Some Treatment Methods for the Poor Strength of Concrete Columns in Hejian City

Hejian concrete column Some treatment methods for poor strength

Xianghuan concrete Z2 concrete hardening agent (strengthening agent) (strengthening type, special use for improving rebound strength) is a high-tech product developed by our company. On the basis of Z2 universal type, penetration enhancer and multiple effective ingredients are added, which has stronger penetration ability and can penetrate deeper base course, with better effect and more remarkable results. expert door It is used to solve the problems of low surface strength and insufficient rebound strength of poured concrete. The rebound value of treated base course can generally be increased by 5% - 30% (about 2-10 rebound values), and has a certain reduction effect on the degree of high carbonization.

Scope of application of Xianghuan concrete Z2 concrete hardening agent (reinforcing agent):

The strength of poured concrete is low due to curing, mix ratio, use of additives, freezing and other reasons; The rebound strength caused by concrete surface carbonization is low. Including: ground, wall, column, bridge, tunnel, etc.

Use method of Xianghuan concrete Z2 concrete hardening agent (reinforcing agent):

1. Stir the product before use;

2. The concrete surface shall be kept dry. If the concrete surface density is high, it shall be polished;

3. Long wool is recommended for construction roller Roll coating: firstly, continuously and repeatedly brush until the base course is no longer permeable and the surface is completely wet;

After 5-6 hours of storage, after the materials are basically dry and absorbed, the second coat shall be applied with the same method as above, and the continuous coating shall be applied until no further penetration; After another 5-6 hours, the next time, and so on. It is recommended to paint six times, with an interval of 5-6 hours, and each time should be fully painted until it is impermeable.

4. The rebound test can be carried out two days after the sixth painting, and the effect is basically achieved in about five days. During this period, do not water or rain.

It should be emphasized that: The strength and hardness of concrete are related to the number of times of material immersion (unit dosage) and the time of material contact reaction. The construction methods for different concrete buildings and different grades of concrete are almost the same, but they are adjusted according to different base conditions, which determine the absorption (unit dosage).

If you still have some questions about our products, it doesn't matter. We can provide you with samples below the cost price. You can do experiments first, and then purchase in batches if you are satisfied with the results. You can consult technical personnel for material selection and scheme

Xianghuan concrete Z2-T concrete reinforcing agent is environmentally friendly, harmless, safe and easy to use. It can quickly penetrate into the concrete, and can be compared with the unhydrated cement And cement hydration by-products, such as calcium hydroxide, react to generate a large number of vine like calcium carbide crystals, block the pores and form a three-dimensional network structure, increase the compactness of concrete, greatly improve the strength and hardness of concrete surface, and form a long-term closed, rock hard, steel hard surface. In addition, it also has the function of reducing carbonization high-rise and improving durability.

Xianghuan concrete Z2-T concrete reinforcing agent apply Range:

The surface strength of poured concrete is low due to curing, mix proportion, use of additives, freezing and other reasons; The rebound strength caused by concrete surface carbonization is low. Including: ground, wall, beam column, bridge, wharf, tunnel, etc.

Performance characteristics of Xianghuan concrete Z2-T concrete reinforcing agent:

1. Rapid penetration: generally, it can penetrate to 2mm-2cm below the concrete surface after three days;

2. Durability enhancement: using this product alone can improve the concrete strength by 20-40%, and up to 45%. And once the strength is increased, it can maintain long-term stability;

3. Rapid onset: generally, the effect is obvious after 3 days, and stable after one week;

4. Keep the appearance: the appearance of the painted concrete and the original base course have no obvious change;

five Green and environmental protection: free of heavy metals, harmless, nonflammable, nonvolatile, formaldehyde and VOC content is far lower than the industry standard, meeting the requirements of indoor environmental protection;

6. Easy to use: direct spraying and roller coating. Time and labor saving;

7. Reducing carbonation: this product can slow down and reduce the carbonation value of concrete to a certain extent.

8. Parameters:

Application method of Xianghuan concrete Z2-T concrete reinforcing agent:

1. Stir the Z2-T well before use;

2. The concrete surface shall be kept clean and dry. If the concrete surface has high density or oil stain, it shall be polished;

3. For construction, it is recommended to use long hair roller roller coating, and brush Z2-T continuously and repeatedly until the base course is no longer permeable and the surface is completely wet; After 5-6 hours of storage, after the materials are basically dry and absorbed, the second coat shall be applied with the same method as above, and the continuous coating shall be applied until no further penetration; After another 5-6 hours, the next time, and so on. It is recommended to paint six times, with an interval of 5-6 hours, and each time should be fully painted until it is impermeable;

four sixth The rebound test can be carried out two days after the coating is completed, and the effect is basically achieved in about five days. During this period, do not water or rain;

5. The construction environment temperature should be between 0-40 ℃ and 10-30 ℃;

6. The tools after construction shall be cleaned with clean water as soon as possible.

Tip: If used excessively, a small amount of white powder may precipitate after drying. To avoid affecting the appearance, wipe it off with a clean rag.

Storage, packaging and precautions of Xianghuan concrete Z2-T concrete reinforcing agent:

Storage: This product should be stored in a ventilated and cool place, sealed storage.

Package: 50kg/barrel.

Precautions: This product is harmless and incombustible. Contact glaze or Glass The surface shall be cleaned with water immediately after finishing so as not to affect the appearance.

**The product description of Xianghuan concrete Z2-T concrete reinforcing agent is based on our test results and years of on-site practical experience. In view of the complexity of the concrete itself, our use suggestions cannot cover all possible situations. When using it in a large area, we recommend that you first test in a small area or communicate with our technical department to ensure the use effect of the product.
