Application

Applicable to the port, wharf, water conservancy   project,

highway pavement, freeze resistance,

anti-corrosion and seepage control engineerings

require a certain air content of concrete.

This product should be in accordance with the requirements of air content(3~5%), After deploy ,find out the optimum dosage amount of admixture in 0.5~1.5%,water-reducing rate:13~20%.

 

Advantages

1.This product has characteristics of no chlorine, low alkali,delayed coagulation,low slump loss, etc.

2.Right amount added to the product can obviously reduce the concrete surface tension,improve the workability of concrete, reduce bleeding and segregation, improve the impermeability, frost resistance and concrete durability of harmony and so on.

3.This product in concrete can produce small bubbles that is uniform and stable and not easy to damage.

4.After added to this product ,the thermal diffusion, heat transfer coefficient of concrete is reduced. Can improve the volume stability of concrete and various outdoor durability of structure.

5.Can be used for the preparation with requirements of freezing-thawing resistence, test to determine

slump loss before use or Require manufacturers to adjust.

6.Applicable to the preparation of C20-C50 ordinary concrete, Lean concrete, Hydraulic concrete,

Flow of concrete, Commercial concrete, Especially for concrete engineerings with antifreeze and durability requirements.

Q:additive inverse?
The additive inverse is just the same number with the opposite sign. Additive inverse of 6 is -6. Additive inverse of -3 is 3.
Q:Salt, white sugar is not a food additive?
Belong to, not all of the food additives are harmful to the human body. Those countries allow the addition of food modified preservatives can be eaten, no matter what kind of additives, even if it is harmful to the human body as long as the reasonable range is the human body Can only be resolved within the scope of no harm. Moreover, the state is also very important to this piece of food additives, and now there is a pure bio-type food additive polylysine, which is made of lysine polymerization, the main The role of preservative preservation, after eating by the human body is one of the eight essential amino acids, lysine, absolutely non-toxic side effects, you can rest assured that the use of food industry, especially now is the cusp when the anti-corrosion preservative must be careful Consider, must be qualified to the human body harmless additives will have a market, can do more long.
Q:What are the proper subgroups of Q, the additive group of real numbers?
first of all, I assume Q is the rationals, not the reals. (otherwise the rationals are a non-cyclic subgroup). Consider A = {m/n: in lowest terms, there does not exist x such that x^2|n} A is a subgroup of Q. It suffices to show that A is closed under addition. Let m/n, m'/n' be in A. Then there does not exist x such that x^2 | lcm(n,n'). Otherwise X^2 divides n or x^2 divides n'. Consider B = {m/n in lowest terms : 3 does not divide n} also a non-cyclic subgroup. I have no idea how to classify all the subgroups of (Q, +). i think this is a harder problem than you imagined.
Q:The percentage of food additive usage is relative to what
GB2760 which has detailed provisions, such as sorbic acid in the seasoning of the largest increase in the amount of 1g / kg, that other raw materials at least 999g, that is 1000g ingredients inside, sorbic acid dosage can not exceed 1g.
Q:The disadvantages of food additives
Carcinogenic problems. Such as some artificial sweeteners, pigments and other animal experiments confirmed by carcinogenic effects. Such as creamy yellow pigment can induce rat liver cancer, sweetener Ganjing and phenylurea can also cause animal tumors. In recent years also found that the coloring agent sodium nitrite and meat, fish and other foods in the amine react to form a strong carcinogenic nitroso compounds.
Q:Edible oil without any additives can be stored for how long
Seal save for one year is no problem
Q:Baking powder is not a food additive
Is, but in general relatively safe and healthy, for example, we generally use baking soda class, if it is too high uric acid patients also eat more baking soda foods such as soda face
Q:Whether the margarine is a food additive
Definition of International Standards: Margarine is a plastic or liquid emulsified food, mainly water-in-oil (W / O), which is, in principle, processed from edible oils and fats.
Q:Additives for cigarettes
This kind of bio-filter cigarettes, to minimize the harm caused by smoking.
Q:What are the commonly used tire additives?
The thermal oxidation process of organic compounds is a series of free radical chain reactions. Under the action of heat, light or oxygen, the organic molecules first break on the weakest chemical bonds to produce lively free radicals R and hydroperoxides. The hydroperoxide ROOH undergoes a decomposition reaction and also produces a hydrocarbon oxygen radical RO and a hydroxyl radical HO. These free radicals can lead to a series of free radical chain reaction, and finally lead to organic compounds and the nature of the fundamental changes in the structure. The role of antioxidants is to eliminate the free radicals, or to promote the decomposition of hydroperoxide, to prevent the chain reaction. Can eliminate free radical antioxidants are aromatic amines and hindered phenols and other compounds and their derivatives, known as the main antioxidant; can break down the antioxidant antioxidant phosphorus and phosphorus containing organic compounds, known as Auxiliary antioxidant.
