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: hellow I gutted my bathroom all the wall board and I put up cement backerboard and want to know what I can use on the seams I have the fiberglass mesh tape , Joint compound is for wall board grout is for tile . Cement ? plaster ? I want it waterproof hydrolic cement ?Any help With this I would really appreciate.I'am an electrician not a wall trade and i want it to be right , from the jump. Thanks g, Singh
- Remember that when you tile to use 100% silicone in the corners and along the bottom edge before grouting. Let it cure a couple days. This will prevent any grout from getting into those joints. I also used red guard on the seams and joints of the backer board.
- Q: Well... I want a basketball hoop up. We have a hoop and pole, but we need cement. Does anyone know approximately how much it costs per square foot? Or any cost they know of that they might have paid for a cement pouring so I can estimate?
- Calculate the area and volume of the court you desire. Keep all units of measure the same. Assume the following Area = length x width volume = length x thickness I cubic yard of cement = 27 cubic feet =(3' x 3' x 3') Example: 10' x 10' court that is 3 thick area = 10' x 10' = 100 sq ft. Volume = 100 sq ft. x 3/(12'/ft)= 100sq ft x .25'= 25 cubic feet. 25 cubic feet = 25ft^3 / 27ft^3 = .92 cubic yards of concrete. Figure about $55 to $75 per cubic yard of cement. Your court would cost about $50 to $69 for the concrete. Or in other words about $0.50 to $0.69 per square foot. This does not include labor. Then consider other materials such as re-mesh or re-bar to add strength to the concrete.
- Q: 13 inch diameter solid concrete stone - yes it will be heavy = approximately 90-95lbs.
- If you are using only Portland cement and water in the 1:4 ratio for the reaction to complete properly, you will need 80% cement by volume. Very few applications use pure Portland Cement however. V(sphere) = (4/3)(pi)(r^3) r = d/2 = 6.5in V = (4/3)(3.14)(6.5^3) = 1150in^3 1150in^3(0.80) = 920in^3 of Portland cement One sack of Portland cement (94 pounds) is approximately 1 cubic foot which is 1728in^3 920/1728 = 0.53 or about 1/2 sack or 47 pounds of Portland cement. If you are using the traditional 1 : 2 : 3 mix of cement:sand:gravel, you use 1/6 cement, or 47/6 ~ 8 pounds. At 80% due to 1:4 water mix = 8(0.80) = 6.4 pounds. At 133 lbs/ft^3 or 0.077 lb/in^3, 1150in^3 weighs: 1150(0.077) ~ 89 lbs Your answer is then either 47 pounds of pure Portland Cement or 6.4 pounds as part of a 1:2:3 dry mix combined with water at a rate of 1:4 (the latter is the practical answer). 6.4/94 ~ 1/15 sack. Remember that these figures are based on general rules of thumb and do not take into account any particular service requirement. - .--
- Q: This pipe is located almost underground. Due to the blockage the water from the terrace instead flowing to the underground main pipe flows out at the first floor opening in the balcony. The pipe is a direct pipe from the terrace to the ground with a break at the balcony, but due to the blockage at the end overflowed water fills the balcony. Hence it starts entering the rooms at the first floor. Our house is made of bricks and cement, it is situated in Pakistan. Problems of overflowing increase durng the rain( Monsoon) season.
- Acid will 'eat' cement, but not PVC. it takes time though. You might need to power flush the sand that will be left behind.
- Q: how to make cement,,,,,,?
- 1. Drive to home improvement store 2. Ask employee Where is the cement 3. Proceed to aisle with cement 4. Purchase bag of cement 5. Return home and prepare cement per instructions on the bag
- Q: I want to do this trick, but it involves putting rubber cement on your skin. I'm not sure that it is safe. I'm thinking of buying Elmer's rubber cement if it is safe. Also, if it is safe, will it stick? And how do you get it off?Thanks!
- I don t know If its safe
- Q: given only the volume of the project...
- There are a couple of rules of thumb for determining quantities required for a project. The old rule is a ratio of 1:3:4 Cement to Fine Aggregate (sand) to Coarse Aggregate. But this describes the mix proportions and since the cement and fine aggregate will disappear into the voids in the coarse aggregate another ratio is recommended. A common approach is by the bag mix ratio. A 6 or 7 bag mix will be quoted. These are ratios of numbers of regular bags of cement per cubic yard of mix. A 6 bag mix will normally require 6 bags of cement 15 cubic feet of fine aggregate and 20 cubic feet of coarse aggregate. A 7 bag mix will require 15 cubic feet of fine and 21 cubic feet of coarse aggregate. Why don't they add up to 27? Welcome to the wonderful world of concrete.
- Q: Is it safe to clog on my basement floor thats made of concrete? I just got new clogging shoes and each time I stop, I feel a few layers of the taps peeling. Is this because they are new or because they are being used on this type of floor?
- the type of floor you step on slowly scrapes the bottom of your shoes as with any other shoes or slippers, but cement does make it worst due the the uneven roughly layer it has. hope that answers your question!
- Q: I know they grab onto wood and trellis' but, do they need some kind of support to cover a cement wall?
- They wll grow with little support. I have seen them climb the side of a stucco house
- Q: It was fine for the first 4 winters and then we had a real hard freeze that lasted for a few weeks, the fish survived but the pond leaks now. I tried draining it and patching but it didn't hold. Is there a simple solution?
- Dap makes Liquid Cement Crack Filler. It is an epoxy that actually glues cement back together. It comes in an easy to use quart squirt bottle. I used it when our fountain froze and chunks of cement broke off. Two winters have gone by, and we still have a water tight repair. You can find it at a Home Center like Lowes or Home Depot.
