Abstract: The paper overviews the trajectory of additives and defoamers in traditional concrete, with the stress on the classification and defoaming mechanism of defoamers in concrete, including common surface-active effects and long-chain lubrication. It also briefly summarizes existing researches on various types of defoamers in concrete. It focuses on the domestic and international researches on the modification of new defoamers in concrete and their application, and suggests that new types of environmental-friendly and multifunctional defoamers will be the most suitable additives for concrete in the future.
Keywords: concrete; defoamer; defoaming mechanism; modification application
