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 do i seal cement?
- spray it with a cheap garden sprayer of roll it on with a long handled roller...get a good sealer from your local concrete plant ...
- Q:Say a person was in a large tub and they filled the tub with wet cement and it was to be filled right up to the persons shoulders leaving his neck and head sticking out? Like after the block of cement hardens? Would the person die?just curious.
- The person would die painfully and pretty quickly. As soon as the cement started to harden, the cement would crush the ribs, probably jabbing the heart or other vital organs. If, say you did live through that... You're still stuck in a tub of freaking cement.
- Q:While cleaning out the garage of a home I recently bought, I found a sealed unlabeled tub with a cement (or concrete) mixture inside. Is there a way to tell if it is Portland, Quickrete, Sakrete, or whatever? Thanks.
- It really don't matter what it is, sealed or not, all the products you mentioned are only good for so long then break down and then are all called by one name. Garbage. As you have no idea as to how old it is, thats the name of it.Garbage
- Q:We have an awkward spot in our basement heading down the stairs. We barely have enough spaace to bring bigger items down. We would like to put a 3/4 drywall and glue it to the wall. Is this possible? Can I just use liquid nails?
- The problem is that drywall is faced with paper, and your concrete will tend to pass moisture from the soil. So after some time, there will be mold on the back of your drywall. The right way to do this is to spike pressure treated sleepers to the concrete, and nail the drywall to the sleepers/ This will create an air space that will tend to keep the drywall dry. A much better approach would be to apply a coat of stucco to the cement wall. The stucco is totally inorganic, and would breathe just like concrete. This can be coated with a basement wall paint.
- Q:I know they say babies don't keep a man but it is a lifelong commitment so why not?weather the relationship is good or bad I truly do believe a baby is a way to cement that man into your life?Why do I feel like this?
- I think its Absolutely sick when a woman decides to get pregnant on purpose just so the man has to stick around, and usually, this blows up big time in these woman's cases. And how selfish to bring a child into the world for that reason? A romantic relationship and a relationship with a man is two very different things, my husband and I would be lying if we said we were romantics, its a small part of our relationship and I dont get the correlation between a romantic relationship and having a child, I just dont get that statement at all. Many couples decide to have a child because they want a family, it isn't to prove there love to themselves (or at least shouldn't be) or to others, its a choice in their relationship
- Q:What should I do about the corners? Do they require cement pillars? The garage is about 25' by 20'. What brand or type of cement is recoommended. Here in Texas, the ground shifts because of the high clay content. A car or SUV may be parked on the cement.
- if ground shifts a lot why no use 3 inch thick patio slabs 3ft by 3 ft you would only need 24 of them and then you need to level with sand in this case if ground does shift all you would have to do is remove put down more sand and back to level again and if the garage needs to be reinforced then do so at the same time but make it a floating one
- Q:WHY is chemical cement less abundant in SHALE? WHY is it variable in conglomerate?
- Chemical cement in shale is less abundant because shale particles are so small can normally bind the rock together without an additional bonding from a chemical cement. Chemical cement in sandstone (NOT part of your question), is much more abundant because the particle size - normally visible quartz grains - is such that the rock would disintegrate, as unconsolidated sand, if it were not present. Chemical cement in conglomerate is variable because conglomerate is variable. Is the conglomerate pebble supported or matrix supported? A pebble supported conglomerate may be bound together with a later chemical cement. A matrix supported conglomerate may be bound by the sand or clay rich matrix which will not require any later infilling cement.
- Q:How can I dizzolve the cement that the dentist puts in you mouth to seal in a pallet expander? Can i use a house hold fluid? Or can i chip it away? Or what?
- Play it safe an dgo back to the dentist. The cement will dissolve in saliva over a very long period of time. (months to years)
- Q:why must you use cement board under ceramic tile?
- It is not necessary to use cement board under ceramic tile unless the area is gong to be exposed to water or moisture frequently. The cement board creates a water barrier to protect the wood framing of the house. Ceramic tile can be successfully laid over wood, plastic, fiberglass or any other surface that is flat and solid. That means no give or flexing when you walk on it or sitting things on it. A wooden floor normally will require extra bracing to make it solid and not flex from walking on it or furniture weight.
- Q:how many bags of 94lb portland cement make a cu yd using a 3:2:1 gravel:sand:cement ratio?
- A 94 pound bag of Portland cement is about one cubic foot. If you do volume:volume:volume you would add about 5 more cubic feet of material with your recipe. (6 cubic feet total) A cubic yard is 3' x 3' x 3' or 27 cubic feet. Is the material Pre-mix ready-to-use concrete? If so then about 27 - 30 bags. If it is cement, then your best bet would be to make 6 times the recipe listed above, therefore 6 bags. Should give you a total of 30 cubic feet. is is ALWAYS good to make too much that too little. Make stepping stones with the leftover.
