In addition, the volume of the steel bar corrosion product is about 2.5-7 times of the original volume, the generated expansion pressure can cause cracking and peeling of concrete, and the cracking can cause more corrosive media to enter, so that more serious corrosion is caused. Therefore, most of the early hydraulic engineering is exposed in the nature for a long time, and is degraded to different degrees under the influence of water soaking or natural environment, and in order to guarantee the service life of concrete, the concrete is generally required to be repaired and protected to meet the use requirement.
At present, the domestic hydraulic engineering restoration technology uses an organic polymer material mixture to protect concrete, the organic polymer material has excellent weather resistance and water resistance, and is easy for field construction and curing forming, and the bonding effect formed between the organic polymer material and the concrete is the key for realizing long-term effective surface protection, but many materials can still be peeled off or easily washed out even reaching more than 3MPa when the materials are tested to be pulled, so how to improve the positive tensile strength and the anti-abrasion performance of the restoration material is an effective means for improving the concrete protection.
