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:cement and concrete as composite?
- If your asking if they are composites then yes. Concrete is a composite construction material composed primarily of aggregate, cement, and water. There are many formulations, which provide varied properties. The aggregate is generally a coarse gravel or crushed rocks such as limestone, or granite, along with a fine aggregate such as sand. Portland cement (often referred to as OPC, from Ordinary Portland Cement) is the most common type of cement in general use around the world because it is a basic ingredient of concrete, mortar, stucco and most non-specialty grout. It usually originates from limestone. It is a fine powder produced by grinding Portland cement clinker (more than 90%), a limited amount of calcium sulfate (which controls the set time) and up to 5% minor constituents as allowed by various standards such as the European Standard EN197-1:
- Q:how many bags of portland cement do I need to build a slap of 40m by 30 m by 10cm?
- Contact Portland Cement, their reps will be able do the calculations for you. They will need to know which Portland cement product you are using.
- Q:what dise cemented mean ?
- No,,,, cemented is a natural occurrence where sands and or gravels ly mixed together under ground and slowly become cemented together over a long time period to become a solid mass. What he described above is how to make cement.
- Q:We have an awkward spot in our basement heading down the stairs. We barely have enough spaace to bring bigger items down. We would like to put a 3/4 drywall and glue it to the wall. Is this possible? Can I just use liquid nails?
- Yea you can use liquid nails, but if you ever have to remove it your going to hate it. I'm just wondering though, you stated that you barely have enough space as it is...sooo, don't you think adding 3/4 inch drywall is going to reduce it even more? Why don't you paint it?
- Q:It's already cured for about 36 hours. Is there something i can do? Someone mentioned something about Hydraulic cement. ????????
- There's no such thing as evening out cement once it's cured. It has to be removed and redone. Don't pay the contractor, and have him rip up the whole thing and start from scratch. His mistake... you shouldn't have to pay for it. NOTE: Take digital pictures in case you need to take legal action. A tip: place a newspaper from that day on the ground when taking a picture so that you can prove the date of the pictures.
- Q:Price of laying cement?
- you need to get your local phone book and call all the places in there to find out...
- Q:What is Rietveld method its application in cement industry?Is there any software for calculating clinker phases using this method?
- The Rietveld method uses a powder sample instead of a large single crystal to determine crystal structure by X-Ray Diffraction. This is important in the cement industry because cement is a powder and not crystals of any size. This is useful in determining the quality of the product and adjusting burning conditions in real time. Several different software packages have been developed for this technique.
- Q:just got our driveway done and a boy got a bloody nose and little bit of blood splatters on our new cement, which waslaid 48 hours ago? any help?
- A driveway doesn't have to be perfectly level. If you get a machine sander from a hireall place and powderize the cement in the stained areas to the depth of the stain, you should be able to literally blow it away, then reset new cement in that area if neccessary. Also, you can use cement a bit like the white out paste used in the stationary world, let it set, and you're all good. Which option you take depends on how perfect you want your driveway to look.
- Q:based on the facts that acids and bases can burn skinwhy do you suppose that people that work with BOTH dry and wet cement should be cautios
- The cement is somwhat caustic (not as bad as something like sodium hydroxide, but still able to damage skin on prolonged and/or repeated contact). Both the dry powder and the mixed cement can cause problems: the powder poofs everywhere when empting cement bags and during the initial stages of mixing. It can get inhaled and get on the skin. In both cases, there is moisture present from the body to react and form the semi-caustic mixture. In the case of the already mixed cement, when laying blocks, brick or using a cement pump etc, it is almost impossible to keep from getting splattered with the wet material. Since this type of construction work is often done day after day, a relatively modest amount of skin irritation/damage each day can have cumulative effects and really get to be a problem.
- Q:Hi~My husband is converting our attached garage into a living room. There is a crack down the middle of the cement floor and has caused it to heave a little. There are spots that the floor is uneven. He had planned on making a subfloor above the cement and then laying our new carpet. In the spring there is moisture in there, so now he thinks he needs to rip all the cement and start over. Is that really necessary? Is there some moisture barrier that can be put on the cement? I am not concerned about the uneveness. I think the carpet will hide that. He is a perfectionist and wants everything done right but I don't think its a big deal. Ny concern is the moisture and what to do for that. Thank You
- There is a company called UGL (United Gilsonite Laboratories) that makes paint products specifically for concrete. Many of them are moisture barriers and some are designed for floors. I work in hardware/paint and a lot of my customers go with UGL's products because concrete is what they are designed for. I am sure there are other brands that offer the same qualities, but UGL is the one I am familiar with. Stop in to your local hardware store and someone in the paint department will probably be able to assist you. Hope this helps.
