Instructions of High Quality Rigid Polymer Fiber:
The High Quality Rigid Polymer Fiber uses polypropylene as its raw material. It is a substitute for steel fiber in the reinforcement of cement concrete and crack resistant. Compared with steel fiber, it has the advantage of easy dispersing and blending, no damage to the mixing equipments, high break strength, strong bondability, etc.
Technical Data of High Quality Rigid Polymer Fiber:
Equivalent Dia(mm): Ø 0.3±0.05
Strand Length(mm): 20,30,54
Density(g/cm 3 ): 0.91
Elastic Modulus (MPa): >3500
Shape: bundle-like and twisted
Tensile strength(%): 8-15
Break Strength(MPa): ≥ 350
Resistance to acid,alkali: strong
Features of High Quality Rigid Polymer Fiber:
1. Ration design of the fiber concrete
The recommended volume for concrete is more than 2.7kg /m 3 ( volume ratio is 0.3% ) , reinforcement adding amount is 5.5kg , Compared with adding 47kg of steel fiber, 5.4kg polymer fiber has the same volume ratio to the concrete.
2. length
50mm for common crack-resistant requirement.
3. Matching Ratio
Usually, it is no need to change the matching ratio of the concrete.
Considering the requirement of fissure-resistant, the polymer fiber is recommend to combine with the polypropylene fiber mesh with the volume ratio of 1:1( 0.9kg fiber-mesh to per sqm of cement concrete).
4. Mixer Adoption
Double-axle horizontal compelling mixer is priority.
5. Mixing process
Crushed stones, fibers and sands are put into the mixer in succession. After stirring for two minutes, fiber will fully disperse and then add cement, water and stir normally. The addition materials also can be put into as common concrete, but the stirring time should be properly prolonged to make fiber completed mixed.
- Q:the concept is very difficult to understand wat is happening in the hydration of cement....its difficult catch up the points
- To simplify and expand upon what the other answer said: Concrete becoming a solid isn't a matter of the mixture simply drying out. It is a chemical reaction between the water and the cement. The chemical reaction gives off heat during the process. We keep adding water to concrete during the curing process so that there is enough water in the mixture to completely react all of the cement, rather than allowing the heat to cause some of the water to evaporate before it gets a chance to react. The heat of hydration is the amount of energy given off (as heat) during the reaction.
- Q:I have a walk-in shower (no door) and was planning on using cement board for the wall floor. Do i have to use a vapour barrier behind the cement board on the would frame? If so, what kind? Simply lay the tile on the board (wall floor) with thinset? What kind of thinset? Any help would be appreciated! Thx
- More info is needed. What is on the floor of the shower now? A vapor barrier is needed for and insulated exterior wall. I use 15lb felt but 6mm poly can be used also. Insulation-vapor barrier-cement board with edges and corners taped with cement board fiberglass tape and thinset. Versabond modified thinset.
- Q:Wat are the differences in Concrete,Cement,and Moder?
- cement is the binder in both concrete and mortar...sand, gravel, cement and water = concrete sand ,cement, lime and water = mortar
- Q:We have an odd shaped living room and the way we have it arranged our couch is sitting in front of the woodstove. It has not been a problem since it has been warm out and we have not been using the stove, but now that fall weather is here we are getting to the point that we are going to have to use it. Our couch sits about 2 feet in front of the stove with the back of the couch facing the stove, its enough room for a person to walk between the couch and stove without touching the stove. I need to know if we can attach a piece of cement board that has ceramic tile on it to the back of our couch to make it safe from getting too hot and causing a fire. Thanks.
- To answer your question, yes, it would be okay to install a cement particle board to the back of your sofa, to provide a barrier between the stove and the sofa. If you choose to go with this option, purchase the ones with higher fire resistance and install the wall backing from the bottom of the couch, to a height high enough to protect people's heads. But. if there is enough space, it would be better to move the couch further from the stove instead. In fact, if you can move some stuff around, it would be much better to shape your furniture like a U, with the open end facing the stove. Just as you would fix it around a fireplace. Because it isn't just the couch you need to protect, it is also the people sitting on it. Flying embers could scorch hair and clothing as well. And if you have small kids, regardless of what you tell them, they will once in a while forget and will pass through the space between the stove and the couch. With a U-shape, there is a better chance that they will pass between furniture, as opposed to between furniture and stove.
- Q:if it is is it renewable or nonrenewable?

- Q:The molars are the ones that hurt, my braces dont hurt as much now. I can't bite down on anything because of the ketac cement they placed on my rigth and left top molar. Is this normal, will the pain ever go away so that I can chew my food. I can't chew on anything. I got my braces on a Friday and it's Tuesday and the cement still hurts.
- Hi, I have braces too, but not molar cement. I would take some aspirin or other pain reliever. Wait about three days and if it still hurts, you should contact your orthodontist and ask him if this is normal.
- Q:Is cement heavier when it's wet or when it's dry?Say, i have enough cement to make one cement block, would it be heavier when it's wet or when it dries into the block. Or would it weigh the same amount?(just wondering, sorry if the question seems kind of dumb)
- The wet would be heavier because when the water evaporated,you would lose the weight of the water. It would have nothing to do with, if dry cement was heavier than water or visa versa. Oh yeah, a cubic fot of water weighs more than 10 pounds, water weighs 8 pounds per gallon. A cubic foot of water is 7.48 gallons and weighs 59.84 pounds.
- Q:I think we have been already taught how this goes, butIf you mix water and cement, and you record the mass while it's still wet, then if it dries, will you also get the same mass? if not, much percent do you think will be lost?
- The problems with cement is that it's a very Thirsty molecule. Could be all the water remains in the concrete. Concrete doesn't harden because it loses it's water - it hardens because of a chemical change (it's hot). Portland cement can harden under water - and the Romans understood this. Some of their bridges are still in use. Then the idea was lost until the end of the 18th century, I think.
- Q:the question reqires a chemist's mind to give answer.what is the ion level and electron level chemical reaction taking place when we put cement-sand paste on a brick wall.please answer for the understanding of a layman?
- I think you are missing a few of the ingredients in the cement mix and their function. Cement is not made up of just powdered rocks and water.
- Q:doing a red brick fireplace at home.what sand/cemnt ratio should i use?
- 7 t0 9 full shovels of sand half bag of cement one shovel full of portland dry mix then add water an mix thoughrly
