Progress in Study on Protective Polyurea Coatings for Marine Concrete

The influence of aromatic,aliphatic and polyaspartic ester polyurea coatings on anti-frost,anti-permeability of chloride and anti-corrosion property of marine concrete is analyzed,and the research progress of polyurea coating technology in marine concrete is summarized.The present study results show that polyurea coatings could greatly enhance the durability of marine concrete,provide reference for evaluating the protective performance of concretes coatings,and promote the development of protective coating technology for concrete.
