Specifications

AR Fiberglass Mat is an engineered AR-stem designed for use in the reinforcement of very thin layer (5-25 mm). It may b

AR Fiberglass Mat has a high elastic modulus and tensile strength, making them ideal as an effective reinforcement for cement matrices. They will not rot or corrode, and are unaffected by UV radiation, making them suitable for use with minimal cover.

AR Fiberglass Matis available in a range of nominal weight: Standard is 150 G/M2. It is produced by chopping Huierjie AR-rovings into 20-50mm strands and forming into a mat with a suitable binder. The mat has an open construction to permit penetration by cement mortar. The engineered binder, which dissolves with water further, assists incorporation into a cement matrix.

AR Fiberglass Matmay be used as a positioned reinforcement flooring systems.

Q: ok, can the mixture of sperm and female ejaculate cause you to get stuck if no cleaned up for hours?: well there isn't any way to be delicate about this you may just become a little crusty is all but no you wont make cement

Q: I live in an older house that has cement floors and they sweat bad .Is there anything I can do to make them stop sweating?: Maybe an epoxy coating, if you can get it to stick on the wet concrete. Otherwise, consider a plastic vapor barrier, with foam pad and a floating floor above. Building codes now require a plastic vapor barrier underneath concrete slabs to prevent this problem. They didn't know to do this back then, that's why your old concrete slab is sweating. It actually lets a lot of moisture into your house, and I think it makes the floor cold in winter, too.

Q: Is it gypsum ?: No it is: Tricalcium Silicate (C3S) C3S is the most abundant mineral in portland cement, occupying 40–70 wt% of the cement, and it is also the most important. The hydration of C3S gives cement paste most of its strength, particularly at early times. Pure C3S can form with three different crystal structures. At temperatures below 980?C the equilibrium structure is triclinic. At temperatures between 980?C – 1070?C the structure is monoclinic, and above 1070?C it is rhombohedral. In addition, the triclinic and monoclinic structures each have three polymorphs, so there are a total of seven possible structures. However, all of these structures are rather similar and there are no significant differences in the reactivity. The most important feature of the structure is an awkward and asymmetric packing of the calcium and oxygen ions that leaves large “holes” in the crystal lattice. Essentially, the ions do not fit together very well, causing the crystal structure to have a high internal energy. As a result, C3S is highly reactive. The C3S that forms in a cement clinker contains about 3-4% of oxides other than CaO and SiO2. Strictly speaking, this mineral should therefore be called alite rather than C3S. However, as discussed in Section 3.2, we will avoid using mineral names in this monograph. In a typical clinker the C3S would contain about 1 wt% each of MgO, Al2O3, and Fe2O3, along with much smaller amounts of Na2O, K2O, P2O5, and SO3 [2]. These amounts can vary considerably with the composition of the raw materials used to make the cement, however. Of the three major impurities, Mg and Fe replace Ca, while Al replaces Si. One effect of the impurities is to “stabilize” the monoclinic structure, meaning that the structural transformation from monoclinic to triclinic that would normally occur on cooling is prevented. Most cements thus contain one of the monoclinic polymorphs of C3S.

Q: So, long story short, i broke a nice glass bowl and tried to find super glue, all i found was quot;vinyl cementquot; so i looked it up and it said the fumes are flammable. so is it ok so smoke out of it after it completely dries?: Define 'smoke out of.' I'm not sure what the auto-ignition temperature of the vinyl cement you're using is, there's probably an MSDS sheet on it available from the manufacturer. Depending on how much you're using, I'd be more worried about breaking down the cement with heat and inhaling any off-gassing/fumes. But its probably fine. EDIT: Also, vinyl cement probably won't work. The vinyl cements I'm familiar with use a chemical reaction with the vinyl to create heat and fuse/melt the two pieces of vinyl together. Since glass isn't vinyl, it probably won't hold (for very long, at least).

Q: Was there concrete/cement in the 1880s-1890s?: Uh oh. She forgot the Romans in her History of concrete. Their concrete work is still standing. :) But I liked the story. I know you asked about the 1800's, but if you are also interested in Roman (cementitious) concrete history, here's an interesting site from the University of Santa Barbara: id-archserve.ucsb.edu/arthistory/...

Q: Eucalyptus leaves were left on the front porch. It rained. Evidently, they are treated with some type of coloring agent and it dripped from the leaves to the porch cement leaving a bluish stain. The tint washed right off my hands, but not so with the cement which absorbed it like an easter egg.I've tried soap and water -- no good.Krud Kleaner with a wire brush -- faded it a little.OxyClean with a toothbrush -- faded it a little more.But, the stain is still there and very visible. Is there anything that will get it out? Bleach, maybe...vinegar ???Help!Thanks.: use outdoor bleach instead of regular household bleach. should clear the stain right up

Q: carpet padding on a cement floor whats good?: Cement floors absorb water from the earth below and if not done properly will result in a soaked carpet and padding (which effectively becomes a sponge). You need to waterproof the cement floor. There is a product that is skimmed/troweled onto the floor to waterproof it, but do not know the manufacturer or product name. (An alternative would be to put a vapor barrier down before the padding). You also need to use the right type of padding on concrete, or use adhesive to adhere your padding or else the carpet will need stretched again before too long. Also, the tack strip should be glued against the walls instead of nailed in, unlike on a wood floor where nails would be used. Tack strips with masonry nails ar OK (just don't use the nail ones for a wood sub-floor).

Q: please tell me the order of increasing strength of cement mixtures1)cement mixed with river sand 2)cement with lime3)cement with pitsand4)cement with rice huski think order is 2 gt; 3gt;4gt;1 (strength)i am not sure.please tell me the correct answer along with explanation.: we assume the cement (Portland cement) is of the correct ratio. we also assume we are talking about compressive strenght when we have just enough cement to fill the spaces between the rock we have reached the maximum strength. number 2. is no good as it reacts with the cement mixture number 4. allows for compression and cracking of the cement. number 3. .....pits i dont know what is pits number 1. is the same as rock ......the best here so .... the order my guess ....... 2,4,1

Q: i recently removed the tilling from my basement floor and now my basement is just plain cement flooring. What are the steps i need to take to tile over it?: If you removed a ceramic tile either bu sure to scrape /break off existing thinset to get a smooth surface. Or you can use a self leveling mortar to smooth it out. You need a smooth clean surface to start out with. Then you can tile it.

Q: know the cement but I want to know the exact definition in engineering view.?: Cement generally is a powder which when mix with water, chemically bonds with it and forms a paste and eventually hardens. Cement bonds aggregates (sand and gravel) to form concrete. When a steel is used to reinforce concrete, this is called reinforced concrete. Cement is used in plastering walls, filling hollow blocks, tile setting, floor screeding and others. Cement is always part of everyday life in construction from foundation to finishing.
