摘要：通过单掺、复掺无机材料和有机材料对再生大骨料进行改性处理，研究了改性再生大骨料混凝土(MAC)与天然骨料混凝土(NAC)、再生骨料混凝土(RAC)的耐久性能差异。结果表明：相同龄期下，NAC的抗渗性能、抗氯离子渗透性能及抗碳化性能均最好，MAC次之，RAC最差；随着龄期的延长，RAC碳化深度的增幅最大，MAC次之，NAC最小。 Abstract: The recycled big aggregate was modified through the single admixture and compound admixture of inorganic materials and organic materials, the difference in durability between modified recycled big aggregate concrete(MAC), natural aggregate concrete(NAC) and recycled aggregate concrete(RAC) was studied. The results show that at the same age, NAC has the best anti-permeability, anti-chloride ion permeability and anti-carbonization properties, followed by MAC, and RAC is the worst. With the extension of age, the increase in RAC carbonization depth is the largest, followed by MAC, and NAC is the smallest.

Abstract: The recycled big aggregate was modified through the single admixture and compound admixture of inorganic materials and organic materials, the difference in durability between modified recycled big aggregate concrete(MAC), natural aggregate concrete(NAC) and recycled aggregate concrete(RAC) was studied. The results show that at the same age, NAC has the best anti-permeability, anti-chloride ion permeability and anti-carbonization properties, followed by MAC, and RAC is the worst. With the extension of age, the increase in RAC carbonization depth is the largest, followed by MAC, and NAC is the smallest.
