Do you know what epoxy grouting glue is? It is a resin glue specially designed for repairing concrete cracks. Epoxy resin grouting glue can easily solve the fine cracks in concrete, whether it is walls, floors, floors, or columns, it can be repaired. It also has the advantages of low viscosity, low tension, and strong penetration, and can achieve traceless surface repair.
Everyone knows that in the modern construction industry, concrete, as a major building material, is widely used in various projects. However, due to various factors such as construction, environment, and materials, concrete cracks occur from time to time, seriously affecting the integrity and safety of the structure.
To solve this problem, professional epoxy resin grouting glue emerged at the historic moment and became the first-choice material for concrete crack repair. This article will introduce in detail the characteristics of epoxy resin grouting glue, crack repair principles, and crack treatment processes.
Crack repair principle of epoxy resin grouting glue
When cracks appear in concrete, traditional repair methods often simply treat the surface and ignore the problems deep within the cracks. Epoxy resin grouting glue adopts a more thorough repair strategy.
The crack repair principle of epoxy resin grouting glue is mainly based on its high permeability and self-filling ability. The following is the detailed repair principle:
High permeability: Epoxy resin grouting glue has excellent high permeability. When colloid is injected into a crack, it will quickly penetrate the bottom of the crack and into the tiny gaps, ensuring that every inch of the crack is nourished by the colloid.
Self-filling ability: Due to the low viscosity and high fluidity of epoxy resin grouting glue, it will automatically fill every corner of the crack, no matter how subtle or complex the crack is.
Repair and reinforcement: When the epoxy resin grouting glue penetrates and fills the bottom of the crack, it will start the curing process. The cured epoxy resin has extremely high strength and adhesiveness, and can effectively bond the concrete on both sides of the crack firmly together to form a whole. This kind of repair method not only treats the surface, but also strengthens the entire matrix, thereby restoring and enhancing the overall strength and stability of the concrete structure.
The crack repair principle of epoxy resin grouting glue is to use its high permeability and automatic filling ability to penetrate deep into the bottom of the crack to perform all-round repair and reinforcement. This method of repair ensures the integrity and safety of the concrete structure, providing a long-lasting, effective solution.
Six major characteristics of epoxy resin grouting glue
1. Low viscosity:
Epoxy grouting glue has a lower viscosity, which allows it to be injected into the crack more smoothly during the construction process, ensuring that every part of the crack can be fully filled. Low viscosity also helps improve application efficiency and reduce application time.
2. High intensity:
Once cured, epoxy grouts provide extremely strong bonds. It can firmly bond both sides of concrete cracks, ensuring that the repaired structure can withstand larger loads and restore its original strength.
3. High fluidity:
The high flowability of epoxy grout means it can flow freely in cracks and penetrate every corner, ensuring complete filling without bubbles or hollows. This feature ensures complete repair of cracks, reducing the likelihood of recurrence.
4. No shrinkage when cured:
Unlike other repair materials, epoxy grout virtually does not shrink during the curing process. This feature ensures that the repaired surface remains flat and does not cause new cracks or deformation due to shrinkage.
5. Widely used:
Epoxy resin grouting adhesive has a wide range of applicability and can be used to repair concrete cracks of various types and sizes. Whether it is a bridge, road, building or other concrete structure, it can be repaired using this glue.
6. Simple construction:
The construction of epoxy resin grouting glue is relatively simple. You only need to mix components A and B according to the proportion, and then use a special tool to inject into the crack. Its simple construction process allows even non-professionals to carry out restoration work.
In summary, these six characteristics of epoxy resin grouting glue make it the first choice material for concrete crack repair. Whether it is a civil building or a large infrastructure, it can provide excellent performance and ensure structural integrity and safety.
How to use epoxy resin grouting glue
Step 1: Clean the cracks
First, use a brush to clean the crack and the debris around it to ensure that the inside of the crack is dry and free of impurities.
Step 2: Simple glue adjustment
Mix according to the proportion requirements and use after stirring evenly. It is recommended to deploy according to actual needs to avoid material waste.
Step 3: Colloidal injection
Inject the mixed colloid into the cracks of the concrete in batches until the cracks are filled.
Step 4: Wait for curing
After the injection is completed, sprinkle quartz sand and other materials on the surface of the colloid and wait for the colloid to completely solidify. Once cured, sanding can be easily carried out.
