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:Is cement cheaper than wood?
Cement no, But cement block is cheaper but it ugly.
Q:What can be done with cement from a building that has been burnt?
Concrete from demolished buildings can be used for erosion control provided it is not contaminated with toxic or other environmentally negative materials. It can also be used as faux stone if broken into pieces of the correct size and stained to look like stone. One of our neighbors has a large retaining wall made from this type of reclaimed concrete.
Q:how much gravel and sand could be mixed for 1 bag of cement?
a bag of cement contains one cubic foot of will need 3 cu. ft. of gravel and 2 cu. ft. of sand per batch...
Q:How Can I Take Off Cement From A Cat?
you should def. consider a vet visit. sometimes you can even find a vet that will do a free 1st examination and then find out how much it will cost you for them to get this cement off. but you should def. go soon before the cats skin is damaged even more.
Q:Can I use cement board under my toilet?
Yes cement board is the only thing i would be using in a wet area such as toilet, laundry or bathroom as if there are any leaks or overflows the floor will not rot. Not to sure about using carpet in toilet i would probably suggest vinyl or tiles.
Q:who invented cement first?
Romans but it's not the cement that we know now. The main component was volcanic ash. If you're referring to the modern day cement, it's Louis Vicat and Joseph Asdin for ordinary portland cement.
Q:which does not form a part of reinforced cement concrete?
Lime and silica make about 85% of the mass of cement. However, lime by itself is not used in the production of Portland cement concrete mixtures. Hydrated lime is usually used in the production of asphaltic concrete mixtures. See the links below for more information.
Q:cement flammability?
You have to have a combustable material in a finely ground form to produce an explosion. Cement dust is inorganic, and non-combustable therefore you are not at risk of the silo exploding unless you fill it with raw gas from the cutting rigs before they try to cut it.
Q:Can you lay cement board in order to put vinyl flooring?
I would not put down cement board. If you want a smooth surface to lay the vinyl over (any lump, bump or irregularity will show through vinyl) use plywood.
Q:Is Cement Terrazzo an antistatic floor?
You don't buy it, someone has to be hired to custom make it on site. If you re=ask the question under do-it-yourself category, that you would get way more answers. Good Luck
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.
