Ⅰ . Product Description:
NZY-SR retarded type water reducer is composed of high performance and high efficiency water reducer and retarded components, slump retention components, as well as other functional components, with high performance of water reducing, slow slump loss and Concrete hydration temperature rise.
NZY-SR can effectively inhibit the concrete early hydration and without affect the later strength, is ideal concrete admixture for high performance concrete, mass concrete and long-distance transport concrete products.
NZY-SR retarded type water reducer has both liquid and solid package.
Ⅱ. Main technical features
(1) A kind of polyhydroxy organic compound, non-toxic, odorless, non-flammable, and free steel-corrosion effect.
(2) Extend setting time, reduce mixing water (5%-30% water saving).
(3) Extend induction period of cement hydration, slow down hydration rate, delay cement hydration exothermic process.
(4) Improve workability, easy to pour and vibrate.
(5) Increase strength, reduce cement content.

Ⅲ. Applications
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: what does an additive meanor how do additives affect plant growth
- An additive is something extra. For instance, fluoride is a common additive to water.can affect plant growth, by giving extra things that the plants either may need in order to grow (aiding plant growth), or that can act as poison for the plants (inhibiting plant growth). For instance, adding salt to water, making salt water, can kill certain grasses - but can aid the growth of other grasses (depending on what salt was added).
- Q: how to solve HELP?????Thanks
- are you serious mate? your a dead set bloody tool! If your car is naturally aspirated then DONT put an intercooler on your car! There is absalouly no point in doing it and its also restricting airflow into your radiator. And putting an air filter on one end of the intercooler is just gay. If you want a form of cold air intake then just get a pod filter and run it to your wheel well area and feed a cold air pipe to it. If your just after it because it looks cool then you sir are a TOOL
- Q: Find a number which is 9 less than twice the additive inverse.?
- Get it very hot. Almost 2000 degrees F.
- Q: I have a 1983 Series 3 Land rover (Lightweight), should it run on unleaded or does it need the additive?
- it will run on un leaded .may need small adjustment to ignition timing?,
- Q: Hi, has anyone used Lucas oil stabilizer in there car or truck? If so what for and what differences did you hear/feel? Thanx
- The oil viscosity determines how thick or thin it is. There is little difference between 5w30 and 10w30, so it should be fine. The first number refers to cold start ability so if you drive in below zero temperatures the 10w30 may be a little worse. Otherwise I wouldn't worry. All motor oil should also be API certified so that it meets certain quality standards.
- Q: Find the opposite, or additive inverse, of 3/4 ???
- I believe that the additive inverse is just the negative of the number so it would be -3/4
- Q: My car just came back from the mechanic and he told me to keep an eye on the transmission because sometimes when you set the car to reverse it takes awhile before it kicks in. He said it could be that it is sticking and needs more additives? But then we got distracted and I never got a chance to ask how the heck do I find out? By the way, my car was in for a different problem and I had specifically told him I only had money to fix that so that is why he didnt look further into the transmission thing.So anyway, here are a couple of questions:what is additives and how do i know if i need them?while we‘re at it, how do I check my transmission fluid? (just in case my mechanic didn‘t)if you have any other suggestions as to what this problem might be and how I can fix it, Id love to hear itIf it matters, I drive an 03 Dodge Intrepid that has about 80k.Thanks!
- Call two Dodge dealers' service depts [always get at least a 2nd opinion]and ask abt additives, they prob dont recommend em. Pull the trans dipstick and see if it has stamped on it how to check the fluid, ie, engine at operating temp, in Neutral, on level surface, etc. ask the dealers.
- Q: What are the primary and secondary additive and subtractive colours?
- Additive: Red, Green, Blue (you add them to black to make a full range of colors) Subtractive: Cyan, Magenta, Yellow (you subtract them from white to make a full range of colors, except for black. Your printer is going to need a cartridge of black ink too)
- Q: how do u find it?
- The additive inverse of a number N is the element which when added to N produces the unity element for addition (zero). So... N and -N are additive inverses of each other. To get the additive inverse of a number, multiply the number by -1. More specific examples of additive inverses: (-5, 5), (3, -3), (1.4, -1.4)
- Q: Andy fly fuel additives how? I heard that China is the only high-end additive brand who used?
- It seems, try chanting.
