came from a old cement gold fish pond in my yard .
- best bet sledge hammer easy way eletric jack hammer home depo rents them good luck
- Q: i am making a disc golf course tee for my boy scout eagle project. i know a little about cement, but for anyone who knows a lot about cement construction, can you explain this...i need to make a rectangular and circular tee(which is a cement platform where one would stand while throwing a disc). the circle has a diameter of 11ft and rectangle is 11x9. I will be building it on dirt, which is level. I think i will need to dig a hole in the ground in the shape i want. then i have some gravel to put in. then cement in the hole. anyone know how much gravel, or if any, i should put in before i lay in the cement in the hole? thanks people!
- First, what you want is concrete, not cement. Concrete is a mixture of sand, gravel and portland cement. 6 of concrete will give you a permanent installation (20 years). Dig out 2 below level and put 2X4's around the edge. Make sure the 2X4's are well braced. You won't need any additional gravel. Fill the form with the concrete. You need to do this in one pour. You should not do it a few bags at a time, so you'll need a lot of buddies with wheelbarrows unless you plan to get a truckload. If you want to do an especially good job lay wire fencing in the concrete half way through the pour. That will give you a reinforced concrete slab that will last 100 years. When you smooth the top, make sure it's slightly higher in the center for drainage.
- Q: What is cement asbestos and where was it used? Is it basically just sheeting that is/was used to insulate housing (kinda like siding)? We were sanding/grinding a cement wall in the company front yard, and I was just wondering if this could have been labelled as cement asbestos. I don't know if it contains asbestos, but it is just a cement/concrete wall that contains the company name. Thanks.
- Poured cement such as walls, slabs, driveways etcetera did not contain asbestos..just concrete sheet products also known as Fibro..it is still called fibro in oz but it now contains no asbestos..here is a link
- Q: what is the best kind of cement for filling cracks in foundations?
- I would not suggest cement. There are epoxy systems for strucural repairs or several types of products for water infiltration. Using cement will cause a mess and won't do either of the above with small cracks.
- Q: Will the building materials cement 425 and 325 labels have any difference in the quality of the impact of life, please tell me please?
- This can go to Google check, do not put this question, the answer is too much.
- Q: I went to Home Depot and they said there was no such thing, all cement bags have rocks, is this true? If I went to Home Depot to buy a bag, what would it say on the bag?
- I guess by rocks you mean aggregate, i.e. small stones. You can mix concrete without aggregate but it's not as strong. Pretty much any time you mix concrete it will have aggregate in it and you should be using rebar or wire mesh to reinforce it.
- Q: Is the cement industry in the stock a separate plate? Or part of the other plate?
- Some software is listed as a separate plate, some software is classified as cement building blocks, some for the infrastructure sector, see what software you use!
- Q: I've had braces and had a permanent lower retainer put in. Well the dentist removed it today and never scrapped the cement off of the back of my teeth. Anyone know of a way that I can get it off at home without having to go back to the dentist?
- Nope. i've got had braces for over a month and after eating soda, no longer something surpassed off. If this is on your mouth, i'm specific this isn't any longer poisonous hun. i could propose no longer eating soda as plenty, however, via fact soda motives cavities fairly and a hollow area with braces could basically reason the orthodontist to could desire to maintain them on plenty plenty longer. this is extra constructive to basically drink water or yet another helthy dtink besides, as soda is fairly risky do to the severe fructose corn syrup and all the energy.
- Q: How is cement used to make concrete?What are the principle types of concrete and how are they made?
- We added sand, rock and water to cement to make a boat ramp, diving board platform, a seawall secured with pilings that went across two lots that included a patio and boat dock. We used different concrete mixtures since the seawall was poured in a form with reinforced steel that was in the water. The cement was poured through a large plastic tube. The pilings also had a plastic tube which we had water running through to help get them into the ground. And on one the learning channels I remember that the Autobahns has held up better than our roads because it had a deeper foundation, I believe it was 2 inches deeper. I imagine that there are different mixtures for concrete depending on the purpose it is for and the weather. This is from 45 years ago memories, so check it out.
- Q: I've tried hosing it down, sweeping etc. Nothing seems to work. Can anyone recommend a solution for my problem?
- Cement residue i presume what you really mean is the dusty stuff that keeps coming off of cement as it wears away for ever and ever. First if it's uneven lumps or spills and spots you have to pomice ( wear down the rough spot with pomice the cement with pomicingstone which usually has a wood handle and it is harder than cement especially poorly cheaply made cement used by builders andcontractors for extra profit. after dong that you go buy linceed oil and seal the floor with several coats lasts almost forever indoor. Second alternative is buy (very costly) slate and cement sealer. in 1974 it cost me $20. a gallon it took about 3 gallons to do 1100 sq. foot. basement. many builders mix too much sand and not enbough cement to make Concrete
