Brief description of concrete anti-segregation agent

1. Brief description
Concrete anti-segregation agent is a polymer material that is easily soluble in water, and is compounded with high-performance water-absorbing and water-retaining ingredients. It is made of 8 kinds of component materials. It is pure White powder. For concrete or mortar caused by excessive water use, material instability, and over-mixing of admixtures, resulting in concrete bleeding, segregation, and pipe blockage; for unstable concrete raw materials, over-mixing of admixtures, and difficulty in production control, causing serious segregation and pipe blockage, The dead materials on the construction site cannot meet the emergency needs of construction and other situations. It plays the role of adsorbing water, reducing slump, quickly dispersing and evaporating water, and achieves the ideal concrete and mortar state after use.
To achieve the best working performance of concrete, that is, to achieve the best state of workability, fluidity, cohesion, wrapping, homogeneity, and compactness of concrete. No impact on strength or durability.
2. The anti-segregation agent for concrete is not nylon powder. The anti-segregation agent for concrete is white powder, and nylon powder is yellow powder.
3. Compatibility and applicability
                                                                                                                                . The concrete anti-segregation agent has good compatibility and applicability with Nylon series water-reducing agent, aliphatic series water-reducing agent, polycarboxylate water-reducing agent, etc. It can only be used for remedial measures on the construction site or to salvage dead materials. The dosage is very small (30-50 grams/square), which saves trouble, time and effort.
IV. Scope of application
Concrete and mortar:
1. Excessive dosage of admixture leads to concrete segregation.
2. The fine aggregate suddenly becomes coarse and the powder content decreases sharply, resulting in concrete segregation or poor workability.
3. There is no problem with the concrete itself. Just add water and mix at the construction site.
4. The quality of fly ash is too poor, sometimes good or bad, the fineness modulus suddenly becomes smaller or the carbon content suddenly increases.
5. How to use:
Add the concrete anti-segregation agent into the dead material, concrete with poor workability and too large slump, and stir the tanker quickly for 5 minutes, the concrete will return to its normal state. Meet construction requirements.
1. Add about 30-50 grams to 1 square meter of concrete. Depending on the slump of the concrete on site, the amount can be adjusted slightly. If the slump is small, you can add a little less. If the slump is large, you can add a little more.
2. Mix the concrete anti-segregation agent into the concrete and stir the tank truck quickly for 5 minutes, then the concrete will return to its normal state.

6. The use of concrete anti-segregation agents.
Many customers, after receiving the upgraded version of concrete anti-segregation agent, do not know how to use it. Now I will report on the use of concrete anti-segregation agent:
1. Is this concrete anti-segregation agent? Are polycarboxylic acid admixtures and vinyl admixtures common?
Answer: Universal. Except for the aliphatic additives, which are special, the others are universal. The instructions for use only say that it is effective on concrete produced with polycarboxylic acid admixtures, and is also effective on vinyl admixtures.
2. Is the anti-segregation agent component of concrete toxic?
Answer: Non-toxic. Concrete anti-segregation agent is an environmentally friendly and non-toxic polymer material that is easily soluble in water and is compounded with high-performance water-absorbing and water-retaining ingredients.
3. The plasticizer adjusted in the mixing station contributes 3-5 MPa to the strength. The dead material (large water-cement ratio) adjusted at the construction site uses a concrete anti-segregation agent, which does not affect the strength of the concrete.
4. Dosage: 30-50 grams/square, does not affect the quality of concrete (strength and durability). A load of 10-12 square meters of materials only requires one pack per kilogram, which means that spending about 20 yuan on a load of materials can save several thousand yuan. Using concrete anti-segregation agents, one truck of dead material can save thousands of dollars.
5. Some of the concrete in the mixer truck is more serious and some are not too serious. So how to control the degree of separation and mix the anti-segregation agent into the concrete?
                                                                                                                                                                                                                        Adding about 30-50 grams of soil, and finely adjusting the amount according to the slump of the concrete on site, if the slump is small, add a little less, and if the slump is large, add a little more appropriately.
6. It is necessary to turn over the mixer truck and transfer the concrete to the rear of the mixer truck to spread the concrete on the concrete surface to resist segregation.
Remember to sprinkle the anti-segregation agent on the surface of the concrete. If it is sprinkled on the drum of the mixer truck, adhesion will occur. Stir the mixer truck for 5 minutes and then pour it out after mixing evenly. If the concrete in the mixer truck is larger than 15 cubic meters, the concrete anti-segregation agent needs to be added in batches to ensure the effect.
7. Is the strength of concrete adjusted with concrete anti-segregation agent low? It will not be too low and does not affect the strength.
