Product Description:

Description

Air entraining admixture which generates a highly stable air void system to prevent damage from freezing and thawing, severe weathering, or deicer chemicals.Based ob a high-grade saponified formulation,it is chemically similar to vinsolbased products, but with increased purity and supply dependability.

Advantages
1. Increases the bond strength and avoid losing of concrete compressive strength because of entrained air.
2. Preserves internal water and effectively reduces permeability
3. Enhances resistance to surface deterioration caused by de-icing chemicals, sulfate attack and corrosive water.
4. Has more stable performance of anti-freezing/thawing compare with other air entraining products.
5. Requires less mixing water used per cubic meter of concrete, therefore bleeding is reduced.
6. Reduces bleeding and segregation of the concrete.
7. Be compatible with other admixtures.
8. Be non-toxic, non-flammable, and corrosion resistant.
9. Has high bonding strength, easier to be pumped and compacted.

Application
Air is introduced into the concrete by the mechanics of mixing and stabilized into millions of discrete semi-microscopic bubbles by AE. These air bubbles act much like flexible ball bearings increasing the mobility, or plasticity and workability of the concrete. This can permit a reduction in mixing water with no loss of slump. Placeability is improved. Bleeding, plastic shrinkage and segregation are minimized.

Through the purposeful entrainment of air, AE remarkably increases the durability of concrete when exposed to severe freezing and thawing. It has also demonstrated a remarkable ability to resist the action of frost and deicing salts as well as sulfate, sea and alkaline waters.

Addition Rate
Testing or prior experience with the job materials and job equipment is necessary to determine the proper dosage and minimum mixing time. Recommended addition rate: Add 0.005- 0.015% for mortar or concrete.

Package
The product is packed in polywoven bag with plastic liner at 25kg.

Q:Is soy dietary fiber a food additive?
No, soy dietary fiber is a kind of dietary fiber, in the classification, all the dietary fiber belongs to a can not be digested carbohydrates and carbohydrates in the classification of food raw materials, and flour, sugar, etc. belong to a Classification grade, does not belong to food additives.
Q:what kind of additives i can add to my car?
PLEASE do not put your trust in thesemechanic in a can" additives. They are crap. More then anything, they usually do nothing more than mask a problem until its twice as worse. The first suggestion is a tune up for the gas mileage. Without more detail, I can't suggest anything on the freeway pulling problem. It could be anything from an allignment problem to just a bad tire. As for the double fee mechanics, unless you plan on having a man handle these affairs for the rest of your life, its time to take action now. Now I consider myself an honest mechanic (I'm afraid a dying breed), but I understand there are too many crooks and opurtunists out there. However, any women can offset this simply by learning some basic automotive knowledge. Turn the tables on them. NOTHING scares these scam artists more than a women walking in acting like she knows a little about her own car.
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:The animaniacs do a song about food additives. where can i find the lyrics for that song?
No sure what song it is, but its pobably on this site (below)
Q:To do vacuum packaging cooked food need to put those food additives
Improve the senses
Q:What are the types of paint additives?
User's answer more types of additives. Commonly used hardeners, retarders, matting agents and softeners. The additive used to accelerate the hardening and increase the gloss is called the hardener; the slow drying is called the retarder; the matte weaker is called the matting agent; the elasticity for the paint layer is called the softener.
Q:Andy fly fuel additives how? I heard that China is the only high-end additive brand who used?
I recently bought a bottle of this Andy fly from the full effect of gasoline additives and a bottle of sludge remover, used, and feel very good. The oil change oil before the release of the waste oil super black. Feeling good results. You can try, mainly in addition to carbon deposition. Usually Dora high-speed, and then regularly add a pot of detergent engine carbon deposition will be much less, there will not be jitter ah, to speed up the problem is not what ah.
Q:What are the additives in the bottled peanut oil in the supermarket?
Peanut oil light yellow transparent, bright color, smell fragrance, taste delicious, is a relatively easy to digest edible oil. Peanut oil contains more than 80% of unsaturated fatty acids (including oleic acid 41.2%, linoleic acid 37.6%). It also contains 19.9% of saturated fatty acids such as palmitic acid, stearic acid and arachidic acid. Peanut oil fatty acid composition is relatively good, easy to digest and absorb the body.
Q:What is animal feed additives?
Through bio encapsulation,various specific types of minerals,growth promoting substances are given to animals. Normal feed will lack various types of vitamins & minerals,which are then added to an animal's feed for promoting normal health. Blood meal,feather meal,fish meal,fish offal,products from a cannery waste are some other examples.
Q:How to do pesticide residues every day and food additives
In the pesticide residues on the human body to the performance of the three forms of harm, and to introduce acute chronic poisoning and "three" harm. Vegetables from the farmland to the table mainly through two large links and do from the market to the table of this work meaning.
