摘要

摘要：介绍了6种再生骨料的强化方法（聚合物乳液强化法、盐溶液强化法、酸溶液强化法、CO₂碳化强化法、微粉强化法、微生物强化法），分析了各强化方法的作用机理和改善效果，指出了各强化方法的优点与不足，并对未来再生骨料的强化研究进行了展望。

Abstract: Six reinforcement methods of recycled aggregate (polymer lotion reinforcement method, salt solution reinforcement method, acid solution reinforcement method, CO₂ carbonization reinforcement method, micro powder reinforcement method, microbial reinforcement method) are introduced, the mechanism and improvement effect of each reinforcement method are analyzed, the advantages and disadvantages of each reinforcement method are pointed out, and the future research on the reinforcement of recycled aggregate is prospected.

结论

（1）目前再生骨料的强化方法较多，每种方法均存在优势与不足，且再生骨料品质、粒径等也会对不同强化方法的强化效果产生影响。因此，对于不同品质的再生骨料，应根据其特点选择适宜的强化方法，以达到最佳的强化效果。
（2）后续研究中，针对单种强化方法存在的不足之处，可适当选择多种强化方法结合，研究多种强化方法协同作用对再生骨料的强化效果，以提高再生骨料的性能。此外，随着人们对绿色、节能、环保重视程度的增加，CO₂碳化强化法和微生物强化法在未来具有较好的发展前景和工程应用价值，需重点研究，以便尽早实现规模化、工业化应用。
