Product Description
Parameters

1. Product Features

The product is liquid, and it is packaged in tons, 250kg barrels and bulk.

Density: (20℃)1.20-1.25(g/cm3)

PH: (20℃)8.00-9.50

Solid content: 40-55 (%)

Suitable dosage: 0.15-0.2%

2. Scope and performance

Mainly used for the preparation of admixtures for concrete.

When the admixture is prepared by grinding, the activator can increase the hourly output of the mill and improve the particle composition of the admixture when the moisture content of the grinding material is not more than 1.%.

The use of the activator to produce admixtures can accelerate the activity of mineral admixtures and improve the activity of admixtures, thereby reducing the amount of mineral powder, fly ash or cement in concrete and reducing concrete production costs.

4. Features of using this activator

1. The fluidity of the admixture will increase.

2. The delay loss of the fluidity of the admixture slurry is reduced.

3. The water consumption of standard consistency is slightly reduced.

5. How to join when using

It is not necessary to increase the adding height of grinding aid, and it can be directly added by metering pump.

When the feeding height needs to be raised, it is generally added by the method of secondary pumping. The schematic diagram is as follows:

JT-H系列掺合料活化剂

For companies that use our grinding aids, we provide customers with storage tanks and related metering devices and methods of testing and controlling the amount of feed.

6. Precautions

1. This activator should be used after passing the inspection. Acceptance inspection methods are:

1) A relatively simple method is to detect the density, pH value and color, or solid content of the newly arrived activator and the activator that has been proved qualified under the same temperature conditions, when the two are within the error range. It can be considered qualified and put into use;

2) Use an additive-free admixture with the same composition as the production admixture, and at the same time in the same laboratory, use the retained sample of the activator that has been certified as qualified and the newly arrived activator sample, according to the admixture. Carry out the mortar strength blending test in the concrete with the cement dosage ratio (for example, in C30 concrete, the cement dosage is 450kg/square and the admixture dosage is 90kg/square, then the ratio of admixture to cement is 1:5, and the mortar strength is When molding, the admixture is matched with cement according to 1:5), when the three-day strength of the two is within the error range, it is qualified; when the activator is used continuously, the first method is generally used, which has a significant impact on the quality of the activator. The second method is only used when there is a big difference.

2. The activator should be prevented from being dropped, smashed, squeezed by external force and approaching high temperature during handling and storage, and the stacking height should not exceed two barrels;

3. Check the company's logo before opening the cover to confirm that the product and model are correct before putting it into use;

4. This product is slightly corrosive to the skin. After contact with the skin, it should be washed with water, and it should not be eaten by mouth;

5. When using this product, when the ambient temperature is lower than -5℃ for 5 consecutive days, insulation measures should be taken to prevent the product from crystallizing and affecting normal use.

6. The shelf life of this product is 12 months.
