Air entraining agent is an important material of concrete, the mainly material is triterpenoid saponin, enriching in source and low cost that make sure producing them in large quantity and reducing the cost, it is great ability in market competition.

The mainly function is to improve anti-freeze endure of concrete greatly. In addition, it also can improve construct capability and other complex endure ability of concrete. At present, the main varieties of traditional CS100P/L include rosin soap and pyrolytic polymer of rosin soap, in which exist some defects of poor solubility; poor compound ability with others and heavy lowed ability to concrete strength. CS100P/L of air entraining agent is a high quality air entraining agent with a great applicable promise in domestic concrete project. It owns a lot of superior characteristic, such as to low surface strength of liquor, to produce sealing effect and indie bubble, to produce bubble with a big sparkling amount, small space and long stability, and to improve working function of plastic concrete and endure ability of concrete harden..

Specification
CS100P/L of air entraining agent is natural non-ion surface-active agent, the mainly component is triterpenoid saponin, dissolved water easily, and has strong chemical steadily with acid、alkail and rigidity water. Our company have two kinds of them with powder and liquid. The detail information is described as follows:

Appearance:Brown liquid??? Content for active parts:≥35%??? Surface stress:32.86m.b./m??? Water solubility:Dissolved?
Initial height of bubble:≥180mm???? PH value:5.0-7.0??? Solid content:≥45%?? Proportion:≥18Be

Character
1.?Super quality air bubble
The mixed quantity suggested should be 0.01%-0.06% to the weight of cement, which should be small mixture and low cost. It can cause bubbles in concrete up to 1 billion. The holes diameter varies 0.02mm to 0.2mm, which appears as discontinuous ball with proportional distributing and good stability. When the gas-contain volume is not less than 5%, space modulus L between bubbles will be less than 100μm, while is 6%, L should be about 80μm.
2.?Compound with other additive agent
The water solubility of our product is strong. When it compound with other additive agent, it can adapt to match well and embody mixed domino effect, which is superior to single. It improves some functions in different degree, such as water-diminishing, dispersing, wetting, dissolve-helping, emulsification, adhibit-falling, and so on. It also avoid the phenomena of deposit, color changed, low effect for air entraing. All that can low the cost of compound at least 5%.
3.?Effect to concrete function
The lowing degree to anti-press of concrete are general same with Vinsol Resin, an old brand used in universal, on which this product are superior to other domestic traditional gas-leader remarkably. After mixing with this product, it will be improved of the fluidity and plasticity; while it will be reduced of resinosis and isolation, and anti-folded strength will be improved to 10-20%. The concrete after mixing with this product, it will reduce thermal diffusion and heat exchange modulus while improve its volume stability and endure ability of varied outdoor construction. When used in road construction, it will prolong the usable life for road. If used in pumping concrete, it will improve the fluidity and pumping pressure. The major advantage of this product is to improve anti-icy and anti-salty, and the suitable gas-contain volume should be 3-6% to concrete that require anti-icy. Further more, it also can reduce sinking losses to new-mixed concrete.
Under the same condition, the gas-contain volume is lower than 3%, the anti-press intensity of concrete will not fall but rise a little, while under about 5%, the losing rate of intensity will be no more than 3%. Though CS100P/L will lower the anti-pressed intensity, the gas-contain volume will be less than 5% and anti-folded intensity of concrete will not fall but rise, which is a great advantage to road project.

Except for notable improvement to anti-freeze and salt-frost against of concrete, the test result show that CS100P/L also can improve its endure ability. Small bubbles inducted by gas-leader can be buffer space for volume expand, and it also can lower and stave concrete destroy caused by other physical expand, such as crystalline pressure and salt crystal; as well as caused by chemical expand, such as alkaline bone reaction and sulphate reaction. It show in the test result at the same time that gas-leader can improve anti-osmotic function, for that, gas-leader will be able to improve complex endure ability of concrete.

4.?Application in pumping deliver
In its producing process, if it count with weight of pumping deliver, the quantity added with model CS100P I should be 3-5‰(2% at largest), while added with model CS100L, the quantity should be 6-10‰(4% at largest); if it count with concrete, model CS100P/L I added should be nought point five per ten thousand to nought point eight per ten thousand (three per ten thousand at largest), which will be able to lead to notable effect as follow: (1). To improve water-losing rate. (2). To lower the sinking loss. (3). To reduce resinosis and isolation and with good water-keeping ability (4). With excellent effect for cushion. (5). To reduce frictionalpower and increase fluidity.

5.?Influence to concrete and slurry
Used in concrete and slurry, this product also own lots of functions, such as to induct small bubbles, to reduce water, to improve intensity and plastic, to lower stickiness, to keep water, to reduce deposit, to save concrete, and to prevent penetration, and so on. It's convenient to use for its easy dissolution, not having to heat and needn't add alkali. At the same time, it has a good adaptability to chemical liquor with acid, alkali and salt. Further more, it has no toxicity, no corrosion, no burning. The bubble putamina of concrete and slurry will be thicker after mixed with this product, which will keep better round ball state and the strong sticky ability, as well as easy pumping deliver and easy mashing.

6. Excellent effect of complex application
CS100P/L can improve concrete ability of anti-freeze, endure and tried, and the number of anti-freeze and melt inside the concrete will be up to 200 times, 300 times outside the concrete. At the same time, it could improve easy-mixed ability of concrete, especially used in artificial bone material or natural grit that is a little crude, the effect will be much better. There are many factors that affect gas-leading volume, such as ratio between water and ash, usage amount of concrete, grit ratio, collective material, shocking method, whisking time, sinking degree, and molding temperature, which need to operate strictly according to regulation, or it cannot achieve exact effect. Thus, in order to satisfy gas-containing volume of concrete required by different project, it needs to pass test confirmation in the use process of Model CS100P/L.

Application
1、Used in concrete construction which require endure ability, especially endure ability for anti-freeze, with high demand, such as water work, port work and bridge, and so on.
2.、Used in concrete road and bridge in North.
3、Used in concrete project, which require easy-mixed ability with high demand.
4.、Because it has a strong water solubility and complex ability with other adscititious agent, CS-AE is an important part to make pumping deliver, such as pumping to deliver concrete.
5、Compound with water-minus agent, it can improve easy-mixed ability, reduce resinosis and deposits, as well as to improve endure ability of concrete and anti-erodent ability.
The history for additive agent is no long in China, but it develops quickly, whose super natural surfactant agent answering for environmental demand. With the knowledge that people develop to its function, it will have a great and bright promise.
