Modified epoxy resin mortar, a high-performance bonding material, has gained widespread application in recent years. This study investigates the mix proportion of modified epoxy resin mortar to provide references for practical applications.

1. Basic Concept of Modified Epoxy Resin Mortar

Modified epoxy resin mortar is a bonding material composed of epoxy resin, curing agents, fillers, pigments, and other components. It exhibits excellent adhesion, compressive strength, and durability, making it suitable for bonding and repairing various architectural structures.

2. Importance of Mix Proportion

The mix proportion is a key factor determining the performance of modified epoxy resin mortar. A rational proportion ensures optimal adhesive strength, compressive strength, and durability, thereby extending the lifespan of buildings. in-depth research on its mix proportion holds significant practical value.

3. Research Methods for Mix Proportion

1. Experimental Design: Before finalizing the proportions, the properties of raw materials (e.g., epoxy resin, curing agents, fillers, pigments) must be thoroughly analyzed, including their physicochemical properties and performance indicators. Experimental conditions, such as temperature, humidity, and mixing speed, should also be strictly controlled.

2. Proportion Calculation: Based on experimental data, mathematical models (e.g., linear regression analysis, multivariate regression analysis, neural networks) are employed to calculate the mix proportions. These models predict the performance metrics of mortar under different proportions, guiding practical applications.

3. Experimental Verification: Performance tests, including adhesion strength, compressive strength, and durability, are conducted on mortar samples with calculated proportions. Experimental results validate the合理性 of the proportion design.

4. Proportion Optimization

During research, optimization methods such as orthogonal experimental design and uniform design are used to screen the optimal proportion scheme from extensive experimental data, enhancing the mortar’s performance.

5. Practical Applications

In practice, the mix proportion should align with specific engineering requirements and environmental conditions. For example:

High-temperature environments: Select heat-resistant epoxy resins.
Wet environments: Use fillers with superior anti-permeability. Additionally, cost-effectiveness and施工 convenience must be considered.
