NZY-SR RETARDER
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 of NZY-SR RETARDER
(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 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: I want to determine the percentage of Chloride present in any cement. Then can any one tell mePl., the standard method of determination of percentage of chloride in any type of cement.
- figure out what the cement is made of in terms of chemical formula. use Cl5S2 as a rhetorical example *by the way, thats way off, divide the number of chlorine by the the total number of atoms in the formula. so in the example, its 5/ (5+2), which is about 0.714, so in the example there is 71.4% chlorine/ chloride
- Q: My parents had a new cement driveway put down last summer, and accidentally used a non-safe-for-cement salt, and now it is flaking in small areas. Can this damaged be repaired by some kind of patch or filler compound - or is the damage permanent.
- There are salts that do not damage concrete or cement. I would go to Home Depot and ask one of the associates. They should be able to guide you. You also should get a decent response on Google.
- Q: What is cement?
- Calcium Oxide, Made by Roasting Limestone, , When Mixed with water and Air, It goes back to Calcium Carbonate, (limestone) to glue sand and gravel together to make concrete
- Q: I put it over ice instead of salt and now it's still on the cement in hard clumps.
- I don't think you can 'dissolve' it -- you're going to have to scrape it off and remove it -- even if that means wetting it again to make it pliable enough to scrape. What's left behind after that will pretty much have to wear off -- That wasn't a good alternative to salt I'm afraid! The clumping litter acts like cement; the only difference is it gets mushy again every time it gets overly wet! Yuck!
- Q: Is there any standard formula to calculate the 1 cubic meter cement for each mix?
- what is Loose Cement 1440 Kg/ cubic meter Loose Sand 1525 Kg /cubic meter aggregate avarage 1500 Kg / cubic meter
- Q: Hey. Could anyone please tell me if it would work to mix fast curing cement with Portland cement so it would cure faster than normal. Because with weather getting colder its really hard to cure cement properly, but since I'm working on tight budget it is really expensive to use only fast curing cement.Thank you
- Hi, Yes you can add a rapid set cement to your regular cement to make it go off quicker. I would recommend using an accelerator within the mix rather than using a rapid set. I would also (depending on what you are doing) use the correct insulation once you have poured the concrete - so use a thermal blanket, or straw and a plastic sheet. Keep it protected from the wind/water/elements for as long as you can - the longer the concrete has to set the stronger it becomes. As a word of warning however, if you put too much accelerator in or cure the concrete too fast, you will get a weaker concrete, that at worst will crack and crumble, so always consult the manufacturers instructions. Concrete setting causes an exothermic reaction meaning if you cover it properly it'll keep itself warm. Remember that if its below 5 degrees (Celsius) you shouldn't pour concrete! Hope that helps!
- Q: Is it better to sink fence posts in cement or geavel?I keep getting mixed answers on this. To me filling the hole with gravel will not be as sturdy as cementing the posts in. Which is better in the long run????
- Depends what it is you're holding up. The best method is to pour your concrete footer and set a J bolt in the wet cement. When it hardens, set your posts using a Simpson ABU44 for 4'x4 posts, or an ABU66 for 6x6 posts. These construction anchors are available at any lumber yard or home store. Setting the posts in the ground will make them rot, even if they're treated. The anchors will keep them up off the ground.
- Q: more accurately how should one space floor boards on a cement slab subfloor? every 4quot;...6quot; also any recommendations on what type of plywood/board to use? should i use insulation or just concrete board?

- Q: I'd like to use plastic cement as a mortar (typical lime-free brick and stone mortar) to secure rocks in my new pond. The pond quot;shellquot; is 4 to 6 inch reinforced concrete with a fish safe epoxy sealant. The rocks would line the wall of the pond shell.
- White Portland cement is lower alkalinity than regular Portland. You can get it at most brickyard and stucco suppliers. Plastic cement may have a different expansion/contraction coefficient from concrete and mortar. It is very likely to pop off as temperatures change in the pond if that coefficient is too different.
- Q: 2011 building materials reinforced concrete price movements, I now cover the next year or cover? The
- General winter is the golden season of the building, no rain, the weather is not too cold (not in the north), so the building materials are generally started up in winter, recently this year have this phenomenon
