Product Description:


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.

. 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 truly believe that the only way to cement a romantic relationship with a man is by having a baby?
I think its Absolutely sick when a woman decides to get pregnant on purpose just so the man has to stick around, and usually, this blows up big time in these woman's cases. And how selfish to bring a child into the world for that reason? A romantic relationship and a relationship with a man is two very different things, my husband and I would be lying if we said we were romantics, its a small part of our relationship and I dont get the correlation between a romantic relationship and having a child, I just dont get that statement at all. Many couples decide to have a child because they want a family, it isn't to prove there love to themselves (or at least shouldn't be) or to others, its a choice in their relationship
Q:What dissolves clumping cat litter on cement?
it is made of clay. about nothing will dissolve it. scrape it off with a shovel
Q:Will watering new cement help it to cure?
Avoid building on it for at least 4 to 10 days, depending on thickness. Concrete in industrial applications is deemed to have reached a high percentage of its final strength after 28 days, which is when it is tested. In reality, concrete continues to cure and harden for years!
Q:Cement and its early uses and terms?
Cement used in construction is characterized as hydraulic or non-hydraulic.It is uncertain where it was first discovered that a combination of hydrated non-hydraulic lime and a pozzolan produces a hydraulic mixture (see also: Pozzolanic reaction), but concrete made from such mixtures was first used on a large scale by Roman engineers.They used both natural pozzolans (trass or pumice) and artificial pozzolans (ground brick or pottery) in these concretes.
Q:What are the building materials used in the construction of agricultural infrastructure?
Can be divided into structural materials, decorative materials and some special materials
Q:What gets paint of cement?
That is difficult because the paint seeps down into the little crevices of cement.. You can do one of the following 1) apply a paint remover and follow the instructions.. the paint will then crumble a little.. use a wire brush to brush as much as you can to get off as much as you can. 2) Try using an acid... the acid that is used for swimming pools and apply that and using a wire brush to attempt to get the rest of it off... TAKE caution, however, when using the acid.. goggles, boots or something similar
Q:can temporary dental cement help put my split teeth together again..?
Temporary cement won't unfortunately help that much. You can resin filling placed to bond the pieces together. However, the ultimate restorability of the tooth depends on how far down the crack extends.
Q:Whats the best way to remove Backsplash cement board without damaging Drywall!?
Since it sounds like the cement board is atop the dry wall and you say the tiles are removed. find all the screws or nails and remove them. If nailed , a cats claw will work and if screwed in, you can use a drill with a phillips bit in and remove. Hard because you ll have to find the nails or the screws will be filled with what ever glue they used , but it can be done. Any questions you can e mail me through my avatar and check my qualifications there. GL
Q:How do I stop sweating cement floors?
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:what is the importance of cement industiries?
Below are some reasons why cement industries are important. Cement industries produce Portland cement which is a prime ingredient of concrete for buildings, bridges, canals and roads. For example, The Atlas Portland Cement Company in Hannibal, MO produced much of the cement needed for The Panama Canal and the Empire State Building. Cement is also a key ingredient in stucco, grout and mortar. At the turn of the century, some cement companies also attracted a lot of immigrant workers especially from Europe which in some cases produced new towns or added people to existing towns and helped boost the economy. Modern cement companies rely more on machinery and technology than large labor forces. Cement companies also create quarries which can serve as wildlife habitat when the company is finished with the site. Some cement companies also burn hazardous waste for fuel (which is a good thing as it keeps the hazardous waste from being dumped or buried).
We are one of the largest concrete admixture-products manufacture in China. We can produce different kinds of high quality conveyor belt and transmission belt.
