Ⅲ. Applications of NZY-SR RETARDER
NZY-SR retarder is used in reinforced concrete, prestressed concrete, mass concrete, pump concrete, road concrete, and waterproof concrete construction projects which require extension of setting time.
NZY-SR retarder is suit for concrete construction in summer or hot weather.
NZY-SR retarder can be used in slip-form concrete construction.
NZY-SR retarder can be used as supplementary materials for produce or remix other concrete admixtures.
Ⅳ. Packaging, transport and storage
(1) Powder retarder is available in 25±0.25kg film-lined bags. Liquid t retarder is available in sealed 200kg or 1000kg bucket. Other special package can also be available according to prior consultation.
(2) Special measures should be taken to ensure entire package. Keep waterproof during transportation.
(3) Dry and well ventilated warehouse is needed for storage. Quality guarantee of retarder is two years under normal conditions. If storage has surpassed the time, test must be done to confirm the validity.
Ⅴ. Health and safety
(1) Once splashed into eyes and skin, wash immediately with plenty of water and seek medical treatment.
(2) Inedible. When eating by mistake, drink sufficient water to urge to vomiting, and then go to hospital.
(3) No littering. Caution should be taken to protect environment.

- Q:Does anyone have a clue?
- 'Portland cement' is the name of the stuff you mix with sand and water, maybe some gravel, to make concrete. The structure is concrete, the ingredient is cement.
- Q:My backyard at home is completely cement. There is no ground to grow a garden. Any suggestions or ideas on how I can have my own garden and grow my own plants ?Maybe even something that won't corrode the cement over time ?
- Large pots and hanging planters will do the trick.
- Q:the types cement made all over world.the good cement use for building construction,cement quantities to abtain all differant kind of building works.any good web site address.
- types of cement varry from a place to the other , they are basically 12 . The most common is the Ordinary Portland Cement
- Q:Omg, pease help me remove this cement from my teeth, You see I have an appointment July 15th but I CANT wait that long and plus Im going to London in 2 days so I cant attend the appointment. So is there anyway at all I can remove this dental cement from my back tooth. There is like a little roug spot of it that bothers my touunge SOOOOOOOOOOOOOOOO much. Please help.
- Did you have a crown (cap) on that tooth? dental cement is not hard to remove, id advice to go to Walmart or any store and buy dental kit, use the sharp instrument that looks like a hook to scrape of the cement. Be carefull!! if you did have a temporary or permanent crown ont that tooth you should see your dentist so they can re cement it. You can loose a tooth if its uncovered.
- Q:I'm trying to go green and I have clay cat litter. I know when cat litter gets overly wet it can resemble cement. But can it be used for making cement? Not sure what the recipe for cement is. I thought it was clay.
- Are you suggesting to reduce/sanitize/recycle/reuse?
- Q:what is sound proof cement made out of?
- Cement isn't really sound proof. If someone said something like I was trapped in a sound proof cement chamber It means that the chamber was sound proof, not the cement it self.
- Q:Are they just two different terms for the same thing?
- Cement is the mixture used in producing the finished product of concrete. Kp
- Q:is duco cement good for crafts. I'm building a bridge and weight is going to be on it so if i use duco cement will the bridge be strong? the bridge has to hold 1,000 pounds at least and the pressure is going to be different on each beam.
- I would avoid cements as often as possible because they're not good for lungs and also won't be flexible when dry... and may not be as strong as you want for some situations. Not many glues would be good for a thousand pounds of weight, though of course that would depend a lot too on the exact structure of the bridge --some would require no glue at all. You also don't say what *kind of materials* you'll be using and various adhesives are better for different materials as well. I think you'll want to look into other things besides glues for holding 1000 lbs, but the strongest glues I know of would be the polyurethane glues like Gorilla Glue, etc, which is even used for concrete. GG has to be clamped or weighted while curing though since it will swell and extrude out at the beginning, but some of the later brands of polyurethane glue may do that less. I think you'd be better off asking this in an engineering or construction category than in the hobbies category ...there's probably something like that here at YA. HTH, Diane B.
- 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:BP is currently pumping great quantities of mud into the rupture in the Gulf and plan to dump cement in when the flow permits. Cement has to dry to be effective? So how does it dry under water and the pressures it will encounter at that depth.
- it doesn't dry; it sets - it's a chemical reaction; not simply evaporating its water content. Setting time depends on the exact chemical mix of the cement - unsurprisingly, fast-drying cement sets very quickly but is usually comparatively brittle, while slower formulations take longer but tend to be stronger. Considerable heat is given off during the setting process and the cement tends to expand, particularly if too much is added at once so that the heat in the middle can't dissipate quickly enough - this is another reason why slow-setting is preferred in many situations. Setting is also speeded up by spraying with water which not only aids the chemical reaction but also helps in cooling. Under the sea the water would actually assist in the setting process. The main problem is that it will be subjected to the pressure of the escaping oil while setting which will reduce its strength - this is probably why they're also pumping mud into the hole - this will partially clog up the hole and reduce the pressure and so give the cement a better chance of working.
