How to solve the problem of wall sanding due to unqualified rebound strength of concrete

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

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:

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 once the strength is increased, it can maintain long-term stability;

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

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

5. Green and environmental protection: free of heavy metals, harmless, incombustible, nonvolatile, formaldehyde and VOC content is far below the industry standards, 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:

usage method:

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. Long wool is recommended for construction roller Roll coating: Z2-T is repeatedly applied for the first time 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 coating shall be carried out in the same way as the first coating, and the continuous coating shall be carried out until there is no 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 completion of the next painting, and the effect is basically achieved in about five days. During this period, do not water or rain;

5. The construction environment temperature is between 0-40 ℃, and the common temperature is between 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:

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.
