Product Description

Parameters

1. Product introduction

1. Specifications: 250kg/barrel, 1 ton/barrel, and bulk.

2. Density (20℃) 1.01±0.03g/cm3)

3. PH value (20℃): 9.0±1.0

4. Chloride ion content: ≤0.1%

5. Alkali content: ≤1.0%

6. Appropriate dosage: 0.5-0.6% of the total mass of the cementitious material, the optimum dosage is determined by the trial compounding results.

2. Scope and performance:

1. Scope of application: It is mainly suitable for concrete batching plants, pipe pile enterprises, component enterprises, railway and water conservancy projects, etc.

2. Use effect:

(1) In the case of keeping the concrete mix ratio unchanged, the synergist can be added according to 0.5-0.6% of the total mass of the cementitious material. The 7-day compressive strength of concrete was increased by 3-5MPa and the 28-day compressive strength was 3-8MPa, and the working performance of concrete was significantly improved;

(2) Can reduce the amount of cement by 10-20% under the condition that the concrete strength remains unchanged, the working performance is the same, and the water-binder ratio is the same. At the same time, the amount of slurry can be significantly increased, and the rheological properties of concrete can be improved.

3. How to use

1. Dosage: 0.5-0.6% of the total mass of the cementitious material, the optimum dosage is determined by the trial mix results;

2. Specific method: when it is not necessary to raise the adding height, you can directly use the metering pump to meter it;

When it is necessary to increase the feeding height of the synergist, it is generally added by the method of secondary pumping. The schematic diagram is as follows:

JT-ZX Series Concrete Glue Reducer

For companies that use our glue reducer, we provide customers with storage tanks and related metering devices and methods of testing and controlling the amount of feeding.

4. Use examples

1. The trial results of the S batching plant in Nanning, Guangxi

Test number	Concrete design label	Cement kg/m³	Mineral powder kg/ m³	Fly ash kg/ m³	River sand kg/ m³	Stone kg/m m³	Water kg/m³	Admixture kg/ m³	Synergist kg/ m³	Machine slump/mm	Out-of-machine expansion/mm	1 hour slump/mm	1 hour expansion/mm	7-day compressive strength/MPa	28-day compressive strength/MPa
ZS-1	C30	180	80	85	880	1010	162	9.66	0	205	490	190	410	29.0	42.6

Note: All raw materials are provided by this batching plant, the dosage of synergist is 0.6% of the total mass of cementitious materials, and the concrete mix ratio has not been adjusted.

2. Industrial trial test results of X mixing station in Nanning City, Guangxi Province

Test number	Concrete design label	Cement kg/m³	Fly ash kg/ m³	River sand kg/ m³	Machine-made sand kg/ m³	Stone kg /m³	Water kg/m³	Admixture kg/ m³	Synergist kg/ m³	Machine slump/mm	Out-of-machine expansion/mm	1 hour slump/mm	1 hour expansion/mm	7-day compressive strength/MPa	28-day compressive strength/MPa
ZS-1	C30	275	60	450	479	960	158	8.0	0	195	550	195	415	30.4	37.8
ZS-2	C30	250	60	460	489	960	146	8.0	1.86	205	585	195	535	32.4	40.8

Note: All raw materials are provided by this batching plant, the amount of synergist is 0.6% of the total mass of cementitious materials, the amount of cement is reduced by 25kg, and the water-binder ratio remains unchanged.

5. Economic Estimates

The use of this synergist can save 10-20% of the cement consumption under the condition that the working performance and compressive strength of the concrete remain unchanged, and the same amount of machine-made sand, river sand, pulverized coal, etc. can be used to supplement.

Direct economic benefit = cement price & times; cement saving amount - synergist price & times; use amount of synergist - machine-made sand price & times; machine-made sand increase + admixture price & times; admixture saving amount

6. Features of use:

1. It can improve the working performance of fresh concrete, improve workability and reduce bleeding;

2. It can increase concrete compactness, improve impermeability and reduce concrete cracks;

3. It can improve the freeze-thaw resistance and carbonization resistance of concrete;

4. This product is non-toxic and harmless, has zero emission in production, and is a green and environmentally friendly building material.

7. Precautions

1. Before use, first check the company's logo according to the factory inspection report and label, and confirm that the product and model are correct before putting it into use;

2. When further verifying product performance, the following methods can be used:

3. Consistency acceptance, under the same temperature conditions, the density, pH and solid content of the newly arrived synergist and the retained sample of the qualified synergist are detected. When the difference in density between the two is ± ;0.6, when the difference of solid content is ±2%, it is qualified;

4. According to the proportion of cement, fly ash and mineral powder in the total amount of cementitious materials in a certain grade of concrete mix, carry out a comparative test of compressive strength of mortar, and add new synergists during the test. Compared with the qualified synergist, when the 7-day compressive strength of the mortar mixed with the two synergists is within the allowable error range of +plusmn; 5%, the new synergist is regarded as qualified.

5. The first method is recommended when the synergist is used continuously, and the second method is used when there is a big difference in the quality of the synergist.

6. The synergist 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;

7. This product is slightly corrosive to the skin. After contact with the skin, it should be washed with water, and it is strictly forbidden to eat;

8. This product can be added with water reducing agent at the same time;

9. The shelf life of this product is: 6 months.
