Ⅲ. 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.

- Q: the famous Bird Girl statue has an additive or subtractive techique?
- Subtractive sculpture involves cutting away hard materials to make an image. This was not the case for the Bird Girl sculpture. It was originally a plaster cast, meaning that it accords to the concept of an additive technique as one were soft materials are used (wax, plaster, plasticine) and details can be easily added or changed. So, although four bronze statues were produced from the plaster original, I would still say that the work was produced by means of an additive technique. Check out the defintions at these sites: . .
- Q: 1. The additive inverse of a complex number z is a complex number a such that z + a = 0. What is the additive inverse of the complex number -2+4i ?2. The multiplicative inverse of a complex number z is a complex number m such that z ? m = 1. What is the multiplicative inverse of the complex number 1 - i ?I'm confused on how to do this and it would help if anybody could explain because i have a final over this tomorrow. THANKS
- 1. Additive inverse: To find the additive inverse find what the number added to will equal zero. So basically, set up an equation to finda." z+a=0 -2+4i+a=0 a=2-4i And so the additive inverse of -2+4i is 2-4i. (notice that it was simply the originally number multiplied by -1). 2. Multiplicative inverse: Basically the same thing only the two numbers are multiplied. z*m=1 (1-i)*m=1 m=1/(1-i) So that's the answer. I suppose you should probably simplify it though. 1/(1-i) * (1+i)/(1+i) [multiply by the conjugate of the denominator to get the complex number out of the denominator). (1+i)/(1-i?) (1+i)/(1--1) (1+i)/2 So that's you're answer.
- Q: Nanning where to sell food additives
- Generally in the vicinity of the train station or bus station, the door is ** ** chemical, ** food. Know ** food ingredients
- Q: Want to ask the new car in the run-in time when the need to add additives? My car is Lion 2.5I, the oil is already plus 97, but also need to add additives? Do you need to add your refueling? Also ask, will the additive increase fuel consumption? Thank you for your guidance. Please thank you all
- Fuel additives are usually when the tank fuel is running out or when there is little time (the tank can not leave too much oil), before adding the additive to the tank before adding fuel, and then refuel the fuel to the additive red evenly, must be added before adding Fuel additives, because if added to add oil and then add additives and fuel mixture of uneven, may lead to the effect of additives should not have.
- Q: i is imaginary variable, so in most cases it will equal -1
- Distinguish the multiplicative inverse for which the identity is 1 from the additive inverse for which the identity is 0. So, the additive inverse of - 6 + 2i is + 6 - 2i. To ensure that [number] + [additive inverse] 0.
- Q: What would the additive and multiplicative inverse of 2 be and how do you solve this?
- To find an inverse of a number, you first need to decide what the identity is, for that operation. Considering addition, what number x satisfies the following: a + x a. Clearly its 0, so the identity is 0. Considering multiplication, what number x satisfies the following: ax a The answer is 1, so the identity is 1. Now, the inverse x of a number a is s.t a * x e, . . where * is the operation (addition, multiplication.) and e is the identity. So, for addition, a + x 0 The inverse x will be -a. For multiplication, ax 1 The inverse x will be 1/a. Since in your question a 2, the additive inverse is -2 and the multiplicative inverse is 1/2.
- Q: Such as the first security 3000, then add a bottle of additives after the first Paul how much ah?
- During the running of the new car, the additive should not be added. The number of miles that affect the running is not to be maintained, but no additives are added to the new car.
- Q: Differences between extreme pressure additives and lubricating additives
- Additives are mainly antioxidant antiseptic, antiwear agent, friction improving agent (also known as oily agent), extreme pressure additives, detergents, dispersants, anti-foam agent, anti-emulsifier, rust inhibitor Coagulants, viscosity index improvers and other types. The additives sold in the market are generally more than one of the single additive compound, the difference is that the composition of a single additive and composite additives within the proportion of several single additives only.
- Q: Prove the lemma about existence of additive inverses in Zn. (lemma- theres a (-x) in Zn such that x+(-x)[0]n(-x)+x.)?
- In Zn (-x) is also known as n-x for x positive. In Zn, 0+0 0 and 0 is the additive inverse of 0, 1 +(n-1) 0 in Zn and n-1 is the additive inverse of 1, 2 +(n-2) 0, etc.: k+(n-k) 0
- Q: There‘s like what, 600 different chemicals in a cigarette?Where do tobacco companies buy all of these chemicals they put in their tobacco? Wouldn‘t they need tons of it for how many cigarettes are pumped out a day?
- waste of money on that sewer pipe junk/lotta stories of people picking up water and crunching engines/(water does not compress)
