Experimental Study on the Concrete Protective Materials on the Outer Surface of the Aqueduct

Aiming at the appearance of defects and diseases such as carbonization, cracks, freeze-thaw erosion, and other defects on the outer surface of the aqueduct after many years of operation, the paper develops a new polymer cement-based protective material through experimental research, verifies the relevant performance of the material by conducting accelerated aging tests under different conditions, and applies the research results to actual projects.
