The seam an agent - polymer mortar and interface Concrete surface mending ideal material

Concrete surface mending material 1. Concrete repairing material can use the processing interface seam an agent and polymer repair mortar ( Polymer mortar) , polymer mortar compressive strength, tensile strength, bending strength should not be lower than the base concrete. 2. Concrete surface protection material should be based on the actual engineering need to choose, can use inorganic materials, organic polymer materials and composite materials. And comply with the following provisions: 1 protective material should meet the requirements of structure durability protection, according to the different environmental conditions and durability damage types should be respectively has the carbonation resistance, permeability resistance, resistance to chlorine ion and sulfate erosion, protecting steel performance. 2 under the environment by erosion, the protective material shall not occur ballooning, dissolved, embrittlement and cracking phenomenon. 3 for protective layer of the role of anti-wear, should be within its service life is not the wear and threshing structure surface. 4 strong protective layer and the concrete surface binding, within its service life, should not appear crack, empty drum, flaking off.
