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.

. 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:Can you help me identfity the additive and muliplicative inverse for the following numbers?-10-0.1254/3How do you find the answer?
Additive inverse : what number adds to it to make 0 (i.e multiply it by -1) Multupicative inverse : what number multiplies to it to make 1 (i.e. find the reciprocal
Q:I have heard that they are not and the necessary bacteria is there from the human waste dumped into the tank. There are numerous sites that say additives are necessary and of course those sites recommend you buy it from them. So is there ever a reason to use them and which ones if any are good and which ones are scams?Also I know someone who says they haven‘t had their tank pumped in 10 years and it still works fine, but every septic site says to pump your tank every 1-3 years. Will the bacteria in a well maintained tank naturally destroy the solids making pumping unnecessary?
Solder and close them up AFTER testing the solder! Nothing is going to happen in either event. There is really no need to awaken a sleeping bear in Boston.there may be codes that all you are doing MUST be done by a licensed plumber! You do not want to get into that mess! Goldwing
Q:I really just want to make my motor last longer, and better MPGWill STABIL help me? or waste of money?Ofcourse i will be using them around every 6 months.
Since you ride every day (lucky you) there is no need for Sta-Bil. I use Sta-Bil because I store my motorcycles for upwards of 5 months a year (unlucky me). Instead of Sta-Bil, run some Chevron Techron into the gas once or twice a year. Helps remove deposits in the carburetor or fuel injection system. Good Luck
Q:What roles do food additives play in the colour and flavour of food and in the preservation of some food items?
Additives in food can increase the nutrition value e.g. added fiber, Vitamin C, Vitamin D etc. Obviously additives are used to preserve foods making them last longer and also to change or enhance the color of foods. I've heard that some supermarkets use additives to keep the outside of fresh meat looking red or pink so it looks fresh longer than it should.
Q:I know they have scented additives that make exhaust smell like cherries and fruits but do they have any for coloring?
NO. However, high quality lubricants in engine, trans and dif might help. Good tune up and, if your mechanically inclined, hydrogen injection, will make a difference.
Q:ok im doing a report on food additives and was wondering if you knew some names or good website for this. i mean additives like KFC inject into their chicks to make them bigger. or Monsanto (think that was it) inject into their cows to make them produce more milk. anything to do with animals thanks
Some used to use diethylstilbestrol (DES), but they stopped that around 1960 because it caused cancer in women. Since then it has been illegal to use hormones or steroids in chicken at all. They might be using other kinds of additives now, but none that I know of, sorry. However, one thing to look out for lately has been genetic modification to chickens to make them grow larger and quicker.
Q:I usually stock up with chobani. I figure it is still having some sugar which is not good. Any healthier options please?
Q:I think it might be postive 2 over a But then again, I‘ve been wrong before.
my 9yo QH gets MSM (she has loud joints and I just started working her a lot, so I want her joints to stay healthy!) and Stress-dex electrolytes (she's not a big water drinker) also garlic for flys. I try to keep her as natural as possible, so not too many supplements.
Q:Besides compost, what are some good garden soil additives and where can I get them?
Depending on your soil, most additives are available at a local garden center. You first need to decide what your soil needs. Take a good sized sample with your and the garden center might be able to help you. Don't go to Lowe's or Home Depot; they don't know jack about conditioning soil. Go to a locally owned and operated real garden center. Most often, dehydrated cow manure is a good one. Once again, the stuff the big box stores sell is worthless, it's already got all the good out of it. Leaf compost will help loosen the soil but if you use leaves, you will need to use some lime. If you can get it, mushroom house soil is wonderful stuff. It's sterilized chicken manure, shredded corn cobs and peat moss. But that's not available in all areas of the country. Rabbit manure is great! It won't burn your plants and doesn't stink to high heavens. If you know someone who has pet bunnies, get them to start saving their stuff in clean cat litter buckets so you can dump it on the garden and then till it in next spring. A little straw or wood shavings won't hurt a thing either.
Q:Can someone please explain to me in layman‘s terms the difference between additive and subtractive colors? I have looked for this on the web but it is all to confusing.
Subtractive colors the colros are generated from the light source in the area. like the sun, a flash, lamps etc. When you print you are using subtractive colors. CMYK Cyan Magenta Yellow and Black. printed materials will be printed in using these colors. Light will hit the ink and it subtracts everthing except that color. so when you look at a cyan (light blue) color on an ad in a magazine the light is hitting the paper and all the other colors in the sepctrum are being removed thus allowing you to see just the cyan. and if I want purple I need to subract the with cyan and magenta inks Additive colors are Red Green and Blue. These are used on things like computer screens and TV's. The main source of the color is the electronics it's self. since it is generating the colors nothing gets subtracted only added. thus they are additive colors. so to make purple I need to add blue and red.
