1.With high water-reducing ratio 2.With good strength-increasing effect 3.The cement consumption can be save above 20%

TJ-9 Polycarboxylic Acid High-performance Water-reducing Admixture

This product complies with China national standard of concrete admixture (GB8076-2008).

This product, which is the high-performance water-reducing admixture after the ordinary water-reducing admixture represented by calcium lignosulfonate and the high-efficiency water-reducing admixture represented by naphthalene series of products have developed, is also a wholly new kind of high-performance water-reducing admixture of water-reducing mechanism and molecular structure. Compared with the naphthalene series of products, it has a series of advantages of low adding amount, high water-reducing rate, good maintaining performance of concrete mixture slump, significant strength-increasing effect, low shrinkage, low alkali content, moderate air-entrainment and good environmental performance, and it has a qualitative improvement to the comprehensive performance of concrete.

I. Purpose of Product

This product has the advantages of high water-reducing ratio, good anti-slump property and good durability. It is especially suitable for preparing high-strength and high-performance concrete, such as cast-in-situ concrete, pre-stressed reinforced concrete, pumped concrete, self-leveling & self-compacting concrete, grouting pile concrete, etc. in the works like railway, bridge, water conservancy, port and municipal project.

II. Main Performances of Product

1. This product is colorless or yellowish water solution. It has no toxicity, inflammable and pollution.

2. With high water-reducing ratio, adding 0.8~1.2% of this product into concrete and can reduce 28~36% water consumption under the situation of maintaining the same slump.

3. With good strength-increasing effect, the strength of concrete can be improved 60~80% in 3 days and improved about 30% in 28 days after this product is applied.

4. Under the situation of maintaining the same mixing proportion and strength, the cement consumption can be saved above 20%.

5. With good workability and fluidity, this product can greatly improve the pumpability and reduce the labor intensity of construction.

6. With small shrinkage and good durability, this product is suitable for the application of high-strength and high-performance concrete, such as high-performance concrete in special railway line, magnetic suspension, expressway, overhead road, etc.

III. Usage

1. Its dosage is 0.8~1.2% of total cementing material and the best one should be subject to relevant experiment.

2. When this product is applied, the mixing time should be appropriately extended in order to mix fully and evenly

3. Under the situation of meeting the concrete slump, the water should be reduced as much as possible to avoid giving rise to the segregation.

IV. Packing

This product is packed by two kinds of plastic barrels. One loads 200 kilos, its diameter is 58cm and its height is 89cm. The other loads 1000 kilos and its measurement is 1.2m*1.2m*1m. Meanwhile, it can be packed by felxitank.
