JT-H series admixture activator

Primarily suitable for the preparation of concrete admixtures. When used in the preparation of admixtures via grinding, and when the moisture content of the raw materials is no more than 1%, this activator can increase the mill output and improve the particle size distribution of the admixture. Using this activator in the production of admixtures can accelerate the development of mineral admixture activity, improve admixture activity, and thus reduce the amount of mineral powder, fly ash, or cement in concrete, reducing the cost of concrete production.

Details

I. Product Characteristics

The product is a liquid, available in three packaging options: one-ton packages, 250kg drums, and bulk packaging.

Density: (20℃) 1.20-1.25 (g/cm3)

PH: (20℃) 8.00-9.50

Solid Content: 40-55 (%)

Suitable Dosage: 0.15-0.2%

II. Application Scope and Effects

Mainly suitable for the preparation of concrete admixtures.

When used in the preparation of admixtures by grinding, this activator can increase mill output and improve the particle size distribution of the admixture when the moisture content of the materials entering the mill is no more than 1%.

Using this activator in admixture production can accelerate the activation of mineral admixtures, improve admixture activity, and thus reduce the amount of mineral powder, fly ash, or cement in concrete, reducing concrete production costs.

IV. Characteristics of Using This Activator

1. The fluidity of the admixture will increase.

2. The time-dependent loss of neat cement paste fluidity is reduced.

3. The water requirement for standard consistency is slightly reduced.

V. Adding Method During Use

If no height adjustment is needed for the grinding aid, it can be added directly using a metering pump.

If height adjustment is required for feeding, it is generally added using a two-stage pump method. The schematic diagram is as follows:

For companies using our grinding aid, we provide customers with storage tanks, related metering devices, and methods for testing and controlling the feeding amount.

VI. Precautions

1. This activator should be used after passing inspection. Inspection methods include:

1) A simple method is to test the density, PH value, and color, or solid content of the newly arrived activator and the sample of the activator that has been proven qualified after use under the same temperature conditions. When the two are within the error range, it can be considered qualified for use;

2) Using an additive-free admixture with the same composition as the produced admixture, a mortar strength test is conducted in the same laboratory using both the sample of the activator that has been confirmed as qualified after use and a sample of the newly arrived activator, according to the ratio of the admixture to cement in the concrete (e.g., if the cement usage in C30 concrete is 450kg/m³, and the admixture usage is 90kg/m³, then the ratio of admixture to cement is 1:5, and the mortar strength is mixed at a ratio of 1:5 during molding). When the three-day strength of the two is within the error range, it is considered qualified; the first method is generally used when using the activator continuously, and the second method is only used when there is a significant discrepancy in the quality of the activator.

2. During transportation and storage, prevent dropping, striking, external force compression, and proximity to high temperatures. The stacking height should not exceed two drums;

3. Check the company's label before opening the seal to ensure that the product and model are correct before use;

4. This product has a slight corrosive effect on the skin. Wash with water after skin contact, and it must not be ingested;

5. When using this product, if the ambient temperature is continuously below -5℃ for five consecutive days, insulation measures should be taken to prevent product crystallization from affecting normal use.

6. Shelf life: 12 months.
