Product Description:

1.Microsilica 85%-98%

2.High fluidity

3.Low permeability

4.Meets the requirements of ASTM C-1240 

 

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:How long does plastic roofing cement take to dry?
Plastic Roofing Cement
Q:Which is the main mineral in cement ?
gypsum is a construction mineral, it is what makes up wall board which is used in most homes and offices buildings. but it is not a part of cement. portland cement is made from Limestone and Clay minerals. Those are heated together to make a cllinker that is further refined to make the product that goes into bags of cement.
Q:How to make cement weights?
You'll need; 1 1/2 black iron pipe x 4 ft L., 40 lb bag Quik-Krete, (2) one gallon milk jugs Cut a hole in the side of each milk jug to fit the pipe Insert the pipe in the holes and at least half way through the empty jugs Mix the cement and pour half in to each jug and let set over night Cut the plastic jugs off You now have a dumb-bell to use, but, you'll have to weigh it to see what you are lifting
Q:Did anyone die in cement at hover dam?
Why would you want to know that girl. Hush yo mouth!
Q:Does rubber cement float?
depends if it has a higher or lower density than water
Q:i think i have a allergy to the to the dentists cement?
Modern dentists usually use methal arcylate cement. Allergies to arcylates are extremely rare, but rare does not mean non-existent. So it is possible that you are indeed allergic to the cement. An allergist physician can probably test you to see if that is your problem. In the old days, before arcyclates, dentists sometimes used zinc phosphate as a cement. You might talk to your dentist to see if he can get that to use on you. (It might help if your dentist is older. I suspect many recent graduates have never even heard of alternatives to arcylate cement.) If that doesn't work, check in your area to see if there are any dentists who hold out as being natural, homeopathic, or similar terms. They may offer alternative treatments and alternative cementing compounds.
Q:Can I lay vinyl flooring over cement backer board?
Cement backer board is for use under tile. I have not seen anyone try to put vinyl over it. I would avoid doing this if I were you. 1/4 luan plywood is common for use underneath vinyl flooring. It provides a smooth, uniform surface to work with.
Q:How do you make cement?
Please be clear. Do you mean how do you make concrete? or how do you make cement? If you mean how do you make concrete, get 1 part cement, 2 parts sand and 4 parts gravel, mix with water until it's a stiff workable consistancy. Wait 24 hours for concrete to become reasonably cured to continue construction.
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:can you make paint from cement mix?
You can use powdered cement products mixed with a bonding solution as the liquid to enhance their stickiness, and you can also use concrete dyes to match a lot of different colors. These products are available at most big box retailers in their concrete area. The dyes are about $6 for a 12 oz. bottle
