我国混凝土外加剂现状及发展趋势

摘要

介绍了我国混凝土外加剂的种类及应用，分析了外加剂研究与实践不匹配，各地混凝土外加剂生产不平衡等阻碍混凝土外加剂发展的问题，指出要加快对新品种减水剂的研究、更新外加剂标准，并促进外加剂的绿色化发展，以保证建筑业的可持续发展。%The paper introduces the types and application of the domestic concrete admixture,points out problems of influencing concrete admix-ture development,such as the mismatch of admixture research and practice and imbalance of concrete admixture production and other problems, and puts forwards some suggestions including speeding up the research of new water reducing admixture,renovating admixture criteria and pro-moting green admixture development,with a view to promote the sustainable development of building industry.
