Abstract With the acceleration of infrastructure construction in China, a large amount of natural sand and gravel aggregates are consumed. At pre-sent, high-quality concrete raw materials are declining. The sign is that the mud content in sand and gravel aggregates is increasing. The mud content in concrete raw materials will affect the dispersion effect of polycarboxylic acid-based water-reducing agents, thereby affecting the performance of concrete. This article reviews the development and application status of many domestic and foreign experts and scholars on the anti-sludge type polycarboxylate water-reducing agent, from the aspects of changing the molecular structure of the polycarboxylate water-reducing agent, introducing anti-sludge functional groups, and adding sacrificial agents. Suggestions for the future research direction of anti-mud-type polycarboxylic acid water-reducing agent are put forward.

About author:: Wenjuan Zhou,graduated from Beijing University of Technology in materials in 2001, has carried out the research on the recycling technology of construction waste since 2006, taking the recycling treatment of construction waste and the preparation technology of recycled building materials as the main research direction, and based on solving the technical problems in the application of recycled recycled aggregate and recycled micro powder. Presided over or mainly participated in the completion of more than 10 provincial and ministerial projects, including Beijing Science and Technology Plan, such as research on key technologies and applications of construction waste recycling, research on key technologies for further disposal of construction waste, and currently presided over the research and application of key technologies for efficient utilization of the whole industrial chain of construction waste recycling, a major national science and technology project during the 13th five year plan. In the research of construction waste recycling, it has won one second prize of national science and Technology Progress Award and three provincial and ministerial science and technology awards; as the main personnel, it has compiled more than 10 national/industry/group/local standards, such as technical code for construction waste treatment, technical code for fixed construction waste disposal, technical code for classified collection of construction waste, recycled micro powder for concrete and mortar, and published them publicly more than 30 papers. |
