AR-Glass fiber chopped strand
1) Pre-mixed chopped strand
It has excellent properties with alkali redsistance,stiffness,bundle-state,ageing-proof .Mixed 20 minutes in cement at 50rpm,can still keep good bundle state,will not dispersed to filaments.
It is a high integrity AR glass fibre chopped strand designed for use in the reinforcement of concrete ,renders and mortars.It may be added to conventional mixes either on site or by preblending with other dry mix components .The low-tex strand permits efficient reinforce ment at low dosages . They are particularly suited to the modification of standard concrete mixes for floor screeds and slabs , and for the preparation of prebagged mixes of special mortars and renders.
2) Water-dispersed chopped strand
Applied with water-dispersed size,the strand will disperse well to filaments in water in10 seconds , and also disperse fast,appliance amount less,enlarge strength.
It is typically used at a low level of addition to preventcracking & improve the performance of ready mix concrete , floor screeds , renders or other special mortar mixes . It can be used for surface crack - proof of GRC products.

- Q:pls any one give safety tips for cement dust allergy ?
- Your father could already be suffering from mild bronchitis and if he continues to inhale the powders from cement could cause emphysema to acute lung disease. A tiny dust that may enter our air sacs can be very devastating and can create problems with our breathing comfort. It can also affect his kidneys and bloodstream since pure oxygen from the air we breath are lessened. If he can't wear face masks then your father should provide a good ventilating fan as exhaust to drive out the cement dust inside the room or from the place he works. Remember that an ounce of prevention is better than a pound of cure.
- Q:Could desert soil be used to make marine cement?
- Caliche is a hardened desert soil (rock) that is typically near the surface. I would think that you would end up digging a lot of desert to get much carbonates. There would be a large amount of heavy equipment use, lots of dust, and lots of lost habitat. Typically cement is produced by exposures of limestone that are ground down and converted to cement. I would think this would generally be a more economical and more environmentally friendly option. Since you apparently have a chemistry background, you may already know this, but cement is generally made by taking calcite or dolomite and heating it up to create lime / cement. This has been done since the Roman Empire. I have never heard of bubbling CO2 in calcium and magnesium carbonates. Are you suggesting that bubbling CO2 in ocean water will precipitate calcite? I think it would probably have the opposite effect and create more acidity which would tend to dissolve carbonates. Note: Ocean water is very basic. It is far from acidic and will almost certainly never become acidic. If you add a base to the desert soil, form a pile on the ocean floor, and bubble CO2 into it, you might precipitate some CO2 if the water is warm enough IMO. It would probably make more sense in most instances to simply use regular cement which is designed to form a very solid and strong structure. Carbonates will precipitate out of sea water in warm shallow water. Some of the beaches of the Bahamas are formed from precipitated carbonates called oolites.
- Q:What is Cement Asbestos?
- You are thinking of a siding panel that was manufactured back before the 70s? Cement and asbestos panels, maybe 1 foot by 2 foot. There are replacements now for this siding that contain no asbestos. A very old siding, and no, you would know the difference between concrete and this siding.
- Q:No tile how to paint cement board in shower?
- a high gloss high quality concrete paint, the high gloss will make it easier to clean, you need to make sure that it is completely dry before you shower in it and that the concrete is completely dry before you paint it or you will get bubbles and the paint will peel. I would use a paintable silicone for the seams.
- Q:what means by special cement ? Example ? website ?
- *Special Cements: It is used for a special application and are having special additives like some minerals. Example: 1.Rapid-setting High-strength Sulphoaluminate Cement, 2.Aluminate Cement, 3.White Cement 4.Special Inorganic Cements. 5.Anti acid cement (acid resistant cement) *** Polymethylmethacrylate (PMMA), has been used to reconstruct bone during surgery for at least 20 years.
- Q:What would the cost be for this much cement?
- Guitar George has it right. You need concrete (some people call it cement but that is technically not correct) It needs to be at least 3 1/2 inches, maybe 4 $100 cubic yard for concrete delivered. Does not include labor to place and finish. You will also need formwork and rebar.
- Q:1 cement bag??
- The actual cement required for concrete is affected by the choice of the maximum coarse aggregate size. As the maximum coarse aggregate size is decreased the cement content must increase to provide the required quantity of cement paste to coat all of the aggregate particles. Assume that the proportions will be made based on one part being a cubic foot (this is convenient since a 94 lb. bag of cement is 1 cubic foot of bulk material). For a 3/4 maximum coarse aggregate, the mixture would be 1 part portland cement, 2 1/2 parts sand, 2 1/2 parts coarse aggregate, and 1/2 part water. The sum of the parts is 6 ½. In general the final volume of concrete produced will be approximately 2/3 of the sum of all the volumes included in the mixture. Therefore the approximate volume of this concrete mixture is 4.3 cubic feet. If you adjust the above mixture based on a 80 lb. bag of cement, then you will produce 3.7 cu. ft. per bag approximately. If you are talking about an 80 lb. bag of ready mix (sand garvel are already mixed in the bag), then it would be 0.60 cu.ft. per bag.
- Q:how is cement made? and what is the chemical formula?
- A cement is a binder, a substance that sets and hardens independently, and can bind other materials together. it was made from crushed rock with burnt lime as binder. Cement (as in Portland type cements) is made by heating limestone to 1450 degrees C, then grinding the result into fine powder and adding a small amount of clay. When mixed with sand, stones, or other aggregates, the result is concrete. Cement hardens by hydration, absorption of water, and not by drying. Chemical Formula for cement i think its 3CaO SiO2 Go to this link... this may help you to find you a better answer elearning.vtu.ac.in/Programme%2016/ENotes/ConcreteTechnology/Unit1-RVR/Unit1-L2-RVR.pdf
- Q:can you put hydraulic cement over a painted cracking cement wall?
- That sounds more time consuming than just scraping off the peeling paint..... Here's 1 problem w/your approach, latex paint dries so fast that it actually creates a vacuum effect in doing so, which means that as it dries it'll pull off the surface anything that's not firmly attached, which is why prep work's so important to longevity. You won't immediately notice this happening, but w/the passage of time you'll be back to the peeling wall in spades. I've never heard of skim-coating w/hydraulic cement, but I've done plenty of patching plaster walls w/plaster of paris, what immediately comes to mind are the inherent problems w/working in a medium that sets up so quickly, I can't imagine how you'd get a whole wall covered looking even satisfactory (but I'm pretty picky, I figure when people are paying me I'm obliged to do a better job than they could've) w/out going insane in the process. I learned the trick to plaster, but I don't know the chemistry of hydraulic cement well enough to find a retardant for it. Anyways, I know prep-work sucks, but often it's just easiest to do it get it over with (start w/a stiff putty knife, by the way) rather than inventing a new process having to deal w/a long string of learning curves as you go. The first question that came to mind w/your question is have you ever skim-coated anything before so that you'd have even a vague idea of what you're getting yourself into potentially, but if you must create, than by all means go forth!
- Q:Best Stain for Cement Patio?
- you don't stain cement you paint it!! that is why you are having to redo it every year. cement does not absorb things paint is thicker and will stick to the cement.
