Polycarboxylic Acid Water Reducing Agent

Short Description:

This product is a powder polycarboxylic acid water reducer with high water reduction and high collapse type.In addition to the characteristics of the inherent powder water reducer, its biggest advantage is that it has a very excellent collapse preservation.It can prepare a liquid water absorber directly dissolved with water, and each performance index can achieve the performance of the liquid polycarboxylic acid pump agent, which makes it greatly convenient in the application process.The product is configured into liquid and is suitable for the scope of liquid polycarboxylic acid water reducer, widely used for the concrete construction of railway, highway, water conservancy and hydropower, industrial and civil construction projects.

Performance Index

1. This product has a good water reduction rate, has a good water reduction performance under the low mixing amount, especially in the high grade concrete (above C50) effect, its water reduction rate can reach 38%.
2. This product has good early strength and enhancement effect, and the early strength and enhancement effect of concrete mixed into this product is higher than other types of water reducer.
3. The product has the appropriate gas content, and can be adjusted according to the actual needs of the project.
4. This product does not contain chloride ion, sodium sulfate, with low alkali content, no corrosion to steel bars, so it can greatly improve the concrete durability.
5. This product has size stability, the concrete mixed into the product can effectively improve its shrinkage and distortion performance, and reduce the crack risk.
6. This product has excellent water protection performance, no water extraction, no separation analysis, easier to achieve construction operation.
7. This product does not contain formaldehyde, no ammonia release amount, is an environmentally friendly water reducer

Methods And Precautions

1. Recommended mixing amount: 0.6~2.5% (calculated from the gel material, this mixing amount is the recommended mixing amount, and the precise proportion should be finally determined after the coordination ratio test according to the actual situation).
2. This product can be added to the mixer simultaneously with the mixing water to control the measurement error inWithin 1% and extended mixing time for 30s, water in solution should be deducted from the mixing water.
3. This product shall not be reused with the naphthalene water reducer, and attention should be paid to washing out the storage tank when replacing the admixture.
4. This product is bottled and should be stored in a cool and dry environment of 0-40℃, pay attention to waterproof, damage and shelf life of one year.
